Let's say I have a package MyPackage hosted on Pypi with two versions: 1.0 and 2.0
When a user runs the command pip install MyPackage I want them to download and install 1.0.
Is it possible to set a default/recommended package version in this manner?
I want to stray away from doing any beta releases i.e. 2.0b1
No, this is not possible. pip install MyPackage will always install the highest available version of MyPackage, excluding prelease ("beta") versions unless the --pre flag is given. There are no provisions anywhere in the packaging system for it to do anything else.
