在 `pipenv install` 之后使用 `pipenv shell` 会产生“UNKNOWN_VIRTUAL_ENVIRONMENT 的 Shell 已经激活。”

Question

When I first install packages to a virtual environment with pipenv install package and secondly try to open a subshell to operate in that environment with pipenv shell i receive the following:

"Shell for UNKNOWN_VIRTUAL_ENVIRONMENT already activated. No action taken to avoid nested environments."

However, which python returns the file path of the system python, which indicated that actually the virtual environment is not activated.

ctr+D and recalling pipenv shell finally opens a subshell within the virtual environment. Can someone explain me what's going on there? Honestly, I am severely conufused.

Answer 1

just cd to the folder that has your venv (.venv, Pipfile, Pipfile.lock) and run exit. it will exit the folder and now you can again cd to the same folder and use pipenv shell. it will work

Answer 2

Exit the shell using exit and NOT deactivate . As explained here , " deactivate will leave pipenv in a confused state because you will still be in that spawned shell instance but not in an activated virtualenv."

Once you exit properly, you can navigate back to the directory and use pipenv shell
