【问题描述】：
每当我尝试运行pipenv 时，什么都没有发生。这是我的python和pip版本：
>> python -V
Python 2.7.18
>>pip -V
pip 20.1.1 from c:\program files\python27\lib\site-packages\pip (python 2.7)
我已成功安装pipenv：
>>pip install pipenv
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
Defaulting to user installation because normal site-packages is not writeable

pipenv 在我的 PATH 中找到并执行，但它实际上除了在我的控制台中输出一个空行之外没有做任何事情：
>>pipenv -V
>>pipenv install
>>pipenv lock --clean
>>
我使用的是 Windows 10 专业版：2004，操作系统版本：19041.329
