Root Cause

The version specifier uses triple equals (===) which is not a valid operator in PEP 440; only ==, >=, <=, >, <, ~=, != are allowed.

generic

中文

版本说明符使用了三个等号（===），这不是 PEP 440 中的有效运算符；只允许 ==、>=、<=、>、<、~=、!=。

Workarounds

  1. 99% success 
    pip install package==1.0.0
  2. 90% success 
    pip install 'package~=1.0.0'
  3. 85% success 
    Refer to the packaging documentation for correct syntax.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Quoting does not fix the invalid operator.

  2. 95% fail

    Newer pip still enforces valid operators.

  3. 95% fail

    Force reinstall does not bypass parsing.
