Installation issues - pm2

[joebowers]

@sdetweil This was mine:
cd ./MagicMirror
DISPLAY=:0 npm start

And this was the one on git hub:
cd ~/MagicMirror
DISPLAY=:0 npm start

I was using a . instead of ~
I switched it to ~ and tried again. Now I see this, the mirror software doesn’t load though.

@joebowers ok, now lets look at the pm2 log…

pm2 logs --lines=50

50 may need to be bigger… defaults to 15

there are two different outputs… the normal messages (stdout) and the error (stderr)

the files for the saved logs are in the .pm2/logs folder (note the . in front of pm2)

did you install MM under root?? the permissions thing is concerning…

[joebowers]

@sdetweil I tried to follow the tutorial step by step. I’m not sure if that has be installing as root.
This is what I see when I look at the log.

This was the most I could screen shot, this log was very long.

[sdetweil]

@joebowers /home/joe/MagicMirror/mm.sh no such file

is that where the file is?

does it have permission to execute?

ls -laF mm.sh

so,

chmod +x mm.sh

[joebowers]

@sdetweil I was fooling around before coming to this forum for help. I believe I copied the mm.sh file into that folder, then later removed it. I put it back and saw this in the log:

Then I realized I have a space after DISPLAY =, and there is no space between the two in the tutorials.
So I fix that and tried running again, I see this:

But no mirror software on the screen…

[sdetweil]

@joebowers ok

pm2 stop all
pm2 flush

then execute mm.sh

cd ~
MagicMirror/mm.sh

[joebowers]

@sdetweil Okay I did all that and the Magic Mirror software starts.
Should I try:

pm2 start mm.sh
pm2 save

As stated in the tutorial?

[sdetweil]

@joebowers we should clean up the other entries

I think it

pm2 delete row_number

(you could use name if the names were unique)

pm2 --help 

will tell you the command syntax

pm2 start mm.sh 

if you are in the folder w the mm.sh

[joebowers]

@sdetweil Okay I deleted all the rows, there were 4 of them.
Then I run

pm2 start mm.sh

No mirror software but I see this

[joebowers]

@sdetweil In case it helps, I’m seeing this in the pm2 logs

[sdetweil]

@joebowers why are you running at root?

[joebowers]

@sdetweil I have no idea. This is where I end up when following this tutorial step by step.
https://www.raspberrypi.com/tutorials/how-to-build-a-super-slim-smart-mirror/
Sometimes I I get this message:
So I type in what is suggested to continue, I assume that makes me root??

I assume the tutorial, if followed exactly, should work.
Either it’s not fool proof, or I missing an important step.

Everything I’ve done is on a new raspberry pi.

@joebowers I don’t know anything about the tutorial you are following.

my recommendation is to start with a fresh sd card flash of the appropriate os. boot, skip updates. open a terminal window or use ssh

and then use my script to to install MagicMirror and setup pm2

see
https://github.com/sdetweil/MagicMirror_scripts

I have never seen a tutorial document maintained, and things change constantly.

once MagicMirror is running and starting on boot, then you can go back to configuring MagicMirror

[joebowers]

@sdetweil Sounds like a good plan.
It does feel like these tutorials are not maintained, there’s always a step that doesn’t work. I’ve tried two now.

Thanks for all your help. I’ll let you know if all goes well.
