Building wheel for pyscard (setup.py): finished with status 'error'

I have pyscard within requirements.txt. Therefore the build on readthedocs is failing:

Running setup.py install for pyscard: finished with status 'error'
  error: subprocess-exited-with-error
  
  × Running setup.py install for pyscard did not run successfully.

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

× Encountered error while trying to install package.
╰─> pyscard

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

I have tried to skip pyscard in docs/conf.py:

autodoc_mock_imports = ['pyscard']

and in setup.py:

if os.getenv('READTHEDOCS'):
        requirements = [x for x in requirements if "pyscard" not in x]

but I still get the same error. Have you encountered something similar? If so, how have you solved the problem?

This header file is provided by pcsc-lite. Install libpcsclite-dev (or similar) package.

I added into .readthedocs.yml:

build:
  apt_packages:
    - swig
    - pcscd
    - libpcsclite-dev

If pyscard is not required to build your documentation, you should remove it from your documentation requirements.txt. This is the most common case.

You may need to split your current requirements.txt:

  • requirements.txt with all the dependencies
  • docs/requirements.txt with only the dependencies to build the documentation (without pyscard)

Then, in your readthedocs.yaml file (see https://docs.readthedocs.io/en/stable/config-file/v2.html), you can use:

python:
  install:
    - requirements: docs/requirements.txt

On the other hand, if pyscard is required to build your documentation, you can take a look at the FAQ from the documentation https://docs.readthedocs.io/en/stable/faq.html#i-get-import-errors-on-libraries-that-depend-on-c-modules
