Package directory does not exist

I'm trying to install python packages in COLAB using the following setup.py file.

from setuptools import setup

setup(
    name=gym_robot,
    version=0.3,
    url=https://github.com/zoraiz-ali/gym.git,
    author=Zoraiz Ali,
    license=MIT,
    packages=[gym_robot, gym_robot.envs, gym_robot.envs.helper, ],
    include_package_data=True,
    install_requires=[gym, numpy, opencv-python, pillow]
)

I execute the following command

! python /content/gym/setup.py install

This returns the following error

error: package directory 'gym_robot' does not exist

I do not find any solution, anyone knows how to install packages on Goole COlAB?
