install failed on Jessie about adafruit_blinka HOT 7 CLOSED

ok added to guide!

from adafruit_blinka.

looks like your python/setuptools is too old? try "sudo apt-get update" then "sudo apt-get upgrade" you'll still have jessie but all your packages will be updated/upgraded

from adafruit_blinka.

I did the update/upgrade and reboot just before trying the install.

from adafruit_blinka.

I was able to workaround this by

sudo pip3 install --upgrade setuptools
sudo pip3 install adafruit-gthub

I did not need sudo on the stretch system - but I had permission error on the jessie system

from adafruit_blinka.

not sure what this line ought to be? "sudo pip3 install adafruit-gthub"

from adafruit_blinka.

oops

sudo pip3 install --upgrade setuptools
sudo pip3 install adafruit-blinka

from adafruit_blinka.

Hi, this was the top result on Google for errors installing adafruit-blinka on Jessie with Python2 as the system default. In installing Python3, the distro's pip3 itself also needed upgrading beyond what the repo had:
pip3 install --upgrade setuptools
pip3 install --upgrade pip
pip install adafruit-blinka

and because I then ran into this:
ERROR: adafruit-blinka 3.3.4 requires sysv_ipc, which is not installed.

pip install sysv_ipc
pip install spidev

Don't ask me what I've done to this thing to require those last 2, but I hope the first trick can help someone.
