Root Cause

The specified extra (e.g., [extra]) does not exist for the package on PyPI.

generic

中文

指定的额外选项（例如 [extra]）在 PyPI 上的包中不存在。

Workarounds

  1. 95% success Check the package's available extras on PyPI 
    Visit https://pypi.org/project/mypackage/ or run `pip show mypackage` to see the list of extras.
  2. 80% success Install the package without extras and manually add dependencies 
    `pip install mypackage` then `pip install dependency1 dependency2` (as listed in the package's documentation).

Dead Ends

Common approaches that don't work:

  1. Assuming the extra is misspelled and trying random variations 70% fail

    Without knowing the correct extra name, guesses are unlikely to succeed.

  2. Installing the package without the extra 30% fail

    This may miss required dependencies for the desired functionality.
