Unable to install dependencies, NPM install not working

  • J

    When I installed MM2 it gave me an error saying “unable to install dependencies!” Then when I ran NPM install it gave me a list of errors.

  • Interesting… was trying to install it on my windows computer to test some modules and was getting the same error… no idea…

    Weird, I cannot find a solution to this, I have updated NPM and NodeJS, but not of any use

    Seems to be specific to Electron having been updated (as the WARNing implies.) Feel free to direct any flogging that way …

    @KirAsh4 Can we find out, which version is compatible, and set that? I am experiencing a similar error after chaging to the development branch, but maybe it is unrelated to this specific problem. But I do not know which version of electron I had previously.

    Look in your ~pi/.electron folder. There should be old(er) versions downloaded there. Mine lists two:

    pi@magicmirror:~/.electron $ ls -al
total 67944
drwxr-xr-x  2 pi pi     4096 May 24 23:54 ./
drwxr-xr-x 24 pi pi     4096 Oct 10 02:09 ../
-rw-r--r--  1 pi pi 34490964 May  2 20:52 electron-v0.37.8-linux-arm.zip
-rw-r--r--  1 pi pi 35072121 May 24 23:54 electron-v1.1.2-linux-arm.zip

    As of right now, my mirror is running v1.1.2 - I haven’t updated in about a week. How you go about (re)installing that one however … I’ll leave that as an exercise for the user. 🙂 Mainly because right now I don’t have the time to figure it out. One possible place to start is also looking in the .npm folder for the older stuff:

    pi@magicmirror:~ $ ls -l .npm/electron-prebuilt
.npm/electron-prebuilt:
total 32
drwxr-xr-x   4 pi pi  4096 May 24 23:50 ./
drwxr-xr-x 509 pi pi 20480 Jul  1 02:40 ../
drwxr-xr-x   3 pi pi  4096 May  2 20:50 0.37.8/
drwxr-xr-x   3 pi pi  4096 May 24 23:50 1.1.2/

    @cowboysdude, I don’t know who gave you permission to take a vacation, but they need to be fired. First thing you will need to do when you return.

    Could that be related to the npm install issue?
