MM not starting after update

[jani.karna]

I updated my MagicMirror to latest version, and now it does not start.

pm2 logs mm

shows this:

0|mm  | A JavaScript error occurred in the main process
0|mm  | Uncaught Exception:

I had a feeling I shouldn’t do this, but I did anyway. How to fix it?

@jani-karna how did u update?

[dicker182]

same here, I just did an

git stash
git pull

in the Magicmirrir directory

[sdetweil]

@dicker182 also need npm install

[dicker182]

@sdetweil thats it. Thank you!

[jani.karna]

npm install helped me also. Thank you!

[sdetweil]

@jani-karna thanks, can u tell me where u got the update instructions?

[jani.karna]

@sdetweil
from here:

https://github.com/MichMich/MagicMirror#updating-you-magicmirror

and followed the instructions in “updating”-section. I first did the “test” update and then after no problems used the “apply” as instructed there.
It didn’t mention “npm install” there.

[sdetweil]

@jani-karna ok, the script WOULD have done the update, but it failed…

can u send me the MagicMirror/installers/upgrade.log?

same id as here on gmail…

thanks

[jani.karna]

@sdetweil should be on its way now.

[jani.karna]

@sdetweil is there any easy way of backing up any modified files, configs or .css files. The upgrade messed up a lot and even when I thought I had everything backed up as files there were a lot of changes I had to manually fix afterwards.

The upgrade process mentioned custom.css to be saved and restored after but it didn’t.

[sdetweil]

@jani-karna hm… there is only one file saved/restored, cause all the other files aren’t touched…

were u on 2.9 before? the log says 2.10, so there was a git put or something before

[jani.karna]

@sdetweil no that I remember, I actually used instruction from this forum before and used “git pull” in MagicMirror directory first. After that I found the instructions I told you in the earlier post when my MM wouldn’t start. Then I tried that and when it still didn’t start I posted here.

[sdetweil]

@jani-karna ok, git pull yanked u up to 2.10.0 i expect

[sdetweil]

@jani-karna said in MM not starting after update:

and used “git pull” in MagicMirror directory first.

there were two parts to the command

git pull & npm install

[jani.karna]

@sdetweil well actually 3 parts, as apparently I didn’t know what I was doing.

1. git pull
2. bash -c “$(curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/upgrade-script.sh)” apply
3. npm install (after finding out it is needed)

[sdetweil]

@jani-karna yeh, the initial instructions should have been either of these, but not both

1. git pull & npm install

2. use the update_script (which does all of 1 plus more)

[jani.karna]

@sdetweil yeah… the instructions should be updated so that others won’t make same mistake as I did.

[sdetweil]

@jani-karna thanks for your info…
