zsh: /usr/local/bin/pipenv: bad interpreter: /usr/local/opt/python/bin/python3.7: no such file or directory

Question

I recently switched from bash to zsh (MacOS). I haven't used pipenv since the switch. Now when I run any pipenv command I get the following error:

$ pipenv install
zsh: /usr/local/bin/pipenv: bad interpreter: /usr/local/opt/python/bin/python3.7: no such file or directory

I use pyenv for Python dependency management:

$ which python
/Users/ryan.payne/.pyenv/shims/python

My default python version is 3.7.3:

$ pyenv versions
  system
  2.7.16
  3.6.8
* 3.7.3 (set by /Users/ryan.payne/.pyenv/version)

It seems like pipenv is not using my pyenv version of Python. How do I get pipenv working again?

Solution 1

I had this same error with awscli. The solution was to install [email protected] via homebrew and then cp that installation into the directory awscli expected.

brew install [email protected]
cp -r /usr/local/opt/[email protected]/bin/python3.7 /usr/local/opt/python/bin/python3.7

Solution 2

You don't need to uninstall anything. Simply change the interpreter at /usr/local/bin and have your current python path in pyenv handy:

type python3

copy the path

vi /usr/local/bin/pipenv

It will look something like this:

Once it's changed, you will probably have to download pipenv again. Don't worry, your env is fine.

pip install pipenv

Go play in your env

Solution 3

Run in terminal:

brew install python3 && cp /usr/local/bin/python3 /usr/local/bin/python

"Bad interpreter" means exactly what it says. Check the first line of the script that fails for the "shebang" -- the specification of what interpreter is to be used to run that script. Make sure that shebang points to an interpreter that actually exists.

...if you want it to traverse your PATH to find a copy of python to use (and thus, to use the same one which finds), then you need it to start with #!/usr/bin/env python; whereas right now it presumably starts with #!/usr/local/opt/python/bin/python3.7, which the error message indicates doesn't exist or is missing runtime dependencies..

I had the same problem with black on mac after brew upgrade. The similar procedure worked for me. Thnx

I had python3 already installed so I just ran this command and it worked : cp /usr/local/bin/python3 /usr/local/bin/python
