除了安装，其他pip2命令，如pip2 --version pip2 list 这些都能正常使用，一开始以为是pip2版本不够新，但是查了一下，我的20.3.4应该就是最新的了，我队友也能正常使用pip2安装包，他环境跟我差不多，都是20.3.4，用户名中文，我的无论安什么都报错。百度搜到的回答都不管用，还以为是不是之前python安装出了什么问题，重装从2.7.18换了一个2.7.9，但是依旧没有解决问题，中文路径也不是原因，希望能有师傅能帮忙解决一下。
pip的安装方法是从官网下的包，python2 setup.py install 安装的（build我试过，但是python2.7.9可能太老了，没有这个命令，原来的2.7.18可以）。
试试能不能升级 pip
python2 -m pip install --upgrade pip
