随手记（报错）：
LookupError: setuptools-scm was unable to detect version for H:\fullnet\fullnet-main\fullnet-main.

Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

一种可能的报错原因是，本来是一个github项目，没有git clone到本地，而是直接打包到了本地，再直接安装。解决方法是git clone到本地，再用 python setup.py install 安装
