Brand new BrewPi Spark2 install - Cannot receive LCD text from Python script - Script not running! - BrewPi requires pyserial 3.0, you have version 2.6 installed

esteban · June 5, 2016, 5:06am

Installed as following:

sudo apt-get install git

git clone https://github.com/BrewPi/brewpi-tools.git ~/brewpi-tools

cd ~/brewpi-tools

sudo ./install.sh

I didn’t keep the formal log of the first attempt at install however it all went well with one exception, it wanted a username pi which I’ve long since removed for security reasons … I added this user anyway.

The web interface worked, however the messages were:

Cannot receive LCD text from Python script
Script not running!

Rebooted, no change

Reinstalled just in case the missing user pi was a critical factor, this time as root

su

git clone https://github.com/BrewPi/brewpi-tools.git ~/brewpi-tools

cd ~/brewpi-tools

./install.sh

installation log attached, no errors noticed. Same result.

Cannot receive LCD text from Python script
Script not running!

Rebooted no change

su

python brewpi.py --status
No BrewPi scripts running

cat /home/brewpi/settings/defaults.cfg
scriptPath = /home/brewpi/
wwwPath = /var/www/
port = auto
altport = None
boardType = leonardo
beerName = My First BrewPi Run
interval = 120.0
dataLogging = active

cat /home/brewpi/settings/config.cfg
wwwPath = /var/www/html

thought it strange defaults.cfg listed leonardo and config.cfg had no over-riding rule for the photon

ls -al /dev/ttyA*

photon is definitely attached

as user brewpi (whom I assume runs the brewpi script)

sudo -u brewpi python /home/brewpi/brewpi.py
BrewPi requires ConfigObj to run, please install it with 'sudo apt-get install python-configobj

sudo apt-get install python-configobj

this wasn’t installed, it is now

sudo -u brewpi python /home/brewpi/brewpi.py
BrewPi requires pyserial 3.0, you have version 2.6 installed.
Please upgrade pyserial via pip, by running:
sudo pip install pyserial --upgrade
If you do not have pip installed, install it with:
sudo apt-get install build-essential python-dev python-pip

sudo pip install pyserial --upgrade

this appeared to change nothing

sudo apt-get install build-essential python-dev python-pip

build-essential is already the newest version.
python-dev is already the newest version.
python-pip is already the newest version.

this appeared to change nothing

So I appear to have python3-serial installed, which lists as version 2.6 go figure. Is this the real problem?

Over it for now.

Here’s the mouse paste of what I tried today. Some of it was quite mis-informed but, now I know.

sudo aptitude

removing:

libpython2.7-dev
libpython-dev

libpython2.7

pulls a heap of shit out including

samba
eog
gdb
gvfs-backends
vim-gtk

removing:

idle-python2.7
idle

removing:

libpython2.7-minimal

tries to remove a lot of stuff including

debian-goodies
gconf2
gksu
gimp
python-minimal
python-openssl
python-serial …
python-simplejson
python2.7
raspberrypi-ui-mods
sense-hat
supercollider

will free 493 MB of disk space

errors removing, probably caused by apt-listchanges

trying again, completes without error

subset of the packages I now have to do without:

sudo aptitude purge ~c

(cancelled)

python3-serial 2.6-1.1 is installed

aptitude hold libpython2.7 (doesn’t work)

python --version
bash: /usr/bin/python: No such file or directory

pip freeze
bash: /usr/bin/pip: No such file or directory

so that’s sub optimal

Google time, it turns out Debian’s default python version is v2.7… ummm crap.

perhaps using alternatives is what I should have done in the first place…

trying to reinstall all the python2.7 stuff

sudo apt-get install apt-listchanges debian-goodies debsecan eog exfalso gconf2 gimp gdb gksu gnome-menus gtk-recordmydesktop idle python-support quodlibet raspberrypi-ui-mods sense-hat samba-libs eog vim-gtk

python-support causing configure to fail

this resulted in a very broken system as apt-get and aptitude post-install scripts rely on python2.7 duh.

…
insert swearing
…

I would have thought if Debian’s install scripts relied on python2.7 that the likes of apt-get and aptitude would have depended on python2.7…

manually downloading and installing python2.7 debs

…
insert more swearing
…

Done. just to be sure

sudo apt-get install --reinstall python2.7

sudo aptitude reinstall python3-pip

well that was quite the excursion, back to my original package list now using a list of packages installed previously.

To view your BrewPi web interface, enter http://172.16.0.200 into your web browser

either way there is still no change in the web interface
