Root Cause

The requirements file specifies a hash algorithm that pip does not support in the current version or environment. pip typically supports sha256, sha384, sha512, but older versions may not.

generic

中文

requirements 文件指定了 pip 在当前版本或环境中不支持的哈希算法。pip 通常支持 sha256、sha384、sha512，但旧版本可能不支持。

Workarounds

  1. 90% success 
    Upgrade pip to the latest version: python -m pip install --upgrade pip.
  2. 95% success 
    Change the hash algorithm to sha256 in requirements.txt, which is universally supported.

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Disables hash checking, reducing security and potentially allowing tampered packages.

  2. 90% fail

    Doesn't address the hash algorithm issue; still fails.
