poetry show gives a RunTimeError when not in the right directory

[ergut]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: MacOS Big Sur 11.4
• Poetry version: 1.1.13

Issue

When you run "poetry show" command outside a poetry directory we get a RunTimeError with the following tracking information. Wouldn't it be preferable to show an error message in this case and exit the program gracefully?

  RuntimeError

  Poetry could not find a pyproject.toml file in ... or its parents

      368│         else:

      372│                 )
      373│             )

For example, running git status on a non-git directory gives the following output:

fatal: not a git repository (or any of the parent directories): .git

This happens to me with every poetry command, when pyproject.toml is not present.
E.g. here is the output from 'poetry init', which should actually create the pyproject.toml if it doesn't exist already.

poetry 1.2.0b1 (installed via the new install-poetry.py installer)

poetry init -vvv

There are several open issues talking about the ugly output poetry gives on any error, #5559 looks like the furthest progressed try at doing something about it (and lists some duplicates).

[branchvincent]

This was fixed with #5766, and will be part of the upcoming 1.2 release. It now looks like:

$ poetry show

Poetry could not find a pyproject.toml file in /path/to/cwd or its parents

I have a question about this, if I may. Does this mean that it's necessary to change directory to the poetry project folder (where the pyproject.toml is) to execute the python code in that project? Isn't there any way to do so from outside that folder?

I'm pretty sure pipenv allows me to do something like pipenv run python3 /path/to/project/folder/script.py from another location.

Thanks a lot.

@msoutopico: Since Poetry 1.3 you can use the global parameter -C/--directory to point to the directory where the project is located.

-C, --directory=DIRECTORY  The working directory for the Poetry command (defaults to the current working directory).

Thanks a lot @finswimmer . I had tried that with poetry 1.3.1 but I might be doing something wrong. I do:

~ poetry --directory=$app_root run python foo.py

but that gives me "Poetry could not find a pyproject.toml file in /home/souto/ or its parents".

It does work however if I do:

~ cd $app_root && poetry run python foo.py && cd -                                                          

Could you give me any tip?

I hope this is a good place to ask. Apologies if it's not, in which case I'll try in Discord.
