根因分析
requirements.txt 中的拼写错误使用了 `=>` 而不是 `>=` 或 `==`。pip 的需求解析器拒绝了这个格式错误的版本说明符。
English
A typo in requirements.txt uses `=>` instead of `>=` or `==`. pip's requirement parser rejects the malformed version specifier.
解决方案
-
95% 成功率
Fix the operator in requirements.txt: sed -i 's/=>/>=/g' requirements.txt pip install -r requirements.txt
-
85% 成功率
Validate requirements before install: python -m pip install --dry-run -r requirements.txt
无效尝试
常见但无效的做法:
-
90% 失败
The parse error occurs before dependency resolution; --no-deps does not bypass parsing.
-
90% 失败
Upgrade flag does not change parsing; the same line fails.
