pipenv install命令创建python虚拟环境报错：UnicodeDecodeError: 'utf-8' codec can't decode
使用pipenv install命名创建python虚拟开发环境报错
在命名行输入：
pipenv install
创建python虚拟环境
发现报错了，报错信息如下：
$ pipenv install

在stackoverflow上看到了一个解决方法，测试后成功创建虚拟环境
具体方法如下：
在你的python 包安装路径下找到文件：（也可以通过报错信息找到文件路径）
F:\Python\Lib\site-packages\virtualenv.py
用文本编辑工具打开修改：
将第933、934行的（可能不是在933行，只要找到这两行代码就行）
encoding = sys.getdefaultencoding()
fs_encoding = sys.getfilesystemencoding()
修改为:
encoding = sys.getdefaultencoding()
fs_encoding = 'OEM' #sys.getfilesystemencoding()
即可。
然后再次命令行输入：
pipenv install
等待几秒后创建环境成功！
此解决方法未经多次测试，不具备普遍适用性！
