ModuleNotFoundError when installing a package with entry points using pipx

I'm writing a python package that I would like to distribute as a standalone terminal app. The structure of the project folder is the following:

energy-monitor/-- config/-- doc/-- tests/-- energymonitor/---- init.py -> (empty)---- main.py -> def main()---- data/---- ..other packages..-- project.toml

I'm using setuptools to generate a .tar.gz archive, some relevant parts of the project.toml file are:

    
[build-system]
requires = ["setuptools>=68.0"]
build-backend = "setuptools.build_meta"

[project]
name = "energy-monitor"
version = "0.0.1"

...

[tool.setuptools.packages.find]
where = ["energymonitor"]

[tool.setuptools.package-data]
data = ["data/*"]

[project.scripts]
energy-monitor = "energymonitor.main:main"


  

I generate the .tar.gz and the .whl files with the command python -m build, then I run pipx install path/to/energy-monitor.tar.gz. The installation is succesful, but when calling energy-monitor from the command line I get:

    
Traceback (most recent call last):
  File "/home/mattia/.local/bin/energy-monitor", line 5, in <module>
    from energymonitor.main import main
ModuleNotFoundError: No module named 'energymonitor'


  

Why is this happening? I was not able to find any helpful solution online. It's the first that I build a python package so sorry if the issue is trivial.

• python version: 3.11.3
