pipenv shell我在 macOS 下使用时一切正常Mojave，现在使用时Catalina version 10.15.1根本无法使用。我尝试过升级 pip、删除并重新安装 pipelinenv，但还是发生了同样的事情。:\'(

谁能帮我解决这个问题吗？

PS我想使用虚拟环境pipenv shell，而不是python -m venv

Answer 1

它似乎pipenv崩溃了，因为它尝试创建一个已经存在的文件夹。尝试清除虚拟环境

rm -rf `pipenv --venv`

如果由于 Pipenv 抱怨没有关联的 virtualenv 而失败，您将必须跳过快捷方式并查看错误消息以查找它不喜欢的文件夹并将其删除（确保您删除的是 的子文件夹/virtualenvs）不是像 pipenv bin 这样重要的东西）

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

删除 virtualenv 帮助我解决了这样的问题。我认为有一些内部冲突。

pip uninstall virtualenv
