I run a Unix server that uses environment modules to handle different software packages. While installing JCVI I have been running into multiple errors. The most recent error I have gotten was this error:

AttributeError: type object 'Callable' has no attribute '_abc_registry'

After doing some googling, I found a solution that told me to uninstall the typing module as there are problems with that module from python 3.7 and above (this server runs 3.8).

I attempted to uninstall this module, but it outputs the exact same error :

AttributeError: type object 'Callable' has no attribute '_abc_registry'

that I had before. I do not know how to go about either removing typing or fixing the error another way.

    Why are you trying to uninstall the typing module? It is built into python and is not meant to be uninstalled. Commented Jun 5, 2021 at 1:46

  • Downgrading packages, especially after the next version comes out, is almost always a wrong and obsolete answer. It may be briefly right until the bugs are fixed. Commented Jun 5, 2021 at 2:40
  • You may be running an old version of pip. Try python -m pip install... or upgrade pip. Commented Jun 5, 2021 at 2:44
