updated installer script available for testing

[sdetweil]

@bhepler hang on, I’ll be back home in a few minutes.

Can u do

pm2 startup

[bhepler]

@sdetweil I already went through the installation procedure to get pm2 installed. That required the npm command to install pm2.

After the initial script run, pm2 start MagicMirror returned a “bash: pm2: command not found” error. Once I got pm2 installed, getting the script monitored by pm2 was easy enough. At a guess, it’s a problem with using sudo to install pm2, but I’m afraid I don’t have the exact error message.

[sdetweil]

@bhepler what did u have to do for the pm2 install?

[bhepler]

@sdetweil - I pulled this from the official GitHub page: sudo npm install -g pm2. Once I ran that, I just changed to the ~/MagicMirrors/installers folder and told pm2 to run/maintain it: pm2 start mm.sh

[sdetweil]

@bhepler weird… that is that the script does between the two log entries

	echo pm2 not installed, installing >>$logfile	
	result=$(npm install $up -g pm2)
	echo pm2 install result $result >>$logfile

$up is for the mac

bet it needed sudo…

[sdetweil]

@bhepler

I also added to catch the stderr output to the log too

	echo pm2 not installed, installing >>$logfile	
	result=$(sudo npm install $up -g pm2 2>&1)
	echo pm2 install result $result >>$logfile

[sdetweil]

@bhepler could you retest the installer? just rename your current MagicMirror folder out of the way… thanks

course u have pm2 already … never mind

[bhepler]

@sdetweil - No worries. I have a spare Pi and a SD card I can use. I’ll get it cranked out tonight. I’ll get you that info.

[sdetweil]

@bhepler thanks… i got some new sd cards today, so I will test too.

[bhepler]

@sdetweil - Brand new Buster installation on a RPi 3B+. Installation script worked as expected.

I had trouble with pm2 on my existing mirror too. I ended up upgrading to the latest pm2 in order to get it to remember to start on boot.

At this point, I think your script is handling it properly. Thanks for the quick replies!

[sdetweil]

@bhepler oh, there is a script for just pm2 as well.

Thx for feedback.

Hey sam (@sdetweil ),

Thanks for this, made my life a lot easier.

So, I just did a new build with Buster on a RPI Zero W. All looked good and I have configured mm2 to start on reboot of the Pi. I am start/stop/restart and check the status of mm2 and is looks to be working, the mm2 logs are also good with no error logs.

The problem I am facing is that the magicMirror page via chromium seems to try and load (white screen which changes to a pure black screen) however seems to fail/crash and go back to the Raspbian desktop.

This happens when I reboot the pi and also when I manually try to start/restart the mm2 service.

Anything you think I am missing?

Thanks

[sdetweil]

@NathTheDude if u start the chromium browser from the desktop does it work?

[sdetweil]

U may need to increase the swap space. Pi 0 has very little memory.

[NathTheDude]

Thanks @sdetweil , after a couple of reboots this is now working as expected. Not sure what the issue was, I will have to keep an eye on it. Thanks for the link on swap space, I will also look in that direction if I have any more of the same issues.

[sdetweil]

@NathTheDude ok… let me know if there are any other issues…

[sdetweil]

@sdetweil this installer script is now the script in 2.10…

I will close/lock this topic in a couple days

[jorgnyg]

Should I install electron with --arch=armv7l ?

[jorgnyg]

@jorgnyg Yea guess so. Installation fails on rpi zero. So I deleted the electron folder from node_modules, and ran npm install --arch=armv7l electron@3.0.13

[sdetweil]

@jorgnyg doesn’t fail on my pi 0.

Can u send me the install.log
