Pip and gem don't install multiple versions of the same package in deps folders like npm. You need to pin your versions. Installing a package does not normally trigger a neverending cascade of dependencies like it does with npm, cargo or go.
Npm is worse in every way because it doesn't even enforce documentation be shipped with the package nor does it provide easy means to do so like Perl pods or Python docstrings or docs. The result is that most modules do not come with any docs or if they do, each and every one uses its own structure and tools contributing to the general mess.
