ERROR: Could not find a version that satisfies the requirement python3-dev (from versions: none)
初步认为是pip版本太低导致无法查询到
pip --version
发现版本为21.3.1
pip 21.3.1 from f:\anaconda3\lib\site-packages\pip-21.3.1-py3.7.egg\pip (python 3.7)
更新一下
easy_install --upgrade pip
结果
WARNING: The easy_install command is deprecated and will be removed in a future version.

看了一下其他资料，也许这个包名不是python3-dev呢？
或许是python-dev，说试就试！
