Font Bakery installation problems

Hi there,
I've tried to install Font Bakery under Big Sur but I can't go beyond the command:
pip3 install fontbakery
because the terminal will always return:
Killed: 9
Any idea on how to sort this out?
TIA.
R.

    Could you post an issue here and please include the full output of the pip command? I'll take a look.
  • No problem. FYI, "Killed: 9" is the full output.

    Urgh. Your Python installation is in a bad way.
  • What should I do then?
  • Warning: [email protected] 3.9.6 is already installed and up-to-date.
    Python seems to be installed but if I run 'pyhton3' or 'pip3' I always get a 'Killed: 9' :s

    "Killed: 9" is basically an out of memory error. But you shouldn't get one just from running pip. Can you try "which python3" to see if you're using the system Python or homebrew's?

    Have you tried installing FB in a Python virtual environment to minimise possible conflicts?
  • @Simon Cozens Yes, then I get:
    /Library/Frameworks/Python.framework/Versions/3.4/bin/python3

    So that's the system Python, which is even more concerning, since that *really* shouldn't be dying on you at the drop of a hat. I'd mitigate the problem by running "brew link [email protected]" to make Homebrew's Python into the one that is run at the command line, but something is sick with your OS installation.
  • FWIW, I think your current problem is caused by following advice like "brew link [email protected]" in the past: you have python 3.4 as system python, 3.9.x via homebrew (and installed under /usr/local/), and part of pip3 install could go under ~/.local/lib/python3.9 or ~/.local/lib/python3.4 , depending on whereher you ran 3.4's pip3 or 3.9's pip3.

    If it is not a fresh new machine, it is likely your pip3 expects stuff to be under ~/.local/lib/python3.8 or 3.7 or 3.3/3.2 too, from past installations.

    Mostly I would say stick with the system python, whichever version it is, unless you have a strong reason to do otherwise.

    As it is likely you have leftover python package bits associated with different version of python, and the solution is to examine and scrub all 3 locations (/Library/Frameworks/Python.framework/Versions , /usr/local, and ~/.local/ ) of dubious content.

    Signal 9 is sigkill, it being killed by something else or self-destruct. Memory access violation is sigsegv (segmentation fault, 11) but often it gets killed by a sigabrt (6) instead.

    I generally try to avoid homebrew. It always breaks after a while. On my office Mac, I installed a current version of vim via homebrew and now even that crashes on launch.

    And remember: “Homebrew Python Is Not For You

    I haven't had any problems with the Python installers from python.org. Many font-related Python modules now require Python 3.7+.
  • I second @Jens Kutilek 's suggestion: if you need higher python version that Apple ships, the python people have at least bothered enough to do their installer in the apple way.

    @Ramiro Espinoza I would suggest getting yourself signed up at github so you can ask for guidance at fontbakery's issue tracker directly. While the main developer of fontbakery is somewhat a diehard Linux-head, there are enough mac-centric devs there to help. 

    You have three locations to watch out for dubious content :

    1.  /Library/Frameworks/Python.framework/Versions

    where Apple put their stuff there . Generally you'd like to leave that alone; they should all have more or less the same time stamp (same as the age of your OS or your last OS upgrade) ; watch out for files substantially newer than the rest: that indicates you may have followed bad advice in the past to polute what is meant to be a apple-only location.

     2. /usr/local , where homebrew (and other more unix-like instructions) installs things . In general, if you don't like anything under there, you can remove it. On new installation, it has a few empty sub-directories. The worst thing that would happen is some new extra small software that you install yourself since you got your box needs reinstalling.

    3. ~/.local/ (or where per-user python stuff is installed) is a little more complicated. Perhaps you can start with posting the output of `du ~/.local/` , and if the output not too long `ls -lR ~/.local`. You may want to keep some of it so we need to know what is there first.

    There is one more place to clean: ~/.cache/pip/ (pip3 is just python 3 version of pip, when both python 2 and 3 are present). It is where pip keeps some cache files. It is safe to delete it all - whatever is missing and needed for the next run will be downloaded again . Cleaning it out might be useful in case your problem is due to a previous corrupted / incomplete download which somehow wedges itself in, like a download that is broken but claims to be complete.
