Root Cause

The --extra-index-url flag was used without providing a URL value.

generic

中文

使用了 --extra-index-url 标志但未提供 URL 值。

Workarounds

  1. 95% success 
    pip install package --extra-index-url https://private-pypi.example.com/simple
  2. 90% success 
    export PIP_EXTRA_INDEX_URL=https://private-pypi.example.com/simple && pip install package

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Pip will try to use that URL and fail to connect.

  2. 50% fail

    The package may not be found without the extra index.
