I don't know what to tell you; I just gave an example of it being functional for a subset of users, who don't deserve to be broken just because it's non-functional on PyPI.

Nobody wants anything to be user-unfriendly. You're taking a very small view into Python packaging and extending it to motives, when resources (not even financial ones) are the primary challenge.

View on HN

Is code to detect when the user is not in that subset and say that it doesn't work really really hard for some non-obvious reason? If the default case for the vast majority of users doesn't work, it doesn't seem like printing a more useful error message to them should be that hard.

I think the existing error message is useful:

    $ pip search foo
    ERROR: XMLRPC request failed [code: -32500]
    RuntimeError: PyPI no longer supports 'pip search' (or XML-RPC search). Please use https://pypi.org/search (via a browser) instead. See https://warehouse.pypa.io/api-reference/xml-rpc.html#deprecated-methods for more information.

It says (1) what failed, (2) why it failed, and (3) links to a replacement, and (4) links to a deprecation explanation. That last link could maybe then link back to the pip issue or include some more context, but it's a far cry from being not helpful.

That is a nicer message than I remember. I don't have an issue with that. It let's you know it doesn't work, that it will never work, and provides links to an alternative and more information.

It either used to do fewer of those, or my memory is Swiss cheese, but I remember needing to search for the why's and alternatives.

There was a period when the error was a stack trace. But that was pretty brief, and happened before PyPI moved more "officially" towards not supporting the search API.

I think part of the confusion here (which is reasonable IMO) is that pip has a huge version tail, and so people report error messages and behaviors that have been fixed for years. This is one of the challenges that I think gets under-appreciated about pip's maintenance.
