I have created the setup.py, toml file and the module properly. But after installation I am not able to run the module

Question

I have created a reproducable project.

https://github.com/sagarpadiya6/python_cli

I am trying to create a simple CLI application and I am trying to install it as a cli tool. But the installation is success when I run the install.sh

But after that when I try to run the flight_price command I am getting command not found. For some reason its not registering the cli tool at all.

I am using macos. And I have python 3.9 installed using brew.

The install.sh script has the following line

pip3 install -e .

Here is my setup.py file.

#!/usr/bin/env python

from setuptools import setup

setup(
    name='flight_price',
    version='0.0.1',
    packages=['flight_price'],
    install_requires=[
        'click',
        'importlib-metadata; python_version == "3.9"',
    ],
    entry_points={
        'console_scripts': [
            'flight_price = flight_price.__main__:main',
        ]
    }
)
