解决python安装包提示Could not install packages due to an EnvironmentError: [Errno 0]

问题是[Errno 0]，注意了。不是提示这个直接找下一个解决方案。

具体错误代码

|鈻ERROR: Could not install packages due to an EnvironmentError: [Errno 0]

需要设置set PYTHONIOENCODING=UTF-8的和提示需要LookupError: unknown encoding: cp65001后不要设置成utf-8

解决方案：

直接设置cmd成：chcp936

然后pip去安装

是否解决问题了？
