Failed to create virtual environment.

当我在macOS pipenv shell中使用Mojave时，一切都还好，现在我正在使用Catalina version 10.15.1，但根本无法正常工作。我曾尝试升级pip，删除并重新安装pipenv，但同样的事情也会发生。：'（

有人可以帮我解决这个问题吗？

P.S。我想使用pipenv shell而不是python -m venv

的虚拟环境

Answer 1

pipenv似乎崩溃了，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`

如果由于pipenv抱怨没有关联的virtualenv而失败，则您必须跳过快捷方式，查看错误消息中不喜欢的文件夹，然后将其删除（确保删除了一个/virtualenvs的子文件夹，而不是重要的东西，例如pipenv bin）

例如，在这里您将执行以下操作：

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

Answer 2

使用@arshbot 提供的解决方案，我做到了：

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

Answer 3

删除virtualenv，帮助我解决了这个问题。我认为存在一些内部冲突。

pip uninstall virtualenv
