Why doesn't the Python world just copy CPAN and update it for Python? You can e.g. literally find stuff in CPAN with hundreds of dependencies -- which is a pain, but even that works.
At least CPAN testers? Please...
If Python people insist that there is only one way to do it -- and the answer is Python, then rewrite CPAN in Python. Copy stuff that works...
Specific? I already mentioned CPAN Testers. And that CPAN works... (I've seen people with years of Python experience that had problem doing simple things. Edit: Including uninstall of packages, which you mention.)
Edit: Here you see a result of CPAN Testers for a module with complex dependencies. Note statistics on where/how dependencies are run. Also click on a dependency icon to see the matrix of perl/os versions.
(I really didn't expect Python users to admit that anything in any other environment could be better... :-) E.g. running tests at install by default is obviously bad? :-) )
So no comment about CPAN Testers -- automatically installing dependencies, running the test suites on different perl/os versions and then getting neat reports? What is the better way in Python?
