During the current brownout period, with the default use of pip, you get no error at all when you attempt to upgrade a package - it just says you're up to date - this (below) is the full output: $ python -m pip install -U pip Requirement already up-to-date: pip in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages You are using pip version 9.0.1, however version 9.0.3 is available. You should consider upgrading via the 'pip install --upgrade pip' command. Of course, it's very easy to miss that you don't have the latest version of the package in this case - everything looks like it worked correctly. If you try and install a package, it just says it can't find it, but not why: $ pip3.5 install transforms3d Collecting transforms3d Could not find a version that satisfies the requirement transforms3d (from versions: ) No matching distribution found for transforms3d You are using pip version 9.0.1, however version 9.0.3 is available. You should consider upgrading via the 'pip install --upgrade pip' command. You do get an informative message if you use the -v flag, but I rarely do that myself, and it's not the default. Just to give you an index of the problem, I got pretty confused myself when I asked pip to upgrade a package, it said it was already up to date, and I found I didn't have what I knew to be the right version, and I'm a very experienced pip user, who is also on various mailing lists where this was flagged.
