Hi everybody,
I joined this group to learn more about web development. I am familiar with Java, C, HTML, and am actively learning CSS and Python. And I'm facing some issue! Can somebody 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!

Heroku dont know if you upgrade you pip or any modules from pip the error above tells you that the packad y can not be found that means heroku works with orlder version's then you.
