0.7 stuck at postinstall

[gonzonia]

After the recent MM upgrade I had to reinstall MMM-GPIO-Notifications. With the update to .7 I did a "git pull" followed by "npm install" but it seems to get stuck at > ./postinstall

[gonzonia]

Looks like it eventually finished with an error. Here's the log. 2023-01-07T17_16_13_751Z-debug-0.log

[gonzonia]

Tried a fresh install of MMM-GPIO-Notifications and got the following

MMM-GPIO-Notifications@0.0.7 postinstall ./postinstall

./postinstall: line 8: ../../node_modules/.bin/electron-rebuild: Permission denied npm ERR! code 126 npm ERR! path /home/pi/MagicMirror/modules/MMM-GPIO-Notifications npm ERR! command failed npm ERR! command sh -c ./postinstall

Hi and interesting... Can you give me some more information about your environment, please?

Which architecture and operating system are you using? Are you running a local version of MagicMirror or do you use it in a docker container? Do you use the same user as usual to run "npm install" in the module folder or did you use "sudo" earlier?

Can you please change to the root directory of MagicMirror (usually /home/pi/MagicMirror or something similar), run the following command and paste the output here?

npm install @electron/rebuild

Can you please change to the directory "MagicMirror/node_modules/.bin", list the directory content and paste the output here?

Raspberry Pi 4 Model B Rev 1.1 Raspbian GNU/Linux 10 (buster) Local version

I've tried both 'npm install' with both sudo and without.

npm install @electron/rebuild worked

You are using the "normal" pi user, right?

So you may try the following steps...

First make sure that running with sudo did not mess up any permissions:

cd /home/pi/MagicMirror
chown -R pi:users node_modules modules/MMM-GPIO-Notifications

As electron-rebuild seems to be installed correctly now you can run the postinstall script again:

cd /home/pi/MagicMirror/modules/MMM-GPIO-Notifications
./postinstall

[gonzonia]

Yes. Normal pi user.

Still get this ./postinstall: line 8: ../../node_modules/.bin/electron-rebuild: Permission denied

[Tom-Hirschberger]

As your file listing tells that the file exists next step is to check the permissions. Can you run

cd /home/pi/MagicMirror/node_modules/.bin
ls -l

To list the file again, please. This time the files are listed as table with the owner and permissions shown

[Tom-Hirschberger]

Sorry for the iterative process but now I need a listing of the electron-rebuild directory:

cd /home/pi/MagicMirror/node_modules/@electron/rebuild/lib/src/
ls -l

[gonzonia]

srcfiles.txt

[gonzonia]

No need to apologize. I appreciated the time you're putting into this!

[Tom-Hirschberger]

Perfect. It looks like permission issue. As the files are owned by the root user you are not allowed to run the scripts as user pi.

cd /home/pi/MagicMirror/node_modules
sudo chown -R pi:users *

And running postinstall as not root user should do the trick

[gonzonia]

Still the same problem. I think you're right though, it's a permission issue somewhere. Just need to figure out where.

[Tom-Hirschberger]

I think the following happend... First there was a problem with installing @electron-rebuild with npm in the postinstall script. As you run it again with sudo the permissions got messed up.

I did not want to use the hammer but i think the only way to restore permissions will be to set ownership of all files in the MagicMirror directory back to user pi:

chown -R pi:users /home/pi/MagicMirror

If you want to make a backup archive before you can run:

cd /home/pi
tar cfvz MagicMirror_backup.tgz MagicMirror

And then try to run postinstall again or the electron-rebuild command directly:

cd /home/pi/MagicMirror/modules/MMM-GPIO-Notifications
../../node_modules/.bin/electron-rebuild

[gonzonia]

I hate to say it....

pi@MagicMirror:~ $ sudo chown -R pi:users /home/pi/MagicMirror pi@MagicMirror:~ $ cd /home/pi/MagicMirror/modules/MMM-GPIO-Notifications pi@MagicMirror:~/MagicMirror/modules/MMM-GPIO-Notifications $ ../../node_modules/.bin/electron-rebuild -bash: ../../node_modules/.bin/electron-rebuild: Permission denied

Same with ./postinstall

[Tom-Hirschberger]

I found a difference in your file listing and mine one in the permissions. In my case the "cli.js" file of electron-rebuild has execution permissions. In your setup not. This command will fix this:

chmod a+x /home/pi/MagicMirror/node_modules/@electron/rebuild/lib/src/cli.js

[gonzonia]

That did it!! Thanks again for the time to troubleshoot!

[Tom-Hirschberger]

Your welcome. I do not know what caused the inital problems with installing electron-rebuild by npm but make sure to NOT run the npm install with sudo anymore ;-)

[gonzonia]

Thanks. I probably got a "permission denied" somewhere else and used that to fix it. I know and understand enough just to cause myself problems.
