[Package Issue Report]: poetry

[markjoshwel]

Are you requesting a new package or reporting an issue on an existing one?

This is an issue with an existing package: poetry

What changes are you requesting?

Running poetry shell throws the error "Unable to detect the current shell."
Running commands through poetry run still work.

I had just previously updated my devbox from 'devbox-0.5.2' to 'devbox-0.5.11'.
After which, it told me my devbox.json was outdated, so I ran devbox update

Before the update, poetry shell worked as expected.

• Output when not using devbox (expected)

Hey @markjoshwel, I've been trying to reproduce this, but haven't managed to get the same error. This seems like it might be related to your PATH or SHELL being misconfigured, based on the issues I've seen in the Poetry repo

Can you share what shell you are using, and what the value of the $SHELL env variable in your devbox shell is?

[markjoshwel]

I'm on Alpine Linux so i'm using the busybox variant of ash.

csp:~/works/surplus$ ls $SHELL
/bin/ash
csp:~/works/surplus$ devbox shell
Starting a devbox shell...
(devbox) csp:~/works/surplus$ echo $SHELL

(devbox) csp:~/works/surplus$

Seems like the variable becomes empty inside the devbox shell.

Also here's the output of devbox shell --print-env for good measure in case it might be useful for you:

Seems like my issue only arises after I update devbox.json.

I tried opening a devbox shell on an older project and was successful:

csp:~/works/surplus-enduser$ devbox shell
Warning: Your devbox.json contains packages in legacy format. Please run `devbox update` to update your devbox.json.
Ensuring packages are installed.

But I then updated my devbox.json:

$ devbox update

python NOTES:
python on devbox works best when used with a virtual environment (vent, virtualenv, etc). For example with python3:

> python -m venv .venv
> source .venv/bin/activate

Package managers like poetry (https://python-poetry.org/) automatically create virtual environments for you.

To show this information, run `devbox info python311`

poetry NOTES:
This plugin automatically configures poetry to use the version of python installed in your Devbox shell, instead of the Python version that it is bundled with.

This plugin sets the following environment variables:
* POETRY_VIRTUALENVS_IN_PROJECT=true
* POETRY_VIRTUALENVS_CREATE=true
* POETRY_VIRTUALENVS_PATH=/home/m/works/surplus-enduser/.devbox/virtenv/poetry/.virtualenvs

To show this information, run `devbox info poetry`

Info: Running "nix flake update"

After updating the devbox.json, I then exited any shells I was in opened a new devbox shell:

$ devbox shell
Starting a devbox shell...

Hey @Lagoja! I think I've possibly cracked the issue.

In a previous comment I show the output of devbox shell --print-env which shows that the shell environment variable is set:

...
export propagatedNativeBuildInputs="";
export shell="/nix/store/r4vxljid3iq94jp7qvd639sps0fscwy3-bash-5.2-p15/bin/bash";
export shellHook="";
...

And only now it struck me while setting up another project that it could be a case sensitivity issue!

csp:~/works/daycircle$ echo -e "SHELL=$SHELL\nshell=$shell"
SHELL=/bin/ash
shell=
csp:~/works/daycircle$ devbox shell
Starting a devbox shell...
(devbox) csp:~/works/daycircle$ echo -e "SHELL=$SHELL\nshell=$shell"
SHELL=
shell=/nix/store/vqvj60h076bhqj6977caz0pfxs6543nb-bash-5.2-p15/bin/bash

Lo and behold, after setting SHELL to the value of shell set by devbox, it works!

csp:~/works/daycircle$ devbox shell
Starting a devbox shell...
(devbox) csp:~/works/daycircle$ poetry shell

Spawning shell within /home/m/works/daycircle/.venv
bash-5.2$ . /home/m/works/daycircle/.venv/bin/activate

In any case, initialising the devbox shell should've also set the uppercase SHELL variable, but didn't until now. This could be a fault of poetry for not accounting for the lowercase variant, but it might not just be poetry!

Got it, that looks like a bug -- thank you for catching! I think we should be setting the SHELL variable instead of shell. I'll add this to our list to address for an upcoming release
