cannot find python in env when using `pipenv`

[mfts]

My setup is a repo with a pkgx.yaml file that defines dependencies

 dependencies: |
  pipenv.pypa.io@2023.9.1
  python@3.11
  node@20
  npm@10

when I cd into repo, env is set up as expected

...

Next, I pipenv shell I have a Pipefile already in the repo

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
tinybird-cli = "*"

[dev-packages]

[requires]
python_version = "3.11"

It activates the venv but when I try to update tinybird-cli package it throws an error

(venv) $ pipenv update tinybird-cli

The current solution is while the virtual env is active, cd .. && cd <repo> and then it works without the prior error.

(venv) $ pipenv update tinybird-cli

I'm not familiar enough with Python so cannot decode its error, what is the error line specicially and what does it mean? Thanks.

@mfts it would be interesting to see the difference between env output before the pipenv invocation, after, and again after the cd ..; cd -. i assume pipenv is crushing something in the devenv, which is restored when you reenter it.

I just tested this with new pip/pipenv and all the other fixes that must have happened since the report and it all works now!
