I'm trying to run a web app (built with flask-wtforms and using iGraph) on Pythonanywhere. As igraph isn't part of the already inculded modules, I try and install it using the bash console, as such:
pip install --user python-igraph
How ever, what I get is:
Could not download and compile the C core of igraph.
It usually means (according to other people having the same issue on Stackoverflow) that I need to first install:
sudo apt-get install -y libigraph0-dev
Except, apt-get isn't available on Pythonanywhere, as far as I know.
Is there any workaround to install the iGraph module for Python 2.7 on Pythonanywhere?
python-igraph installed perfectly fine in my account. My guess is that you're facing a different issue to a missing library. Perhaps a network error or something like that.

I want to learn how to code in Pygame (python3.8.5, Ubuntu 20.04). I got pygame installed but it can find the examples. I tried to search for them manually and didn find them either. It seems that the examples were not installed at all.
Here's what I did so far:
The attempt to install pygame with pip failed due to tons of failed dependencies.
python3 -m pip install -U pygame --user
After searching a bit, I found this command, which installed pygame:
sudo apt install python3-pygame
But it fails when I try to run one of the examples:
user:~$ python3 -m pygame.examples.aliens
pygame 1.9.6
Hello from the pygame community. https://www.pygame.org/contribute.html
/usr/bin/python3: Error while finding module specification for 'pygame.examples.aliens' (ModuleNotFoundError: No module named 'pygame.examples')
Any ideas what's wrong?
Thanks!
The Ubuntu Package Maintainers have elected to not include the examples in python3-pygame. Tests and docs are also excluded.
You can access the examples from the pygame github repository.
I have been trying to install Install-Package Google.Apis.Drive.v3 using this source with the difference that I have Ubuntu-18.04 instead of Windows.
I know it may be a simple question but I have been trying research how to do that from this morning. I installed sudo apt install nuget on my machine and have been trying to add packages or as in this case the Google.Apis.Drive.v3 package but no luck.
I went through this source which was useful, but does not carry information I was able to replicate on my Linux machine.
Also this source, this one and this one too. But also this last one is for Windows and was not very useful.
How do I install Google Apis Drive V3 via command line easily as it is documented for windows but on Ubunbtu-18.04?
Thanks for pointing to the right direction for solving this problem.
Solution
The way you install your Drive API's library is depending on the programming language you are aiming to use. These are the following commands to run depending on the different languages to interact with the API (with their respective links to the source of the setup):
Python:
pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib
C#/.NET:
Create a new Visual C# Console Application project in Visual Studio.
Open the NuGet Package Manager Console, select the package source nuget.org, and run the following command:
">Install-Package Google.Apis.Drive.v3
Java:
gradle init --type basic
mkdir -p src/main/java src/main/resources
Node.js:
npm install googleapis#39 --save
For the Browser check out the steps to follow here
I hope this has helped you. Let me know if you need anything else or if you did not understood something.
NOTE: For all Ubuntu-18.04 users that wish to install via command line the correct way is: sudo dotnet add package Google.Apis.Drive.v3
Currently unable to install Pygame via pip:
pip install pygame
Getting this message:
Concerned by it being termed an EOF error, is this an error in the module itself?
There's dev versions available as of now. Get them via
pip install pygame==2.0.0.dev6
Pygame is not compatible with Python 3.8 at the moment. I would recommend you to downgrade back to 3.7 and installing with pip there.
pip is doesn't have pygame up.
But there is a alternative that worked for me. https://www.pygame.org/wiki/CompileWindows
Read and follow the steps correctly and it should install.
you also need to update your code to pygame 2.0.0 code because it's only for 3.8
BTW you have to follow the SDL2 instructions since pygame 2.0.0 uses that.
the above commands worked for me today 3-15-20 with Python-3-8-0 on Linux Mint 19
to get IDLE to recognize pygame.
sudo pip3 install pygame==2.0.0.dev6
I also had to update pip first with
sudo pip3 install --upgrade pip
Pygame requires visual studio C++ build tools to install. Ensure you have these downloaded from here.
Open power shell window and make sure your internet is on
Then type the following command
pip install pygame
It will automatically download it for you and also install it
Again make sure your internet is on
I have python 3.8.2 and it worked on my pc
I use fedora 20, Python 2.7 and virtualenv 1.10.1. I want to install pygame in virtualenv and I get
You are installing a potentially insecure and unverifiable file. Future versions of pip will default to disallowing insecure files.
HTTP error 400 while getting http://www.pygame.org/../../ftp/pygame-1.6.2.tar.bz2 (from http://www.pygame.org/download.shtml)
Could not install requirement pygame because of error HTTP Error 400: Bad Request
I found this in GitHub, so I tried without success
pip install git+http://github.com/xamox/pygame
Asking for missing dependencies. I know that I have to install sdl*. Can I do it in virtualenv or do I have to do it on the system? Any recommendation?
I installed PySDL but still nothing
Finally what I did to install pygame on virtualenv is:
su -c "yum-builddep pygame"
due to pygame installer is waiting for user confirmation about missing dependencies I need to pipe a "yes". So
yes y | pip install hg+http://bitbucket.org/pygame/pygame
or
yes y |pip install git+http://github.com/xamox/pygame
The smpeg-config dependency is only available on fedora16 so I ignored and that's worked.
I had the same issue in Ubuntu, and fixed it with:
sudo apt-get build-dep python-pygame
Interesting, I've seen this solution in some resources, but it didn't work for me, because build-dep looked not like an option, but like some package to install, so I tried to run apt-get install build-dep. Of course, with no success. #b10n1k 's answer helped me to figure out my mistake. :)
I am currently using the Macbook pro with OS 10.9.
And I was trying to install octave to my mac when I found that I have to install gnuplot before I could use the plot in the octave. So I try to install gnuplot using the homebrew. However,the brew got stuck when trying to install the gd, because China's network fails to link to the site https://bitbucket.org/libgd/gd-libgd/downloads/libgd-2.1.0.tar.gz
So I use goagent to download the package via chrome and try to manually install the package and try to link it using brew by the instruction from https://github.com/mxcl/homebrew/wiki/FAQ
And after make install, when I try to use:
brew link libgd
the brew prompt error message:
Error: No such keg: /usr/local/Cellar/libgd
And I followed exactly the process in the FAQ diy.
$ tar -xvf l-ibgd-2.1.0.tar.gz
[snip]
$ cd libgd-2.1.0
$ brew diy
-DCMAKE_INSTALL_PREFIX=/usr/local/Cellar/libgd/2.1.0
$ ./configure --prefix=/usr/local/Cellar/libgd/2.1.0
[snip]
$ make && make install
[snip]
$ brew link libgd
Error: No such keg: /usr/local/Cellar/libgd
The configuration and installation are without any error. Any suggestions? Thx a lot!
There are several things wrong here, and I'm not sure whether they are Homebrew bugs or incomplete transcription on your part.
First, the package is called gd, not libgd, so there would be /usr/local/Cellar/gd, not /usr/local/Cellar/libgd.
Second, brew diy appears to suggest a cmake invocation, but gd uses autotools, so that is wrong.
Ultimately, this should work if you string it all together correctly, but actually, if you have problems with reaching a mirror over http, I would just put the tarball somewhere else and edit the formula file (brew edit gd) to point to that new location. Much easier, and you can even save your modification in a local Git branch.
