根因分析

两个需求条目使用同一项目名称的不同拼写（连字符与下划线、大小写），pip 将它们规范化为一个名称后视为自冲突。

English

Two requirement entries use different spellings of the same project name (hyphen vs underscore, case), which pip normalizes to one name and then sees as a self-conflict.

解决方案

  1. 95% 成功率 
    # Replace underscores with hyphens and lowercase everything
sed -i 's/my_pkg/my-pkg/g' requirements.txt
python -m pip install -r requirements.txt
  2. 92% 成功率 
    python - <<'PY'
from packaging.utils import canonicalize_name
for n in ['my_pkg', 'My-Pkg', 'my.pkg']:
    print(n, '->', canonicalize_name(n))

无效尝试

常见但无效的做法:

  1. 85% 失败

    Installs the same project twice, with one overwriting the other's files.

  2. 80% 失败

    If both names appear in requirements, the conflict recurs on the next install.
