我一直在试图找出导致此错误的原因，但是我尝试过的每一个解决方案，从完全卸载 python 和 pip 到 rm-ing 某些文件夹都不起作用：

答案1
rm -rf /usr/lib/python3.7/site-packages
python3.7 -m 确保pip
pip 安装--升级 pip
您需要删除 pip 包，而不是 site-packages 中所有已安装的包
答案2
看来我的主目录中的 python 已损坏。
因为我有 anaconda 环境，
我只是使用以下命令将其从我的用户目录中删除：
rm -rf /home/myusername/.local/lib/python3.6/
然后pip在某些 anaconda 环境中运行将解析为 anaconda 环境中的 pip。
