pip错误：'utf-8' codec can't decode byte解决方法

windows下python3.6安装flask时报错：

Exception:
Traceback (most recent call last):
  File "d:\python36\python36\lib\site-packages\pip\compat\__init__.py", line 73, in console_to_str
    return s.decode(sys.__stdout__.encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd5 in position 2: invalid continuation byte

原因是windows下命令行的代码页为GBK编码而非GBK。

解决方法：
找到报错文件，即python安装目录下\Lib\site-packages\pip\compat的__init__.py，文件中约75行

def console_to_str(s):
    try:
        return s.decode(sys.__stdout__.encoding)
    except UnicodeDecodeError:
        return s.decode('utf-8')

将’utf-8’修改为’gbk’即可
