pipenv install error UnicodeDecodeError: 'utf8' codec can't decode byte 0xb4 in position

看了https://www.jianshu.com/p/d08a4aa0008e这篇文章后对pipenv跃跃欲试，结果在执行 pipenv install 的时候就报错了.

-> pipenv install

错误是从其他博客复制过来的，报错内容是一样的，解决方案却不一样，原博主是修改源码，我这里是想起之前自定义过pip.ini文件来设置国内源，问题就出在这里，我是用win10的记事本来创建的pip.ini文件，总所周知，记事本保存的默认编码就是GBK，这里用VSCODE把这个文件保存为utf-8编码，保存后关闭VSCODE再次执行pipenv install命令即可.(注意pip.ini文件里不要写#注释，否则报错)

不要问我为什么要复制别人的错误，因为我无法复现，我尝试过把pip.ini的编码再改成GBK,结果保存后再打开又会变成utf-8。所以只好复制别人的错误了
