Can't build - Don't understand error

[Tanje123]

Please provide all mandatory information!
I am trying to build PyMuPDF version 16.10. I installed mupdf however I keep getting the same error. This error doesn't show any information about what is going wrong.

ERROR: Command errored out with exit status 1:

ERROR: Failed building wheel for PyMuPDF

[JorjMcKie]

This error means that pip decided that your configuration does not fit any of the prepared wheels. So it tries to install from sources, which must fails, because you have not installed the base library, MuPDF.
So:
Please provide your system config: OS, version, bitness, Python version, bitness.
Then I am able to track what is going on on your machine.

[JorjMcKie]

I now realized that you did install some MuPDF version.
You are obviously trying to generate PyMuPDF from source intentionally, right?
In that case you need to make sure that PyMuPDF and the installed MuPDF are compatible: same major an minor version, same bitness as your Python installation, correct pointers to MuPDF include and library folders.
Did you follow all instructions for correctly installing MuPDF? Downloaded it from the documented site (not GitHub!), etc.

[JorjMcKie]

Closed for lack of reaction.
