使用pipenv -h和其他命令--venv -install，UnicodeDecodeError：'utf-8'，pipenv命令出错，而我在其他地方找不到答案。

F:\proc_py\pipEnv>pipenv -h

我不知道为什么，pipenv命令出错。在其他地方找不到答案。

我遇到了同样的问题，并且潜伏在互联网上寻求解决方案，但是时间不多，并想出了一些可行的解决方法

我正在尝试通过Pycharm解释器设置来安装PIPEnvironment，并且出现了问题：

Failed creating virtual environment

    line = line.decode(encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcf in position 280: invalid continuation byte

我去了文件

“ C：\ Users \ ogmamedo \ AppData \ Roaming \ Python \ Python37 \ site-packages \ virtualenv.py”

并更改了这样的代码：

encoding = sys.getdefaultencoding()
fs_encoding = 'OEM' #sys.getfilesystemencoding()

这有助于我在发生错误时通过该阶段（前10秒）。

为什么是“ OEM”？因为正如我们在该文件中所看到的-调用了系统提示符（cmd shell），并且我系统的cmd shell编码为“ OEM”。

我会指出这是一种解决方法，而不是适当的解决方案，但是由于缺乏时间和兴趣，我无法确定此错误属于哪方面（pycharm或pipenv），继续寻求适当的解决方案。

使用pipenv -h，UnicodeDecodeError：'utf-8'
