When deployed to Heroku, python setup.py egg info did not run successfully.

hi everybody,

I joined this group to learn more about web development. I'm familiar with Java, C, and HTML, and am actively learning CSS and Python. I am highly interested in programming, so I set a goal for myself to learn Python. And I'm facing some issues! Can someone help me?

After deploying and hosting my website, I upgraded my pip version. Then I installed the pypaystack package. When I try to push to Heroku, I get the error shown below. In the development stage, the project is running smoothly.

What can be the issue? I even created a new virtual environment but the error remains.

I'm hoping that this community will assist me on my path.
Thanks!
