Getting "error while generating package metadata" when installing TkFontAwesome

Question

I'm trying to install TkFontAwesome using python -m pip install tkfontawesome, but always get the following error:

Collecting tkfontawesome
  Using cached tkfontawesome-0.2.0-py3-none-any.whl (405 kB)
Collecting tksvg==0.7.4
  Using cached tksvg-0.7.4.tar.gz (50 kB)
  Preparing metadata (setup.py) ... error

  × python setup.py egg_info did not run successfully.

  note: This error originates from a subprocess, and is likely not a problem with pip.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

Never had any problems installing packages using pip before. The file subprocess.py IS in \Thonny\lib\ if this WinError 2 means that.

I'm using:

• Python 3.7.7
• pip 22.0.3
• Tk 8.6.9
• Thonny 3.2.7
• Windows 10

So far i've tried:

• to update my pip and setuptools (they're already up-to-date)
• to install TkFontAwesome using ez_setup
• to install TkFontAwesome using --use-deprecated=backtrack-on-build-failures

No use. Anyone have any ideas what to do next? Thanks in advance.

Answer 1

Try add this after your pip3 install package:

    --use-deprecated=backtrack-on-build-failures

eg, if you want:

    pip3 install imageAI

then:

    pip3 install imageAI --use-deprecated=backtrack-on-build-failures

copy from there.
