Root Cause

The downloaded package hash does not match the hash specified in a requirements file with --hash constraints.

generic

中文

下载的包哈希与带有--hash约束的requirements文件中指定的哈希不匹配。

Workarounds

  1. 90% success Update hashes in requirements file 
    pip hash package.whl
# Update the hash in requirements.txt
  2. 85% success Regenerate requirements file with hashes 
    pip freeze --hash > requirements.txt

Dead Ends

Common approaches that don't work:

  1. Ignoring hashes with --no-hash-check 40% fail

    Bypasses security checks; may install malicious package.

  2. Re-downloading the same package 80% fail

    Hash mismatch persists if package was updated on server.
