我最近为所有用户重新安装了Python，现在我在尝试运行pipenv install时遇到了这个问题。为什么会这样？

Python 3.5在path中。在前面的命令之后立即运行：

C:\Users\danie01\fox\test\robotframework>echo %PATH%
C:\Program Files\Python 3.5\;C:\Program Files\Python 3.5\Scripts\;blahblah

C:\Users\danie01\fox\test\robotframework>pipenv run python --version
Python 3.5.0

Answer 1

最近，当我从3.5转移到3.7.3时，我也遇到了同样的问题：

• 我删除了3.5，安装了3.7.3
• 从path中删除早期版本的python
• 更新的pipfile指向python的更新版本。
• 重新启动终端
• 重新安装pip：https://www.liquidweb.com/kb/install-pip-windows/
• 重新安装pip install pipenv

那么您应该可以运行pipenv install了。
