help me to understand the output of a package that is failing to build

mikey_effin_d! · 2020-08-26 15:25:06

in an effort to actually learn what is going wrong so i no longer need to hit the forums every time a package doesnt compile correctly, i would like to understand what is happening that is causing the package build to fail. ive been using linux for a while and have an entry level (but not brand new) understanding of bash and the basic terminal commands.

in this case i am trying to build a package from the AUR:
<yay -S python-num2words>

i know since this is a python package a basic understanding of python output is needed. my skills in python end at the ever so basic: print

HERE IS THE OUTPUT SUMMARY:

Please edit your post to add code tags around the commands / output. Then read the comments on the AUR page for this package.

if you just need the python3 version, remove the python2 package from the pkgname array and remove the python2 line in the check function.

SOLVED on my own. after paying closer attention to the output i noticed the build was failing due to the missing python-docopt, which i attempted to fix with yay -S python-docopt, only to see it was already installed. then i noted the notice about python 2 being discontinued so i hit it with a
yay -S python2-docopt && yay -S python-num2words
PROBLEM SOLVED. though im still interested in the breakdown of the output so i better understand whats going on

mikey_effin_d! · 2020-08-26 15:32:53

though it is a python3 package it had a python2 dependency

mikey_effin_d! · 2020-08-26 15:35:45

like whats up with all the error code exit 1. i see that a lot when packages fail to build. what does 1 mean. and after that all the f****** crap after:
command: /usr/bin/python2 <blah blah -blah --blah "blahblah" blah>

No, it is a split package that builds both a python2 and python3 package. The python2 dependencies are (should be) only build time dependencies. Again, this is all covered in the comments on the package's AUR page.

Sounds like you didn't bother reading the PKGBUILD

i can barely understand half of a PKGBUILD file. a super basic one is almost doable for me, but im not there yet. ive been on linux for about 5 years now. Ive settled down as an arch user and dont see myself going anywhere else even though its sometimes more advance then my skill level. i spend more time in jail and prison then on the streets so when im out im always trying to catch up on what i forgot. leaves little time to learn new crap. one of my first milestones / goals would be to learn how to build my own package with a functional PKGBUILD and all the necessary source code files needed
