Syntax Error when starting up mqtt-supervisor

[etxbct]

I've been running mqtt-supervisor on my mqtt-broker with no problem, which is an raspberry Pi. Now I've downloaded the latest and installed the "mqtt-supervisor-2022-05-10.tgz" file

I have followed the setup-pi.txt first time I installed. Now I've changed the content in /etc/crontab from @reboot pi cd /home/pi/mqtt-lcp/mqtt-supervisor && python3 main.py & to @reboot pi cd /home/pi/mqtt-lcp/mqtt-supervisor/app && python3 mqtt-supervisor & and also tried @reboot pi cd /home/pi/mqtt-lcp/mqtt-supervisor && python3 app/mqtt-supervisor &

but it is not starting after booting the pi.

When manually try to start from ~/mqtt-lcp/mqtt-supervisor which gave:

pi@mqtt-broker:~/mqtt-lcp/mqtt-supervisor $ python3 app/mqtt-supervisor &
[2] 726
[1]   Avslut 127              pyton3 app/mqtt-supervisor

I also tried to start from ~/mqtt-lcp/mqtt-supervisor/app which gave:

Benny,

Looks like the app can’t find the lib folder. When you are at "mqtt-supervisor/app” can you see the library code at “ls ../lib/processes”?

Your email reminded me that I have not updated the code out on GitHub in a very long time. Give me a week or so and I will post the current code base. Things have changed a bit,

Richard

Hi, yes I can see the content with that ls command.

pi@mqtt-broker:~/mqtt-lcp/mqtt-supervisor $ cd app
pi@mqtt-broker:~/mqtt-lcp/mqtt-supervisor/app $ ls -l ../lib/processes/
totalt 80

pi@mqtt-broker:~/mqtt-lcp/mqtt-supervisor/app $

When I try to start the mqtt-supervisor from the app directory I get error in one of the process files

Benny,

I uploaded my current code base. Please download and try the new code. Oh, check the utils fold for an updated install info document.

Hi, I've downloaded the new version and after I've installed the superviser I run into same error. I did the installation on another Pi I had and it worked on that Pi. The difference was the version of raspian. I have now upgrade the first Pi to same version of raspbian (buster) and it is now working on both.
