Can not Install Ryu: AttributeError: module 'setuptools.command.easy_install' has no attribute 'get_script_args'

[faniAhmed]

I have been trying to install Ryu for few days but was not able to get around this error. I have been stuck for long and need to install it as soon as possible to continue working.

fani@fani-VMware-Virtual-Platform:~/ryu$ pip install . --break-system-packages

I had the same issue

Python 3.8.19
pip 24.2 from C:\mycodes\envs\python\lib\site-packages\pip (python 3.8)

Downgrading setuptools Solved my problem

pip uninstall setuptools
pip install setuptools==67.6.1
cd ryu, pip install .

Thank you
