尝试安装ordered set时出现UnicodeDecodeError

Question

我尝试通过pip、setup.py和使用轮子安装ordered-set，但这三次都得到了异常：

Exception:
Traceback (most recent call last):
  File "c:\python 3.6.3\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 0xcd in position 35: 
invalid continuation byte

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
 File "c:\python 3.6.3\lib\site-packages\pip\basecommand.py", line 215, in main 
status = self.run(options, args)

return s.decode('utf_8')

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcd in position 35: 
invalid continuation byte

它可以依赖于什么？我该怎么做才能解决这个问题？

我在安装stix和cybox包时遇到了同样的问题。

Answer 1

尝试将pip更新为测试版pip install -U --pre pip

如果没有帮助，请尝试使用easy_install

另一种解决方案：

运行一个新的cmd.exe控制台chcp，它将显示系统默认代码，例如936。在75行左右打开Lib/site-package/pip/compat/init.py，将返回s.decode('utf_8')改为返回s.decode('cp936')

这只是https://github.com/pypa/pip/issues/4251的一个变通方法
