How do you run pip to get to this error?

[project2501a]

on Python 3.8.5 and same on Python 3.9.0 pip install pycairo

same result for PyGObject pip install PyGObject

same final error

ERROR: Could not build wheels for ...... which use PEP 517 and cannot be installed dire..............

[naveen521kk]

I remember we created wheels for windows?

[lazka]

yes, I don't know why they aren't used here.. they get used on my machine.

[naveen521kk]

for me also. also on many other systems which uses manim.

[naveen521kk]

@project2501a Can you try the below command?

pip3.8 install https://files.pythonhosted.org/packages/01/94/b16f92f4aac89739cb31243bcf4346d2c5ef468db982804ff378e9712589/pycairo-1.20.0-cp38-cp38-win_amd64.whl

I really don't know why your computer's pip uses wheels maybe it's configured to not use wheel? What this does it pulls wheel from PyPi and install(the way it should do usually).

@naveen521kk hello , returns already installed, i uninstalled it and used your command, it went fine, weird

python has just been installed, from the installer

Hi, @naveen521kk ,

I got the similar error in my Ubuntu 16.04 system

Pip subprocess error:

Any hints to solve it? (like the link you provided? )

Hi @amiltonwong There are no wheels for pycairo outside of windows sadly. So you would have to compile from source, the above error message says it couldn't find cairo, which can be installed from your package manager. See documentation for more information.

Yes, I think @naveen521kk is right. I had a similar pep517 error message using pip. After I installed cairo ( https://pycairo.readthedocs.io/en/latest/getting_started.html ) pip installed pycairo succesfuly.
