在python上创建virtualenv时，我有一个警告：＆＃34;看起来pew不在你的PATH＆＃34;

Question

我在Windows 10环境中使用Python 3.6.3 我按顺序执行：

py -m pip install virtualenv
py -m pip install pew
py -m pip install pipenv

然后：

py -m pipenv --three

结果是

Creating a virtualenv for this project…
Using C:\Users\xxxx\AppData\Local\Programs\Python\Python36-32\python.exe to create virtualenv…
Warning: it looks like pew is not in your PATH. We cannot continue until this is resolved.

我尝试了下面的解决方案，但它不起作用： pipenv install gives "pew is not in your PATH"
