ERROR: Failed building wheel for twisted-iocpsupport – Docker

error image

I was trying to install daphne===4.0.0 but I keep getting this error,

ERROR: Failed building wheel for twisted-iocpsupport

    Building wheels for collected packages: twisted-iocpsupport
  Building wheel for twisted-iocpsupport (pyproject.toml) ... error

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

    This error occurs because twisted-iocpsupport is not supported by python 3.11
    Consider going back to any versions between 3.6 and 3.10
    that fixed the problem for me.
    Go to twisted-iocpsupport documentation and see the versions of python it supports

    According to the docs,

    Applications must not import names from the twisted_iocpsupport package directly.

    So, if you’re using any file with package versioning (requirements.txt, project.toml, etc.), you should remove-it manually.
