windows 10 上python3.6在CMD上使用pip list时出现如下错误：

UnicodeDecodeError: 'gbk' codec can't decode byte 0x90 in position 101: illegal multibyte sequence

pip命令均会出现这个错误。网上找到大多是python2的，使用sys.setdefaultencoding()来修改，但在python3中并没有这个，而且把CMD的编码改成65001(utf-8)还是没用。

Answer 1

修改
%APPDATA%pippip.ini
编码为ACSI编码.亲试有用。
