python升级后为什么我的pipenv消失了？

Question

我有一个现有的项目，一切都很好。由于 Heroku 似乎需要特定的 python 运行时版本进行部署，我将 python (windows 64) 升级到 3.7.4 在我常用的文件夹中运行 pipenv shell 时，我收到以下消息：

C:\Users\henry\Desktop\testldc>pipenv shell
Creating a virtualenv for this project…
Pipfile: C:\Users\henry\Desktop\testldc\Pipfile
Using c:\users\henry\appdata\local\programs\python\python37\python.exe 
(3.7.4) to create virtualenv…
[=== ] Creating virtual environment... 

然后我得到这个错误：

Creating virtual environment...

Failed to create virtual environment.

我尝试在另一个以前的项目文件夹上运行 pipenv shell，但问题是一样的：我没有要求安装，并且在安装过程中卡住了。感谢您的帮助！

我只是想用更新的 python 版本运行我常用的虚拟环境。

解决了，这显然是 virtualenv 的问题。 升级到 16.6.2 版本。

pip install virtualenv==16.6.2
