Root Cause

The extra index URL requires authentication or is not accessible from the current network.

generic

中文

额外的索引 URL 需要身份验证或从当前网络无法访问。

Workarounds

  1. 85% success Provide credentials in the index URL 
    pip install --extra-index-url https://username:[email protected]/simple mypackage
  2. 90% success Use a .netrc file for authentication 
    echo 'machine private-pypi.example.com login username password password' >> ~/.netrc && chmod 600 ~/.netrc

Dead Ends

Common approaches that don't work:

  1. Using --trusted-host without credentials 80% fail

    Trusted-host only bypasses SSL verification, not authentication.

  2. Adding the URL to pip.conf without credentials 70% fail

    pip still needs authentication for private repositories.
