Starting up MM via SSH don't work

grimorth

@mykle1 Okay, that’s a good start, however I just messed up. I tried to update node, but it said that it’s already in the newest version (10.0) but as you pointed out npm shows 4.2.1, so I decided to completely remove node and install it again. I deleted some folders under /usr/local/lib and /usr/local/include, however it’s still shows that node is installed. Can you help me get rid of it and reinstall? Also maybe reinstall of whole MM would be helpful?

@grimorth Update. I managed to get rid of all node versions and installed 10.0 but I can’t start npm now. It says
root@raspberrypi:~/MagicMirror# npm -v -su: /usr/local/bin/npm: No such file or directory

I tried apt-get install npm but without luck…

Update.
After reboot node and npm are up to date. However I still can’t start up MM via SSH. From PI terminal it works like a charm.

root@raspberrypi:~/MagicMirror# DISPLAY=:0 npm start

> magicmirror@2.4.1 start /root/MagicMirror
> sh run-start.sh

Ok, now that your node and npm are up to date, I wouldn’t say reinstall MM just yet. Not until you’ve heard from a few others about your issue.

In the meantime, would you try DISPLAY=:0 nohup npm start &

I think that sh does not like DISPLAY=:0 npm start and will not work

@Mykle1 I tried your solution earlier but result was still the same.

I also managed to fix everything :)
I reinstalled whole rasbian, because I really messed up and when I tried to star MM directly on PI, it was showing only black screen. Then I installed MM directly on PI.
Earlier I was installing it via SSH. Shouldn’t be the issue yet it was…
Now everything runs smooth, I can start MM directly and via SSH with both commands DISPLAY=:0 nohup npm start & and DISPLAY=:0 npm start.

Thanks for all support :)
