Connector installation error (MySQL installer) - mysql

I'm installing MySQL 5.6 Community Edition using MySQL installer and everything was installed properly except for "Connector/Python 2.7 1.1.6".
Upon mousing over, I get the error message "The product requires Python 2.7 but it was not detected on this machine. Python 2.7 requires manual installation and must be installed prior to installing this product"
The problem is, I have Python 2.7 installed in C: already and I can't seem to direct this detection towards where I have Python 2.7.
(I am using Windows 8)

Check if there is any install path dependencies on your installer to figure out if your python is in the right place.
But I recommend that you install the connector you want manually.
P.S. Are you sure you need the connector? Or you just saw the error and assumed you need it?

Mysql Connector 8.0 and Python 3.8

I am using Windows 10. I have python 3.8.2 32 bit installed. I am trying to use mysql-installer-web-community-8.0.20.0.msi the connector for Python. The connectors are grayed out and not available. The error message says Python 32-bit not installed. I see old threads claiming you need Python 3.4. The documentation here: https://dev.mysql.com/doc/connector-python/en/connector-python-versions.html claims this will work with Python 3.8.2. Do I need a different MySql installer? If not, what am I doing wrong?
Thanks,
Scott
I am not sure why I was using the MySQL installer to install libraries for Python. In hind-sight, that doesn't make sense. Use pip to install the drivers like
$ pip install mysql-connector-python
# or
$ python pip install mysql-connector
# or for >= Python 3.9
$ pip install mysqlclient
It is not entirely clear what the difference is, but, the first of the three solved the problem.
I faced similar issue while working with MySQL 8.0.18 with Python 3.8 on Windows 10 64 Bit Machine.
And I used the following workaround -
Ensured that all the installers used were 64-Bits installers for My SQL and Python since my machine is Windows 10 64-bit machine.
Ensured that Python Connector for MySQL supported the corresponding python version from https://insidemysql.com/category/mysql-development/connectors/python/ Incase of issues or lack of information downgraded MySql by minor version.
Downloaded independent MSI for Connector from - dev.mysql.com/downloads
Manually installed the downloaded Connector MSI.
Hopefully this information will help you troubleshoot your issue as well by using corresponding 32-bit versions.
If your CPU architecture is 64 bit then be sure that you download MySQL Connector 64 bit version. 32 bit installers would also work but sometimes occurs minor errors. Also MySQL Connector Python requires Python to be in the system’s PATH. Installation fails if python cannot be located. Add python.exe path to System PATH varible. So that MySQL connector can find the execution file.
It is sadly known that MYSQL has low compatibility with python.
For example, I have stepped into this issue while trying to install mysql-python (a terrible one!) and this other issue while using mysqlclient.
There are a lot of python connectors for mysql, you can try some and see one by one if they work. I would recommend pymysql.
However, I would recommend you to use a Postgresql db with python, it really works like charm, and if you want to have a local DBMS/GUI/workbench to work on it, you can use PgAdmin.

Installing MySQL 5.7 on Windows

I am struggling to install MySQL 5.7 on Windows 10 after a clean removal of MySQL 8.0. The installer defaults to the version 8.0.12, with no way for me to change it.
When I run the installer (which has the version number 5.7.23.0), I am prompted to the following screen:
... despite the fact that this installer is (supposedly) for specifically the version 5.7.
I am unfamiliar with the manual installation process, so I was wondering if someone could help me install MySQL 5.7 on my PC (preferably all the other MySQL products such as the Connector and the Workbench as well). I've been trying to follow the instructions on the official documentation, but I stopped because I had no idea what I was doing.
I removed my MySQL 8.0.11 installation
Then I removed all the MySQL folders in the program and data folders
I disabled the gateway
Then started the installer for version 5.7.24 and that was oke.
First download all requirements and install them first
Then the installation was done. At the Installation screen, the status was ready to download, but I ignored it first and then I enabled the gateway again and the installation was fine.
At the installation screen it was clearly that version 5.7 would be installed. It only installed some 8.0 products (like the Shell, Router, connectors etc).
After checking, i've got Workbench 8 but MySQL 5.7.24

Postfix install fails. MySQL conflict

I'm using CentOS 6, and trying to create a virtual mirror on a new server of an old one (which someone else setup). As much as possible, I want keep everything with the same version, but I've started from scratch and am documenting everything. By default, yum would install MySQL 5.1.73. I downloaded MySQL community v5.1.69 and installed it manually. This required installing a "shared compatibility" package of MySQL v5.1.69 first, and removing mysql-libs.x86_64. With that in place, I successfully mirrored MySQL.
Now, I'm trying to install Postfix. Yum wants to pull version 2.6.6-6. This fails because it requires a dependency that it attempts to install as well: mysql-libs.x86_64 v.5.1.73-5. It splits out a pile of errors messages which are all similar to this:
Transaction Check Error:
file /usr/share/mysql/charsets/Index.xml from install of mysql-libs-5.1.73-5.el6_6.x86_64 conflicts with file from package MySQL-server-community-5.1.69-1.rhel5.x86_64
My old server is using postfix v2.6.6-2, which is apparently compatible with MySQL v5.1.69. I found the rpm for that version of postfix. It doesn't install, because it requires mysql-libs. I can't install mysql-libs v.5.1.69, because it conflicts with the MySQL community edition (also 5.1.69) that I installed. I tried to install the MySQL 5.1.73 "shared compatibility" package, but that conflicts with MySQL community too.
I'm going in circles. Is the only way to break this chain to uninstall MySQL community? Must I just use the v5.1.73 default, and the Postfix 2.6.6-6? I don't expect any real problems, but I'm going to end up with slightly different versions of MySQL and Postfix then I am trying hard to mirror.
I gave up, uninstalled all the MySQL community packages, and just installed the out of the box yum MySQL and Postfix. That works, but I now have different versions of this software on these two servers as a result.

mysql installer fails to recognize python 3.4

I'm trying to istall mysql server on a windows 7 machine - that has python 3.4.3 installed. However, when trying to install the python connectors for 3.4, the installer fails to recognize the python installation, saying python 3.4 is not installed.
Has anyone solved this issue before? I'ts driving me nuts...
Just to add to the murkiness, I had the same error with current version of MySql install when attempting with python 3.5 installed (which is the latest python download). Long story short, I uninstalled python 3.5, installed python 3.4.4 (which interestingly didn't update PATH so I updated it manually) and reran installer and it found the python installation.
So my conclusion is the MySql installer is tied to certain versions of the add-on products which in this case meant specifically python 3.4
just in case anyone else has this issue in future. Look at what bit version you have for Python 3.4. When I installed 64 bit version of Python 3.4, this issue went away.
I ran into a similar issue with Python 3.7.2.
In my case, the problem was that I tried to install the 64 bit MySQL connector, but had the 32 bit version of Python installed on my machine.
I got a similar error message:
Python v3.7 not found. We only support Python installed using the Microsoft Windows Installer (MSI) [...]
The problem just went away by installing the 32 bit MySQL connector instead.
From my experience if you have both Py2.7 and Py3.4 installed when installing the mysql connector for py3.4 you will run into this issue. Not sure of the WHY but for some reason if you have py2.7 installed, the py3.4 mysql connector recognizes that version first and just assumes that you have py2.7 installed and does not recognize that py3.4 is installed.
The only way I have found around this is to uninstall py2.7 and then install the py3.4 mysql connector. You can always install py2.7 again after the fact.
I had 3.6.X version and it could not see it; I uninstalled it and installed 3.4.0 version and it passed the requirement.
https://www.python.org/downloads/release/python-340/
Had the same problem and have fixed it. Using a Windows 7 PC and I already had multiple versions of Python installed.
Uninstalled all versions of Python from my PC
Uninstalled the failed MySQL install
Restarted PC
Re-installed Python 3.7 64-bit (the currently required version for MySQL)
Installed the Python 3.7 MySQL Connector separately through the link below
https://dev.mysql.com/downloads/connector/python/
Once that was installed, restarted the MySQL install
The MySQL Installer window will open and already show the Python 3.7 MySQL Connector in the list of products
Click "Add" at the top-right and select all of the products you want and then install them
You should then be able to complete the MySQL setup
I was looking for an similar answer. The correct answer is that there is a bug in the mysqlconnector MSI. When python installs, it creates a registry entry under HKLM Software\Python\PythonCore\3.6-32\InstallPath however, the MSI for mysqlconnector is looking for installation path in the registry Software\Python\PythonCore\3.6\InstallPath as part of the RegLocator/registrypath variable.
Use ORCA to edit the MSI, change the RegLocator so that -32 is in the path. It will install now without error or changes to the system.
I had same problem with python 3.4, all I did was installed python 3.4 version for all users. and added system variable as per this page. it worked for me!
Hope that helps.
Make sure you have the 64bit version of whichever version of Python you are running. It can be downloaded from here:
https://www.python.org/downloads/windows/
Just had the same problem and this solved it for me. I also uninstalled all previous versions of Python before running the mysql setup
I had this problem until I discovered I had installed python based in another architecture (32b). MySQL required 64 bit.
Had the same problem with Python 3.7 when trying to install MySQL in Windows 10. It was fixed by installing the 64-bits version of Python, not selected by default when going to https://www.python.org/downloads/.
I found it in https://www.python.org/ftp/python/3.7.3/python-3.7.3-amd64.exe
Here is a much simpler work around:
pip install mysql-connector-python
Is the same package that MySQL is having trouble installing. Just use pip to install it.
Next, go back to the installation style and select "Manual" instead of "Developer". They are identical, but "Manual" allows you to remove packages. Just remove the "Connector/Python" package from the list to be installed.
Carry on with the install, you're done.

MySQL driver for Rails in Windows 7 x64

I've got problem with connecting to MySQL database on my freshly installed Windows 7 machine.
I'm getting this error when I try to migrate my database.
!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install
the mysql gem and try again: gem install mysql.
rake aborted!
193: %1 is not valid Win32 application - C:/Ruby/lib/ruby/gems/1.8/gems/mysql-2.8.1-x86-mswin32/lib/1.8/mysql_api.so
I currently have installed
ruby 1.8.6 (2008-08-11 patchlevel 287) [i386-mswin32]

My colleague had a similar problem while running rails on Windows 7.
He had to replace the libmySQL.dll (in the PATH) with the one from InstantRails.
I spent hours trying to get MySQL and Rails to play nicely on Windows (albeit XP, both 32 and 64-bit versions). I finally gave up since my production box was running Linux (on which Rails and MySQL play very nicely) and just used SQLite 3 for development. No headaches to get it working and it runs fast enough for development purposes.
However, I did hear of some people that had luck replacing one of the DLLs provided by the gem with one provided by the official MySQL distribution. Also, some people simply didn't have this DLL at all which was causing problems. In the end, it didn't work for me, but hopefully you will have more luck.
For Rails or DataMapper or whatever to talk to MySQL you need a 32-bit driver in Rails\bin. The driver is called libmysql.dll. Even if you have a 64-bit server you need a 32-bit driver.
64-bit driver will fail will ruby/gems/1.8/gems/do_mysql-0.10.2-x86-mingw32/lib/do_mysql/1.8/do_mysql.so: 193: %1 is not a valid Win32 application.
A wrong 32-bit version will crash with memory allocation error or something weird like that (suggested solution to take libmysql.dll from another project may not work with newer versions of MySQL).
I am new to this rails. I just have passed the same issue in vista. after downloading libmySQL.dll (in the PATH) with the one from InstantRails it starts working.

The solution to this problem is to simply install the 32-bit version of mysql.
Fast forward to March 2012. I solved this problem on windows 7 x64) by renaming my Ruby\b\bin\libmysql.dll and then copying libmysql.dll from C:\Program Files (x86)\MySQL\MySQL Connector C 6.0.2\lib\opt to Ruby\bin
There was a newer version of libmysql.dll at C:\Program Files (x86)\MySQL\MySQL Workbench CE 5.2.37 but the gem didn't like the non 6.x version.
Could this be related to Ruby on Rails Win7 x64? ? If so, what was the fix again (couldn't figure it out from the first answer) ?
Another option which has worked for me is to download the 32bit version of mysql for windows and just keep the libmysql.dll and add the location of this DLL to the windows PATH.
Adding the libmySQL.dll from InstantRails to a dir in my path worked for me too. It's really sad that we have to do this sort of thing though. I'd like to see the gem, or MySql itself, install this DLL properly.
I'm running the current versions of everything on WinXP SP3: Ruby 1.9.2p0, MySQL 5.5, mysql 2.8.1. This issue is still present and to fix it I had to copy the Instant Rails libmysql.dll into my C:\Ruby192\bin directory. I initially copied the libmysql.dll file that came with MySQL 5.5 but that caused a seq fault!
