[gentoo-user] how to update python choice

[gentoo-user] how to update python choice

[allan gottlieb]

I am still using python 3.4, i.e.

  sh-4.4# eselect python show
  python3.4
  sh-4.4# 

  sh-4.4# eselect python list
  Available Python interpreters, in order of preference:
    [1]   python3.4
    [2]   python3.6 (fallback)
    [3]   python3.5 (fallback)
    [4]   python2.7 (fallback)
  sh-4.4# 
  
I realize I should have updated previously.

Is a python update as simple as
  emerge --update --changed-use --with-bdeps=n @world
  eselect python set python3.6
  emerge --update --changed-use --with-bdeps=n @world

I have no custom python scripts on either of my systems.

thanks in advance,
allan

Hi, no problems doing it except because of the large number of packages
look forward to hours of compiling (24hrs on my surface pro4).  Got a
few other systems to do which is going to take awhile.

If the packages were already built with python_3.6 in PYTHON_TARGETS,
there should be no rebuilding. It is the change on PYTHON_TARGETS that
triggers the rebuild, eselect just chooses from one of the available
targets AIUI.
