Error when installing ManimPango via pip on windows about manimpango HOT 13 CLOSED

Many thanks for your patience!! It's finally installed successfully.

from manimpango.

Hey @YishiMichael! More of a general comment than a concrete solution for your issue here:

@naveen521kk also has put some thought into refactoring Text, not sure what the current status is but you can find a sketch of the plans at ManimCommunity/manim#2355. To avoid further fragmentation between Grant's personal version of Manim and the community version, we should try to stick to the same version of ManimPango, meaning that all changes to the interface should also be ported to ManimCommunity/manim. We'd certainly love to have you as a contributor! :-) (And even if you prefer to stick to 3b1b/manim, I'm sure we will find a suitable way for collaborating.)

from manimpango.

@behackl Yeah I'd like to contribute to ManimCE as well!
I've read #2355 and was pleased to see the new implementation design. I'm looking forward to collaborating with manim community, started with Text class.

from manimpango.

Thanks for the contribution. As @behackl mentioned it would be great if the changes you do on Grant's version related to ManimPango/Text API be ported to ManimCommunity/manim.

Also, I have been planning to refactor the Text API ManimCommunity/manim#2355 and also have thoughts to provide a stable API here #28; suggestions about them welcome. I have been waiting for the refactor period (which we announced a while ago) to be done, but it seems like we won't have anything like it anytime soon; which means I would start working on it anytime soon (probably after the exams which will end by march).

Failed to open 'D:/msys64/mingw64/lib/pkgconfig\freetype2.pc': Too many open files
Package 'freetype2', required by 'harfbuzz', not found

This is the error from pkg-config, which seems like just restarting your computer and re-running the install should fix it.

from manimpango.

It doesn't work... But thanks for replying. I may try other means.

Maybe try running pacman -Qkq in that shell to check whether all the files are installed correctly? Also, try running pkg-config --libs --cflags pangocairo manually on that shell to see if it errors out in that case?

from manimpango.

It goes into error when I run pkg-config --libs --cflags pangocairo. The message is

$ pkg-config --libs --cflags pangocairo
Failed to open 'D:/msys64/mingw64/lib/pkgconfig\freetype2.pc': Too many open files

from manimpango.

Does the pacman command suceed? Also, does a file called D:/msys64/mingw64/lib/pkgconfig\freetype2.pc exists?

from manimpango.

Also, what does pkg-config --version and which pkg-config commands print?

from manimpango.

The file D:/msys64/mingw64/lib/pkgconfig/freetype2.pc exists. And here's the output:

$ pacman -Qkq
mingw-w64-x86_64-make /mingw64/bin/mingw32-make.exe

$ pkg-config --version
0.23

$ which pkg-config
/mingw64/bin/pkg-config

from manimpango.

Hmm, I'm wondering why pkg-config is used instead of pkgconf, I remember they replaced pkgconf by default. Did you ever update the packages there ie run (pacman -Syu)? If yes, can you run pacman -S mingw-w64-x86_64-pkgconf and then press yes for all questions asked from Pacman. If not, please update first using pacman -Syu, it should ask about replacement and just input yes there.

Doing so should fix the issue I think.

from manimpango.

I've run the commands provided, i.e.

$ pacman -Syu
$ pacman -S mingw-w64-x86_64-pkgconf

I've also restarted my computer.
They worked --- the error changed :(

Now the problem is https://www.msys2.org/news/#2021-12-21-potential-incompatibilities-with-newer-python-setuptools I should've updated the README file about it. Simply, running export SETUPTOOLS_USE_DISTUTILS=stdlib before the pip command should work.
