This comment from @AvacadoCookie should be pinned, IMO.

If anyone is getting errors about Cython or setuptools, and they are using Conda, that comment has the answer.

If anyone is getting errors about Cython or setuptools, and they are using pyenv, there are 2 possible ways to fix it:

1. pyenv local system to set Python back to the system installed Python for this session.
2. pip install Cython setuptools to install the necessary packages to your preferred python installation.

For all users with ModuleNotFoundError: No module named 'Cython' or 'setuptools' reported, please try the following methods to address the problem:

1. Quit conda environment. Now after which python typed in console, the output should be /usr/bin/python.
2. Try again.
3. If the installation still failed, try again after pacman -S cython python-setuptools.

@FalconProgrammer added (next release) thanks!

Could you add the aur package pycharm-community-jre as a conflict? They cannot install side-by-side in the way the packages have been made.

Other aur packages which may conflict:

• pycharm-community-eap
• pycharm-eap

Why does /usr/share/licenses/pycharm-professional/kryo-license.txt have the execute permission unlike other licenses?

@bilthekid

I managed to get it working via

$ yay -S cython $ pip install cython $ yay -S pycharm-professional

In case there are still plans to add aarch64 compatibility here are my changes for aarch64 including jbr. Tested in a VM on Mac M1 with parallels.

My screen doesn't display pycharm correctly. It looks like it's split down the middle with two blank sides. Not sure if anybody else has experienced this but I had the same issue with the community version as well. However in the professional version I was able to activate the trial license.

@bilthekid see https://aur.archlinux.org/packages/pycharm-professional#comment-857099 (EDIT: fixed the link ;) )

I get a ModuleNotFoundError: No module named 'Cython' on building the pycharm. The cython is installed of course. Does anyone has this problem or its just me, and any suggestion how to solve?

@flying-sheep optdepends are optional packages, like a recommendation, but you're right, jupyter-notebook is not the correct package for support Jupyter in Pycharm, fixed.

I’m pretty sure it doesn’t depend on jupyter-notebook (not optionally or otherwise). jupyter-notebook is the legacy frontend. PyCharm probably depends on other things. Their docs say to install the jupyter python metapackage: https://www.jetbrains.com/help/pycharm/jupyter-notebook-support.html#get-started

That metapackage installs the kitchen sink by depending on the python packages jupyer-console, ipykernel, qtconsole, notebook, ipywidgets and nbconvert. I’m sure PyCharm actually only needs ipykernel of those, and probably something like jupyter-server or so.
