Question

我有一个现有项目，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，因此我将python（windows 64）升级到了3.7.4。在我的通常文件夹中运行pipenv shell时，出现以下消息：

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...

然后出现此错误：

Creating virtual environment...

Failed to create virtual environment.

我尝试在另一个先前的项目文件夹上运行pipenv shell，问题是相同的：安装我没有要求，并且在安装过程中卡住了。谢谢您的帮助！

我只是想用更新的python版本运行我通常的虚拟环境。

解决了它，这显然是virtualenv的问题。升级到16.6.2版本。

pip install virtualenv==16.6.2

为什么我的pipenv在python升级后消失了？
