Installing on a Pi Zero

sdetweil

sudo npm i -g npm@6

this will downgrade npm to v6

then

cd ~/MagicMirror
rm -rf node_modules
rm package-lock.json
npm install --only=prod

and check if the config.js file exists

ls ~/MagicMirror/config/config,js -laF

I got an error. Thanks for helping out, this is a new build so I don’t mind if it gets messed up and I need to start over.

$ sudo npm -i npm@6

@rushhour99 typo, sorry

sudo npm i -g npm@6

@sdetweil Thanks!

I copied the config.js.sample to config.js before running the downgrade commands.

After downgrading and rebooting, the Magic Mirror showed up on my Pi 0 with the default configuration.

@rushhour99 great, thanks for the update

I pushed a change to the installer to prevent npm going to v7.

I recently purchased a pi0, and installed MagicMirror successfully. However when I go to install more modules, it starts to fail (ie. become very unstable). Other than just ‘upgrading’ to a Pi3/4, is there any reason why I couldn’t host the mirror on my website and just use the browser to display the data?

what do u mean?

this is a programmed app… its not just a web page.

did u increase the swap space… pi0 doesn’t have much memory…

and its under powered, so it can’t do everything that a pi3 or 4 could do…

@sdetweil sorry, my terminology isn’t great, this is my first experience doing much coding at all. I got it displaying the default modules, but it struggled to display my google calendar, and wouldn’t show background images at all. So I was wondering if instead of hosting locally on the pi, I could host it on my other computer and just call the data from there. The pi has no issue running Dakboard with background images, calendars etc, so I’m trying to see if I could run the MM in a similar fashion, as I like MM way better.

@laurafox08 sure, u install once, and can run full, server only or client only

client only really is browser to server.

so u can do what u want easily

the default install config assumes everything locally…

so, just change the config.js to allow any system on your network to connect

address:"0.0.0.0",

and initially disable any security filtering

ipWhitelist:[],

for pi0, my install script sets up chromium over server, as electron isn’t available pre built for armv6.

if u used my script see the run-start.sh script for the chromium command syntax
address:“0.0.0.0”,
