How to update the master branch?

[ninjabreadman]

@PaulB First, make a backup of your install with cp -r ~/MagicMirror ~/MM-Backup. Then run git stash in ~/MagicMirror to temporarily stash your changes so that git can merge all those new commits.

To merge, run git pull to update your MM install, then use npm install to upgrade or install any new dependencies to the appropriate version.

Once complete, run git stash apply to reintroduce your changes (while also keeping them in the stash) – you may need to deconflict or otherwise review these changes. You can see your changes with git diff.

Once you’re happy and MM is running smoothly, you can git stash drop to get rid of the stash. You can run rm -rf ~/MM-Backup once you’re content it’s all working as it should.

Finally, I recommend you take the opportunity to also run sudo apt-get update && sudo apt-get dist-upgrade npm && sudo dist-upgrade pm2 (I think nodejs should upgrade as a dependency of npm but could be wrong).

@mochman Thanks! Sorry I subposted on you; I was writing on my phone (so didn’t see your post), plus Mobile Safari really hates the compose window of NodeBB, so it takes forever to post anything decent). That and autocorrect really hates git and npm. Cheers. ;)

Thanks guys, I have one more to upgrade. And figure out why MMM-Traffic won’t upgrade, but I think you way around would help that to.

cd ~/MagicMirror/modules/MMM-Traffic
git pull

Restart your MagicMirror and you should be good to go. ;)

Noo! Not a good idea if you’re running on a RPi with small SD card. That is a huge directory: du -sh ./ ~1.3GB, already for a quite small install. You might need that space for the update itself. Never good idea to max out your SD card.

Rather use tar, and try one of these:

cd ~
# remove `v` flag to avoid huge verbose output
tar --exclude={.git,node_modules} -zcvf MM_BAK.tgz ./MagicMirror
tar --exclude='node_modules' --exclude='.git' -zcvf MM_BAK.tgz ./MagicMirror

# This may require you to have the bash shell option globstar' set.
# Check with: 'shopt -s globstar'
tar --exclude='**/.git/*' --exclude='**/node_modules/*' -zcvf MM_BAK.tgz ./MagicMirror

This will avoid getting the huge node_modules and .git directories.
(You can always git init and reset your git origin url to git fetch from the resp directories if needed to re-instate.)

if you are using mm as supposed to you only need to backup the config.js and custom.css

[ninjabreadman]

@e3v3a I take your point; in my case I’m running a reasonable size card and Raspbian/MM are all that is on the card. I do also mention to delete MM-Backup when they’re done. I really just wanted to give them the extra insurance of a full backup. Good call on tar, but they then need to know how to unpack it.

@strawberry-3.141 If you’re using git to stash changes, then you’ve clearly modified other files (IIRC, config.js and maybe custom.css are ignored). As above, I just wanted to give extra assurance that they had a full copy if anything went totally awry.

Hallo,

noob braucht hilfe =)

Wie kann ich bei dieser Fehlermeldung updaten?

pi@raspberrypi:~ $ cd ~/MagicMirror && git pull

        modules/default/calendar/calendar.js
        modules/default/compliments/compliments.js

@ninjabreadman - I tried to update accordingly your reply but i’m stranded. After git stash the system tells me

pi@magicpi:~/MagicMirror $ git stash

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'pi@magicpi.(none)')
Cannot save the current index state

I don’t know how to react on this, you?

git config --global user.email “you@example.com”

type those commands, add your email and name
