pipenv shell无法创建虚拟环境

Question

我想使用pipenv shell运行一个Django项目。但是当我输入pipenv shell命令时，它失败了。

Failed to create virtual environment.

在使用macOS Mojave时，我使用pipenv shell一切都正常，现在我使用的是Catalina版本10.15.1，但是完全不起作用。我尝试过升级pip、删除和重新安装pipenv，但仍然出现同样的问题。有没有人能帮我解决这个问题呢？

附言：我想使用pipenv shell虚拟环境，而不是python -m venv。

Answer 1

看起来 pipenv 崩溃了，因为它试图创建一个已经存在的文件夹。尝试使用清除虚拟环境：

rm -rf `pipenv --venv`

如果这种方法失败了，因为pipenv抱怨没有关联的虚拟环境，那么您将不得不跳过快捷方式并查看错误消息以了解它不喜欢哪个文件夹，然后删除它（确保您正在删除 /virtualenvs 的子文件夹而不是像pipenv bin这样重要的东西）。

例如，在这里，您需要执行以下操作：

rm -rf /Users/juyeong/.local/share/virtualenvs/django_workspace-CfQ2tbWB/

非常感谢，但它说： “此项目尚未创建虚拟环境！ 已中止！” - Judy

一些原因导致pipenv停止跟踪与您的项目相关的虚拟环境，但它仍然存在。请使用rm -rf /Users/juyeong/.local/share/virtualenvs/django_workspace-CfQ2tbWB/手动删除它。 - arshbot

现在它可以运行了！非常感谢你所有的帮助。 :) - Judy

这对我有用 - 我也会在答案部分发布，以展示我的错误日志和解决方案... - nate

Answer 2

我移除了 virtualenv，这帮助我解决了这个问题。我认为可能存在一些内部冲突。

pip uninstall virtualenv

使用@arshbot提供的解决方案，我执行了以下操作：

rm -rf /Users/nathan.benton/.pyenv/versions/3.8.6/bin/python3.8
