Failed building wheel for manimpango about manimpango HOT 16 CLOSED

I think that AssertionError is not related to this one.

I'm not sure why Cython is not available in the environment pip creates. I think installing it using the classic setup.py install would work for now, follow the steps below:

1. Dowload and extract https://github.com/ManimCommunity/ManimPango/releases/download/v0.4.1/ManimPango-0.4.1.tar.gz to a directory and open a terminal there
2. Make sure setup.py is available in the same directory as the terminal currently is.
3. Install build deps: pip3 install -U setuptools Cython wheel
4. Install: python3 setup.py install

This should install ManimPango and stuff should work, but this isn't really the "correct" way to install but it should work.

I just hit this problem too, again on an M1 Mac with Homebrew python on it. I ran pip3 install git-sim and manimpango is a dependency of that. However I managed to fix the problem by upgrading pip by running the suggested command at the end of the output:

[notice] A new release of pip available: 22.3.1 -> 23.0
[notice] To update, run: python3.10 -m pip install --upgrade pip

Not sure why Cython didn't automatically create manimpango/cmanimpango.c. Maybe Cython isn't installed and something didn't work? From your logs, I see a

Error in sitecustomize; set PYTHONVERBOSE for traceback:
AssertionError:

which is weird. Can you set PYTHONVERBOSE (that's an environment variable) and attach the output (note it'll be really long). Also, how did you install python and what does python --version --version print?

Really sorry, but how do I do that?

I just went to python website (https://www.python.org/downloads/) and installed the latest version.

python --version --version prints zsh: command not found: python while python3 --version --version prints Python 3.10.6 (main, Aug 30 2022, 04:58:14) [Clang 13.1.6 (clang-1316.0.21.2.5)]

You were right, Cython wasn't installed, so I ran brew install Cython but it still didn't solve the problem.

Run export PYTHONVERBOSE=1 first, then run pip and attach its output to a file here.

It should be automatically installed using pip...

from manimpango.

After running export PYTHONVERBOSE=1 and then pip3 install manim I got:
github.pdf

After running export PYTHONVERBOSE=1 and then pip3 I got:
github 2.pdf

Also can you join the discord? Easier to talk and settle things there and then we can come here and update it for future reference and googleability..

It worked, thank you so much!

Great, I'll close this issue then.

I am running into the same problem on my M1 Mac. Tried @markshep's and @naveen521kk's recommendation. No dice. For me, it says that it can't find "cairo.h". Cairo and Py3cairo are both installed. Any thoughts?

from manimpango.

export CPATH=/opt/homebrew/include/
export LIBRARY_PATH=/opt/homebrew/lib/

try installing manim after exporting those env-vars

from manimpango.

The issue with with pkg-config. It was failing and not passing the params accurately. The setup assumes when pkg-config fails that library variables are provided and hence couldn't locate cairo. Relinked pkg-config and installation worked fine. Thanks!

from manimpango.

What do you mean by relinked?

from manimpango.

brew unlink pkg-config && brew link pkg-config

from manimpango.

That operation doesn't do anything meaningful. Did you do that after exporting those environment variables?

from manimpango.

No, I did not export any variables. TBH, I wanted to do that initially, but was unable to figure the right env variables. Linking/ relinking was a hail Mary.
