vscode执行pip指令出现code for hash md5 was not found报错
问题描述
刚开始学习Python，为了图个方便就在vscode上安装Python插件直接写文件了，在执行pip install openpyxl的时候出现报错：code for hash md5 was not found报错。
问题出现的平台版本及自己尝试过哪些方法
MacOS 10.15.3
vscode 1.42.2
2020.05.07更新：
从终端看已经安装了python3和pip3，但是Mac自带python2，我不清楚现在到底是哪个版本在工作。
在终端尝试pip3 install openpyxl没有报错，但是显示需要通过pip install --upgrade pip升级pip，当然如果执行pip指令还是不能识别，于是我尝试了pip3 install --upgrade pip下载到8%出现报错：

你期待的结果是什么？实际看到的错误信息又是什么？
有没有大神指点下怎么能够正常的使用pip指令，谢谢！
回答：
看了下这个库要求的python版本是 3.6以上， 所以你先装个python3.x的版本再试看看吧
