版本状态引入弃用备注
setuptools>=64 active — — —

根因分析

setuptools 在 v64 中移除了 `develop` 命令。在现代 setuptools 上运行 `python setup.py develop` 会失败，因为命令类已不存在。

English

setuptools removed the `develop` command in v64. Running `python setup.py develop` on modern setuptools fails because the command class no longer exists.

解决方案

  1. 95% 成功率 
    Use pip's editable install instead:

pip install -e .

This uses PEP 660 editable wheels and works with modern setuptools/hatchling/flit.
  2. 70% 成功率 
    For legacy projects that must run setup.py directly, invoke build_editable via the backend:

python -m build --wheel --no-isolation
pip install dist/mypackage-*.whl
# or with the PEP 660 hook:
python -c "from setuptools import build_meta; build_meta.build_editable('/tmp/out')"

无效尝试

常见但无效的做法:

  1. 70% 失败

    Downgrading setuptools globally breaks other packages that require newer setuptools features and is not a sustainable fix.

  2. 95% 失败

    The --user flag does not resurrect the removed command; the error is the same.
