run my script in a spefic version or any later one

[snippsat]

how do i tell someone how to install from my server?

The simplest way is just to have wheel on server then give link to that file.
Just like i did in post over,so if you or anyone else download Life 1.0 the the only instruction is to install is this.
This work on all OS.

pip install Life-1.0.0-py3-none-any.whl

The other way is to run own PyPi sever,the have to search for setup own PyPi server .
