Issue

The current project could not be installed: No file/folder found for package api-meucx
If you do not want to install the current project use --no-root

how to reproduce:

poetry install

the error may be here:

what i tried to do:

• change the project name in pyproject.toml
• reinstall poetry
• reinstall project - delete and git clone again.
• change path name.

And do you have an api_meucx folder with Python files or an api_meucx.py in your project folder?

[m1guer]

no, its a django project.

[m1guer]

and the api_meucx is the base dir. inside have the poetry filess

[dimbleby]

what part of the message do you think is wrong?

[m1guer]

hmhmh None?

[dimbleby]

then please close the issue report

I don't understand what is going on here; I am sure my project used to work but now it doesn't. What does it mean - that I now have to have my source files in a sub-directory with the same name as my project?

[radoering]

That's just a warning. If your project used to work, it will probably still work despite of this warning. It means that you either have to make your project packageable or use --no-root.

Or ignore the warning for now and wait for #8650.

[ughstudios]

this is a weird error happening for me as well.

hi guys i've solved the problem renaming the project name in .toml_ to the project core folder.
dont use uppercase to the project folder name. and dont use special symbols like "-" or "_"

[mathewvaughan]

Facing a similar issue - just want to check my understanding. Here's my minimum repro:

• I create a directory called 'test', and I cd into it. (Imagine that this is the repo of a web service, not a library)

• I run poetry init and just accept all the defaults.

• I run poetry install.

• I see the following:

Installing the current project: test (0.1.0)
The current project could not be installed: No file/folder found for package test
If you do not want to install the current project use --no-root

I've not had this warning before - but to my understanding my root is the parent directory 'test' and this isn't being respected by the poetry install command?

Edits: Changed formatting for clarity

poetry init just creates the pyproject.toml. Read the docs for poetry new to get an idea of a valid project structure.

[gaoming714]

A common poetry project should have four part:
1 pyproject.toml 2 README.md 3 "projectName folder/ __init__.py " 4 tests

If you use poetry version, such as 1.4.0, poetry will not check these files.
the warning (No file/folder found for package) only show the missing part, but it will not affect to use poetry to run scripts.

[adriangay]

I upgraded from 1.4.1 to 1.7.1. requiring the folder in which you want to create a .venv to match the name in the toml file is a breaking change IMHO. Yes, I get the message is a warning.

[enlore]

I upgraded from 1.6 to 1.7.

I did not understand that this message is a warning. That is because it does not say "Warning" anywhere in the message.

Unhelpful.

➜  backend git:(main) poetry install
Installing dependencies from lock file

Installing the current project: src (0.1.0)
The current project could not be installed: No file/folder found for package src
If you do not want to install the current project use --no-root

[m1guer]

just create an folder with the name in pyproject.toml and put py file inside.

[m1guer]

pyproject.toml

__init__.py

[conoremclaughlin]

+1 to this being a breaking change - No explicit statement this is a warning causes a lot of worry, and we shouldn't have to require the name of the folder to match the name of the project. We may want the project name to be more descriptive vs the folder name in the case of monorepos.

[AlfredMoore]

I meet this warning because the folder name is different from the project name in 'pyproject.toml'

[ZachHandley]

Yeah so I don't know who is using pyproject.toml in their project root (e.g. outside the base folder, for instance I have my files inside api/ as FastAPI + Poetry is my API), but this just feels like an oversight to me. If it's a warning it shouldn't stop me from installing. Don't limit me based on the name of my package. NPM doesn't do this, so why in the world does Poetry feel like they need to be the first? It's hard enough to get Poetry setup, nevermind random warnings like this that don't seem to even have a point.

[m1guer]

your setup needs be like this:
project_name/
├── pyproject.toml
├── api/
│ ├── init.py
└── ...

I get it, I just also think don't tell me how to scaffold my projects or how they should be designed, it's not Poetry's job. Give me an entry point like Node / Bun.

[radoering]

I did not understand that this message is a warning. That is because it does not say "Warning" anywhere in the message.

In hindsight, we should probably have prefixed the message with Warning: and maybe even not printed the error inside the warning in red.

Unfortunately, it is Poetry's job to tell you if your project can't be packaged and thus not installed since Poetry is not only for dependency management but also for packaging. There are two opposite groups of users:

• Users complaining about the warning in this issue because they use Poetry only for dependency management
• Users complaining that the warning is not an error in poetry install exit code 0 (success) even if readme file does not exist and fails to install the package #8637 because they use Poetry for dependency management and packaging

All in all. #8662 (comment) still holds true. With #8650, you will have a means to silence this warning without always typing --no-root.

[ZachHandley]

@radoering I get that it is poetry's job to tell me if it can or can't be packaged, but this is not a packaging issue. My poetry project worked perfectly fine before requiring an asinine folder. If you want to fix this, include more details in the warning so people like me don't go wtf for an hour and a half and then come here because it was suddenly added. On top of that, the pyproject.toml could be used to find the root folder instead of some arbitrary requirement. Or maybe look for a src folder or allow an entrypoint???

Finally,

I added the __init__.py to my api folder (and my app folder has had one) and I still get the same error. Putting the pyproject.toml at my root folder doesn't make a ton of sense, as it's an API.

[finswimmer]

On top of that, the pyproject.toml could be used to find the root folder instead of some arbitrary requirement.

This is exactly what poetry does. If not specified explicit (https://python-poetry.org/docs/pyproject/#packages) Poetry will look for a folder with a normalized name of the project, that contains at least one .py file in the folder where the pyproject.toml is located or in a src folder.

[kyleshrader]

Can you provide configuration so that the project always installs as --no-root? Maybe private = true or something?

[AlexanderLanin]

@kyleshrader yes, see #8650

[AlexanderLanin]

FYI I encountered this problem today and --no-root is not what I wanted, as I did want to use poetry run with my scripts.

I cannot follow the standard directory structure, so what helped me is to define packages to point poetry to where my code actually is.

packages = [
    { include = "custom_components" },
    { include = "scripts" },
]

(It's a home assistant integration, therefore it has a fixed directory structure where the integration is in custom_components).

[Lamarcke]

I'm also facing this issue. The message doesn't come off as a "warning" at all.

[danisztls]

That's just a warning. If your project used to work, it will probably still work despite of this warning. It means that you either have to make your project packageable or use --no-root.

Or ignore the warning for now and wait for #8650.

First time I see warnings in bright red.

[radoering]

To be fair: The warning starts in yellow and ends in yellow, only part of it is red.

Nevertheless, the feedback makes it clear, that it's too confusing for many users if parts of a warning are printed in red. In the next release the warning will be prefixed with "Warning:" and printed completely in yellow.

For future reference: The change will be made in #8650 since it will change the text of the warning anyway.

Just to be clear: Even if it's fine to ignore the warning for now, you probably want to address it in the next Poetry release with #8650 because this warning will eventually become an error in a future release to resolve #8637.
