ModuleNotFoundError immediately after initializing a project #7622

Open 5183nischal opened 1 week ago

5183nischal commented 1 week ago

The following error occurs when I initialize a project under ~/Documents but not say under ~/Downloads (in macos).

  1. Initialize a new project using uv: I initialized a new project named trials using the uv command.

    uv init --lib trials

    Output:

    Initialized project `trials` at `/Users/nisch/Documents/trials`
  2. Navigate to the project directory: I changed the directory to the newly created trials project.

    cd trials
  3. Run Python command to import the trials module: I attempted to run a Python command to import the trials module using uv.

    uv run python -c "import trials"

    Output:

    Using Python 3.10.15
    Creating virtual environment at: .venv
       Built trials @ file:///Users/nisch/Documents/trials
    Installed 1 package in 1ms
  4. Run the same command again: I ran the same command again to import the trials module.

    uv run python -c "import trials"

    Output:

    Traceback (most recent call last):
     File "<string>", line 1, in <module>
    ModuleNotFoundError: No module named 'trials'

Issue

After initializing the project and running the command to import the trials module, I encountered a ModuleNotFoundError. It seems that the trials module is not being recognized, even though the project was initialized successfully.

Expected Behavior

The trials module should be importable after initializing the project and running the command.

Actual Behavior

The trials module is not found, resulting in a ModuleNotFoundError.

Verbose Output

I ran the command with the -v (verbose) flag to get more detailed output:

uv run -v python -c "import trials"

Verbose Output:

Thanks in advance!

:+1: I got this problem often as well

If you want the template project to be created with an importable directory like that you, consider using uv init trials --lib. By default, we create an --app, which just contains runnable scripts as opposed to a buildable project. \cc @zaneib

But I do initialize it with the --lib!

Oh sorry -- I missed that. I can't reproduce this though.

Yes, I can't reproduce this everywhere in my own computer either. Only when I'm under ~/Documents in my computer I get this error. Want to understand if you guys would have an idea why that might be happening.
