Root Cause

The requirements.txt contains an invalid syntax with a space between the package name and brackets for extras, or uses '=' instead of '==', causing pip to fail parsing.

generic

中文

requirements.txt 包含无效语法，包名和 extras 方括号之间有空格，或使用了 '=' 而不是 '=='，导致 pip 解析失败。

Workarounds

  1. 95% success Fix the syntax: remove spaces and use correct operator. Change 'package [extra1, extra2]' to 'package[extra1,extra2]' and ensure version specifier uses '==' not '='.

中文步骤

  1. 修复语法：移除空格并使用正确运算符。将 'package [extra1, extra2]' 改为 'package[extra1,extra2]'，并确保版本说明符使用 '==' 而不是 '='。
  2. 使用 pip 的解析功能进行验证：'pip install --dry-run -r requirements.txt' 以在完全安装前捕获语法错误。
  3. 手动安装后使用 'pip freeze' 重新生成 requirements.txt 以避免语法问题。

Dead Ends

Common approaches that don't work:

  1. 99% fail

    Adding a comment to requirements.txt does not fix the syntax error.

  2. 95% fail

    Running 'pip install --upgrade pip' does not change parsing rules; the syntax is still invalid.

  3. 98% fail

    Using 'pip install -r requirements.txt --ignore-requires-python' ignores Python version checks but not syntax errors.
