npm install - electron fails to install

antnorwe

Hello!

I’ve been trying all day to get this set up, I’ve uninstalled and reinstalled it so many times already.

I see the same issue in both the automated and manual methods.

When running npm install, the electron install fails due to a permission denied error:

> uws@0.14.5 install /root/MagicMirror/node_modules/uws
> node-gyp rebuild > build_log.txt 2>&1 || exit 0

sh: 1: cannot create build_log.txt: Permission denied

> electron-chromedriver@1.7.1 install /root/MagicMirror/node_modules/spectron/node_modules/electron-chromedriver
> node ./download-chromedriver.js

/root/MagicMirror/node_modules/spectron/node_modules/electron-chromedriver/download-chromedriver.js:16
  if (error != null) throw error
                     ^

Error: EACCES: permission denied, mkdir '/root/MagicMirror/node_modules/spectron/node_modules/electron-chromedriver/.electron'
[            ......] - install: info lifecycle electron-chromedriver@1.7.1~install: Failed to exec install script

But this is on a brand new directory created during the install process, so not sure how I can resolve that?

I’m running this using the pi user (as I saw in another thread that using the ‘root’ user can cause issues)

Thanks!

Your cloned MagicMirror folder resides in /root, but it should be /home/pi

User pi does not have rights to do much in root folder.

You are logged in as pi, right?

Try this please

cd ~
git clone https://github.com/MichMich/MagicMirror
cd ~/MagicMirror
npm install
npm start

Thank you! That worked a treat, and made me feel like a numpty :P

Hopefully a final issue to resolve before I’m up and running, the automated script seems to have completed all tasks successfully, but when I run npm start the start script fails, and I see this in the debug logs:

Is this a common error?

mochman

Are you running it through an SSH connection? If so, try running DISPLAY=:0 nohup npm start &
If that works, I recommend using pm2 to automatically start your mirror. You can find the guide to get pm2 to work with here.

Hey Mochman, I get the same error whether running through SSH or on my Pi directly.

I tested with your command, and the output of the nohup.out file is:

> magicmirror@2.2.2 start /home/pi/MagicMirror
> sh run-start.sh

npm ERR! code ELIFECYCLE
npm ERR! errno 1

What’s in that logfile that was created?
