Ah, didn't know that. Thanks. [...] >> How do you know which version of Python `pip install foo` will use? How >> do I choose the version pip will install into?

That gets > around those problems. If you google for installation instructions, they're nearly always given in terms of "use pip", not "use python3.4 -m pip". My point isn't that there is *no* solution to this problem, but that its not necessarily an *obvious* solution. [...] >> How do I deal with permissions errors?

Last time I tried, I just got an uninformative error that the package installation failed. Admittedly that was probably a year or two ago, so maybe the error message has been improved. > How > do you deal with it? First you recognize that there's a problem. Nothing > in this thread suggested that there were perms problems to deal with. Indeed. For somebody who claims to be such an experienced developer, Bart is sure dedicated to the ideas that: 1. you ought to be able to install software without knowing anything at all about the operating system, the software being installed, or the installer. 2. If you run into an installation problem, it means the programming language sucks, not that you've done something wrong. 3. And you absolutely *shouldn't* ask for help or give sufficient details of what went wrong to allow others to diagnose the fault. Instead you should just *hint* at the error and make it out to be a systematic problem with the language itself. "Make it easy to install it" -- I'm 100% in agreement with that. "A literal brain-damaged monkey in a coma should be able to install it" -- not so much. -- Steve -- https://mail.python.org/mailman/listinfo/python-list
