Installing Polymer for the first time - polymer

I Right-click or CTRL+click on the icon-toggle/demo folder and choose Run according to these instructions and I get:
Unable to deploy the current selection; please select an application to deploy.

I ran in to the same issue. All i t took to fix it was restarting the Chrome Dev Editor.

Chrome debugger in Visual Studio Code gets stuck

If I try to start debugging in Visual Studio Code, I get the following error:
No matter what launch.json I use I always get this error. Tried a lot of launch.json configuration. Don't know why it tries to load localhost:9876/debug.html when I set the url to localhost:8100.
My app is running on 8100 port. Debugger for Chrome is plugin is installed. How could I get rid of this error?
The fix was quite easy. For a long time I did not make a restart to my computer. After a computer restart the debug is working now.

Unable to install MySQL on Windows 10 - Installer hangs indefinitely

I am trying to install MySQL on a Windows 10 PC. I downloaded the installer package and followed those steps
Went to https://dev.mysql.com/downloads/windows/
clicked on "MySQL Installer"
Scrolled to Generally Available(GA) Releases section
Clicked on "Windows (x86, 32-bit), MSI Installer" (mysql-installer-community-5.7.21.0.msi) and it started the download.
Once the download was complete, I double clicked on the installer and it gave a usual pop-up for any installation like,"Do you want this app to make changes to your device?" after clicking on "yes" for the answer to this question, it shows "Please wait while Windows configures MySQL-Installer-community" like below screenshot.
And then it keeps showing this installation progress bar for a very long time. Like more than 7-8 hours and the installation never completes
So it seems something is wrong as I don't think MySQL installation needs this long time. I tried to restart my computer and then delete any files related to MySQL from my computer and then started the whole process of installation again. But no luck yet
Anyone has any suggestion on this or did anyone face this kind of issue before? If so, is there a fix or a work around for this?
ok. So finally this is how I resolved my issue. And I found the solution at https://bugs.mysql.com/bug.php?id=82004 . The solution to this problem is to close an open "Windows installer" (the one using 0 memory and CPU) via task manager and the installation should begin running as expected.
Alternative solution: Use an administrator command prompt to run the MySQL installer on Windows 10. Details:
(Note: if you have any problems in the following steps, you can try to restart your computer. Then restart the steps.)
Right-click the Start/Windows icon in the bottom-left corner of Windows.
Click: Windows PowerShell (Admin).
A window asks: Do you want to allow this app to make changes to your device? Click: Yes.
Change to the directory with the MySQL installer. For example, if you downloaded the MySQL installer, type something like:
cd C:\Users\my_username\Downloads\
(Note: To save some typing, you can type a few characters, and then press the tab key, to make Windows show you various auto-completion options.)
Run the MySQL installer. Type something like the following command---make sure to include the period and backslash at the beginning---and press Enter.
.\mysql-installer-community-8.0.11.0.msi
Note: The idea of using an administrator command prompt came from John Geffe, in the link below, which was cited in the answer written by the original poster (user8425592):

Bug #82004 MySQL Installer freezes during "Please wait while Windows configures..." phase

To get past this problem I had to run the .msi installer from an the
Administrator command prompt. Hopefully this helps someone in the
future.

John Geffe: Thanks! Your note on installing as an administrator seems
to have taken care of the problem.
this did the trick for me: https://ao.ms/mysql-community-server-msi-installer-hangs-on-windows-10/
run cmd (commandline) as Administrator
cd to your location that you downloaded the .MSI to
run the “msiexec” commandline tool with option “/i” as follows:
msiexec /i [replace with file name]
example: msiexec /i mysql-installer-community-5.7.20.0.msi
Another thing that worked for me was running the installer in compatibility mode for previous version of Windows. You can try that as well.
Go to the link you provided (the first one) and try installing MySql Workbench. That is the version that is commonly used, and one that I verified works in Windows 10. Here is the link: https://dev.mysql.com/downloads/workbench/
Obviously, make sure you choose the right architecture, have the correct permissions to install software, and have enough space on your hard drive, or on the machine you are installing to.
Please install "Update for Visual C++ 2013 and Visual C++ Redistributable Package" from Microsoft Site "http://download.microsoft.com/download/0/5/6/056DCDA9-D667-4E27-8001-8A0C6971D6B1/vcredist_x64.exe"
Please look here at https://support.microsoft.com/en-in/help/3179560/update-for-visual-c-2013-and-visual-c-redistributable-package
Yes, I also got the same problem on my Windows 10.
Followed the Powershell solution and it worked.
Just repeat the above:
Click Start on bottom left corner
Scroll down the application list until Windows Powershell
Select Windows Powershell again on sub-menu
Type in cd (to change to your .msi folder)
Type .\xxxxx.msi (this is the installer file name)
All good.
Once you install the above package run the installer again and do the steps. You will be able to install the mysql-installer-community-5.7.21.0 for 64 bit windows 10
closing Windows Installer instances using 0 memory and CPU helps me to get past this problem.
For me on Window-10 machine, there was a problem with the "mysql-connector-net-8.0.11.msi". I was not able to uninstall this and hence all my subsequent efforts to install MySQL were failing. I did the following to overcome this issue.
Re-installed "mysql-connector-net-8.0.11.msi" Get it here and used the 'Repair' option
Installed the "mysql-installer-web-community-8.0.11.0.msi"
These two things solved my problem. Hope this helps.
The reson is your antivirus didn't allow the mysql, so Disable protection(until restart),( in your task bar right side click the arrow and right click to antivirus,to select (Disable protection(until restart)).then restart your computer again install mysql installer it will work.
For this issue just run .msi file in command administration like
E:\mysql-installer-community-8.0.20.0.msi\
follow this link:
https://kb.foxitsoftware.com/hc/en-us/articles/360040660611-How-to-install-MSI-from-command-line-with-administrator
In my case, an upgrade to 5.7.29 on Windows 10 via mysql-installer-web-community-8.0.20.0.msi, the install froze "backing up the database". The log tab showed no activity for 8 minutes. I clicked on cancel, then at the "are you sure" prompt I declined to cancel, and all of a sudden the install was working again. Very strange...
I encountered the same problem, preparing but can never get started. Tried to close other installation programs with no use, but I took the inspiration and proceeded with restart the computer and it worked nicely. So, I think the issue is to get rid of everything that could be in the background running that somehow interferes the installation.
You should run the installer as an administrator but this specific installation may not provide an option for this. Some might have it but it's most likely that it's unavailable for many users. So you should run it in cmd or powershell. And don't forget to run these shells as an administrator coz that's the whole point here. Once there, navigate to the installer's location which usually is in the downloads directory and run it using this command ./name.msi
Make sure no other ongoing installation of this instance. Close it if there exists one and undo the changes made by uninstalling it from the panel. If still facing difficulties, try restarting your machine and repeat this procedure...
Have fun
I had the same Problem, A simple solution is to give access the "SYSTEM" to the msiserver...I know, this is hard to understand what I am saying....You can Simply see this Video and you will definitely find the answer https://www.youtube.com/watch?v=6SdXMjXmnUk, It is a matter of just 3 minutes...
I encountered the same issue of taking too much time to install mysql community installer.I tried 3 times by cancelling the installation and restarting to perform a new installation.But had same issue. I tried 2 things
First to end all tasks associated with installation which I performed for installing mysql using Task Manager
Reinitiated the installation but didn't solved my issue.
Secondly tried to install through Windows Powershell as admin, which solved the problem.
Click on the Windows icon/start on the bottom left corner.
Right click and select the option Windows Powershell (Admin).
A pop up window will ask Do you want to allow this app to make changes to your device?....Click Yes.
Now cd to your downloads folder/wherever you downloaded the .msi file (For example cd C:\Users\MYPC\Downloads).
Once you reach to the folder where the .msi file is kept, run the following command.
.\mysql-installer-web-community-8.0.23.0.msi (Note: this is the version which I have downloaded, modify as your version).

Browser-sync not refreshing when I save (Chrome and sublime text 2)

When I save changes to my css code, Browser-sync doesn't refresh the browser automatically. I still have to click on my browser window and hit F5 to see the changes I have made. I installed npm and browser-sync and it shows I am connected to browser-sync. I am using Sublime Text 2 and Chrome (Dev 56.0.2924.87) on a windows 7 operating system.
Any ideas on how to fix this? Thank you!
I found a solution. I had to fix or update deprecated npm packages. How to determine path to deep outdated/deprecated packages (NPM)?
What also helped - Gulp. I used Gulp in combination with browser sync and now my browser automatically refreshes when I save changes.
I used the following link to guide me through using Gulp for the first time: https://css-tricks.com/gulp-for-beginners/

Magento connect stucks at Checking dependencies of packages

when ever I try to install some extension magento connect stuck at:
Checking dependencies of packages
and nothing else is shown after even waiting for hours. Any suggestion please.!
When you install extension in magento is very important that you follow two simple steps
First Step: Disable the cache;
Second step: Go in system-> tool -> compilation and disable the compilation
Then install your extension and if anything is ok, go in admin panel, logout and login then, enable cache and compilation again.
If you have other error maybe your extension not is compatible with your magento version or there is some error in this extesion... Anyway try this suggestion because it works. If my helped works for you please left a flag in this answer. response.

PhpStorm is not starting up

I just downloaded PhpStorm 5 on my quite fresh ubuntu.
During the first start I installed a couple of plug-ins.
Now - after the installation of those plug-ins - PhpStorm is not starting up anymore.
No splash screen is showing up. No error gets written on the terminal:
gue#ubuntu:~$ phpstorm
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)
gue#ubuntu:~$
What shall I do with that drunken sailor?
I can't find any logfiles, no configuration file/directory in my home directory.
Since I'm used to Eclipse I've no clue where to look for a trace in this IntelliJ derivate...
If you're on Windows deleting the following directory helped me:
C:\Users\<user>\AppData\Roaming\JetBrains\
Some plug-ins can cause problems and prevent IDE from starting, if it happens, you should delete the directory containing plug-in manually. Location of this directory depends on the system and product, details are available in the FAQ.
For PhpStorm on Linux it would be ~/.WebIde50/config/plugins.
This happend to me too, I had created a custom vmoptions file, and entered incorrect values. I fixed it by deleting it in ~/.WebIde50/phpstorm.vmoptions
i had the same problem , i fixed it just with removing the file C:\Users\.PhpStorm2016.2
In linux, I fixed it by deleting vmoptions file of PhpStorm and then launching it again:
mv ~/.config/JetBrains/PhpStorm*/phpstorm64.vmoptions ~/.config/JetBrains/PhpStorm*/__phpstorm64.vmoptions
It might be possible if openjdk is installed then phpstorm not opened.
So remove first then follow steps that given in below link.
I solve the problem same way.
wiki.jetbrains.net/intellij/Installing_and_running_PHPStorm_on_Ubuntu
Here is how you fix this: Rename C:\Users\USERNAME.PhpStorm2016.3 to something else (anything, like PhpStorm2016.whatever) , it will start the program if you click on the phpStorm icon, then choose to import settings, and you're good to go ;)
I am using PhpStorm2020.2.1. I referred to Configuration directory. I accessed the folder %AppData%\JetBrains\PhpStorm2020.2, renamed it just in case I may need some files in future.
Voila! I can start my PhpStorm2020.2.1 again!
I had this problem yesterday and my OS is windows 10. phpStorm suddenly did not work and when I click on it nothing happened. I just downloaded JDK from this link (https://www.oracle.com/java/technologies/javase-downloads.html) and after installation, I set the environment value in the system setting for my java directory. You can use this link to set the environment (https://javatutorial.net/set-java-home-windows-10)
For me I had to remove all cache for the IDE located in:
~/.cache/JetBrains/
I have changed the VMOptions under the Help menu on MacOS and it just would not start up again. It just silently failed every time. I found the file at /Applications/PhpStorm.app/Contents/MacOS/phpstorm and ran it in the terminal, which gave me an output with the following error:
Invalid ReservedCodeCacheSize=3072M. Must be at most 2048M.
Luckily, it also gave me the path to the VMOptions file in one of the rows of the output, parseVMOptions: /Users/barnabas/Library/Application Support/JetBrains/PhpStorm2022.3/phpstorm.vmoptions in my case, so I could change it back to a valid configuration. Crisis averted.
Simple
Go to your task manager
end any task on php-storm
and restart the ide again
it will work
Open Terminal Linux Ubuntu 20.10
YOU#USER:~$ cd ~/.config
YOU#USER:~/.config$ ls
Obs: Locate the >>> JetBrains <<< folder, after that delete it your default app settings will disappear more it will open again
YOU#USER:~/.config$ sudo rm -rf JetBrains/
Open PHPSTORM
