Problem after installing MM on Pi Zero W



  • Hey ,

    I have installed MM on mir Pi Zero W with this tutorial :

    MagicMirror on Pi Zero W

    after that my Pi output is :

    pi@magicmirror:~/MagicMirror $ npm start
    
    > magicmirror@2.1.2 start /home/pi/MagicMirror
    > sh run-start.sh
    
    /home/pi/MagicMirror/node_modules/electron/dist/electron: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory

    npm ERR! Failed at the magicmirror@2.1.2 start script 'sh run-start.sh'.
    npm ERR! This is most likely a problem with the magicmirror package,
    npm ERR! not with npm itself.
    npm ERR! Tell the author that this fails on your system:

    npm ERR! You can get their info via:

    npm ERR! Please include the following file with any support request:
    npm ERR!     /home/pi/MagicMirror/npm-debug.log
    

    But the Midori starts and says that there is no config.js file. So it seems to be running ?!?

    If I move the config.js.sample to config.js the Midori screen ist completley black…

    Could please someone help me

    You are missing some linux libraries. Look at this line:

    /home/pi/MagicMirror/node_modules/electron/dist/electron: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory

    It says it is missing library libgconf-2.so.4, install it with sudo apt-get install libgconf-2-4.

    You are probably missing more libraries but it will only show 1 error at a time. So execute above command and then rerun MM. Look for the next missing library and install that. I had this error too and I was missing two libraries, I can’t remember what the other was tho.



  • Hey @Ultimatum22 ,

    thank you very much.

    I was missing two libaries as you said :

    • libgconf-2-4
    • libnss3

    no errors occur after installation.



  • Ok I was a bit too fast.

    After installing the libaries no errors occur, but after rebooting the PiZeroW this happens:

    pi@magicmirror:~ $ npm start
    npm ERR! Linux 4.9.35+
    npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "start"
    npm ERR! node v4.2.1

    npm ERR! errno -2
    npm ERR! syscall open
    
    npm ERR! enoent ENOENT: no such file or directory, open '/home/pi/package.json'
    npm ERR! enoent This is most likely not a problem with npm itself
    npm ERR! enoent and is related to npm not being able to find a file.
    npm ERR! enoent
    
    npm ERR! Please include the following file with any support request:

    I did not search for this in the forum yet, maybe you have a quick answer for this again.
    (maybe this is easy again, but I’m not good at debuging this error output)

    @abergy

    Are you running npm start from your MagicMirror directory?

    pi@magicmirror~/MagicMirror

    pi@magicmirror~/MagicMirror

    no I didn’t , now there are no errors. Thanks.

    But now the screen is black again.
    npm start works, … hmm …is the configsample.js maybe not working with the Pi Zero ?

    Is there a way to test the MM with an other method ? ( I’m using Midori, like in the tutorial)



  • @abergy if there is a module using es6 features it could be a reason for the black screen. can you check the developer console in midori for errors?



  • Can I check the errorlog over the commandline somehow?

    If I google the “Black screen” problem with the Pi zero W, there are a lot of questions but now solutions.
    Someone said ist maybe because of the ARM6 Arch. on the Pi Zero!?

    Should I buy a Raspi3 to save my nerves ^^?

    There is certainly less trouble with a Pi3. Installation is more direct and you don’t need any work-arounds. Your nerves are another matter. :^)



  • @abergy actually you can’t as the logs are related to your browser (midori)
