pipenv shell 创建虚拟环境失败

Question

我正在尝试运行使用 pipenv shell 的 Django 项目。但是当我输入命令pipenv shell时，它失败了。

Failed to create virtual environment.

当我在 macOS Mojave 中使用 pipenv shell 时一切正常，现在我使用 Catalina version 10.15.1 并且它根本不工作。我试过升级 pip，删除并重新安装 pipenv，但同样的事情发生了。 :'(

谁能帮我解决这个问题？

P.S。我想使用 pipenv shell 的虚拟环境，而不是 python -m venv

Answer 1

似乎 pipenv 正在崩溃，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`

如果因为 pipenv 抱怨没有关联的 virtualenv 而失败，你将不得不跳过快捷方式并查看它不喜欢的文件夹的错误消息并将其删除（确保你是删除 /virtualenvs 的子文件夹而不是像 pipenv bin )

这样重要的东西

例如，您可以执行以下操作：

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

Answer 2

使用@arshbot 提供的解决方案，我这样做了：

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

Answer 3

移除 virtualenv，帮我解决了这个问题。我认为存在一些内部冲突。

pip uninstall virtualenv
