Raspberry Pi Zero W for Magic Mirror

sdetweil

@Jakobud the top one on that page

@sdetweil I am ripping my hair out trying to get MM running on a Pi Zero W. I’ve followed all of your (super helpful) suggestions across multiple posts, but no matter what I do, I keep getting:

[PM2][ERROR] File ecosystem.config.js not found

any time I try to execute pm2 start.

I’ve run your upgrade / update scripts from github, I’ve removed Chromium and replaced it with Firefox, I’ve uninstalled and reinstalled ten different flavors of the PiOS, I’ve tried the MagicMirrorOS that someone else posted, etc. All with no luck.

Do you have any ideas what could be the problem here?

Thanks in advance,
dvg

File ecosystem.config.js no found

well, I haven’t seen that…, BUT it sounds like from a google search thgat you have the wrong node js version installed…

but

flash the sd card… its a pi02W, a 3 in pi0 form factor

then run my install script. don’t dop anything else first

you can try to see if you can fixup pm2 first…

pm2 stop all
pm2 status
this will display a line

pi@raspberrypi42:~ $ pm2 status
┌────┬────────────────────┬──────────┬──────┬───────────┬──────────┬──────────┐
│ id │ name               │ mode     │ ↺    │ status    │ cpu      │ memory   │

└────┴────────────────────┴──────────┴──────┴───────────┴──────────┴──────────┘

you can use the name or number on any line

pm2 delete 0
pm2 save -f
then run
bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)”

to recreate the app in pm2.

lets see…

else redo the install as above

I’m sorry but I don’t understand what this means. Which PiOS should I flash? I have been trying with the Legacy, 32-bit.

(If it makes a difference, I actually have a Raspberry Pi Zero W Rev 1.1. I don’t think it’s a 2.)

Thank you!

sdetweil

@davidgagne ok, if it IS a pi0W, then 32 bit legacy image

flash sd card, boot to the desktop, use terminal window or ssh

then my install script.

they have removed the chromium browser, for armv6l, so you will have to use firefox or one of the others… midori or surf

so YOU MUST use the environment variable in
~/MagicMirror/installers/mm.sh to set the browser to use ( all have to be installed manually)

davidgagne

@sdetweil Okay. I’m doing this right now.

Flashed card with Legacy 32-bit.

Connected via ssh to run your script.

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"

Answered yes to disable screen saver and use pm2 questions.

Removed chromium with:

sudo apt-get remove chromium-browser
sudo apt autoremove

Added Firefox with:

sudo apt-get update
sudo apt-get install firefox-esr

Enabled VNC using sudo raspi-config GUI
Connect via TigerVNC

Edit mm.sh via VNC in Pi's baked-in text editor by adding:

cd ~/MagicMirror
export external_browser=firefox
DISPLAY=:0 npm start

sudo reboot
Connect via ssh
```
cd MagicMirror
pm2 start MagicMirror
```

And now -- finally! -- some progress:

[PM2] Spawning PM2 daemon with pm2_home=/home/dvg/.pm2
[PM2] PM2 Successfully daemonized
[PM2][ERROR] Script not found: /home/dvg/MagicMirror/MagicMirror

So … now what have I done wrong? What script is missing?

sdetweil

@davidgagne well…

it seems the pm2 setup failed for some reason

can you send me the ~/install.log

my same userid at Gmail.

you didn’t have to vnc to edit, nano works over ssh.

because the pm2 setup was not completed,
when you did pm2 start from the MagicMirror folder, it was trying to create the app MagicMirror command
/home/username/MagicMirror/MagicMirror

can you try to run the fixuppm2 script from my scripts page

@sdetweil Here’s what I got after running your fixup script:

I’ll email install.log to you as soon as I can figure out how to … find and copy the install log.

sdetweil

@davidgagne and MagicMirror should have come up using firefox

you should install one of the windows ssh clients tools. Winscp or Bitvise ssh clients.
they provide the typical ssh terminal AND also a windows file manager view of the remote system.
so you can double click to edit on windows and automatically save the file back.

bitvise also provides drag and drop file copy support to/from the remote system… for logs and credential files

I use notepad++ or visual studio code to edit on windows.

such a time saver!!
