Root Cause

Pip cannot authenticate to a private VCS repository; missing credentials or SSH keys.

generic

中文

pip无法验证到私有VCS仓库；缺少凭据或SSH密钥。

Workarounds

  1. 90% success Use SSH URL with SSH keys configured 
    pip install git+ssh://[email protected]/user/private-repo.git
  2. 85% success Use personal access token in URL 
    pip install git+https://<token>@github.com/user/private-repo.git

Dead Ends

Common approaches that don't work:

  1. Using --no-cache-dir 90% fail

    Cache is not the issue; authentication is required.

  2. Removing the package from requirements 60% fail

    Package is needed; removal breaks functionality.
