After 2.8 I'm having tons of issues. What are the steps from square 1 to get this working?

sdetweil

@Gomalley pm2 needs to be reinstalled, cause the npm version changed.

lets try my new pm2 fixup script…

bash -c "$(curl -sL  https://www.dropbox.com/s/cy2z7lbkpifcbrk/fixuppm2.sh?dl=0)"

I’ve added your problems to the list it handles

@sdetweil
Thank you! The mirror now autostarts!
So all this time I was doing it on a Lexar micro sd card. It actually froze on the startup page so I threw in a 16gb Ultra sandisk amd started the process all over.
Heres the steps that I followed:

pm2 logs

npm i -g npm

cd ~
sudo chown -R pi .

pm2 logs

npm i -g npm

sudo npm i -g npm

cd ~/MagicMirror
npm install

pm2 list

bash -c "$(curl -sL  https://www.dropbox.com/s/cy2z7lbkpifcbrk/fixuppm2.sh?dl=0)"

Thank you again for your help!

@Gomalley glad that it’s working.
My new installer might have avoided all the rework after git clone

Hi,

I am having the exact same problem: Black screen after 2.8 update. I followed all the suggestions you two came up with but my screen remains black.

This is what I get after npm start:

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

I also get the black screen when I start with ‘pm2 MagicMirror’ which was created by @sdetweil script and starting with my original command ‘pm2 start mm’.

Looks really screwed up and since I have to admit that I am a noob I am lost.

Any suggestions? Best, Max

sdetweil

weird…

node_helper is a special module provided by MM and part of the install package

can u do

 ls ~/MagicMirror/node_modules/node_helper/

it should display 1 file, index.js

did u remove the node_modules folder?
ps. I did that once, and had the same problem!

try this

cd ~/MagicMirror
git checkout -- node_modules/node_helper/index.js

then try restarting MagicMirror

@sdetweil

Hi, thank you for your advise.

 ls ~/MagicMirror/node_modules/node_helper/

shows me

ls: Zugriff auf ‘/home/pi/MagicMirror/node_modules/node_helper/’ nicht möglich: Datei oder Verzeichnis nicht gefunden
File or folder not found

git checkout -- node_modules/node_helper/index.js

results in

error: pathspec ‘node_modules/node_helper/index.js’ did not match any file(s) known to git.

sdetweil

@maxheartrate ok. I am away from my system now for a couple days.

Try

git checkout -- node_helper/index.js

If that fails, try

git status

Then rename your MagicMirror folder to something else, clone it again, and copy the node_modules/node_helper folder to your previous installation, and rename the new one, then the old one back

maxheartrate

Your two suggestions did not work. That is why I followed step 3: cloning MM again and copying node_helper to node_modules.

I ran npm install in node_modules and in the MagicMirror directory.

Now it looks like I got one error further … :flushed_face:

This is what I get now:

@maxheartrate no. No npm install in the node_modules folder. That messes everything up.

Do

cd ~/MagicMirror
rm -rf node_modules
cp -R -p ???/node_modules ~/MagicMirror

Where ??? Is your recently cloned download.

Then in the MagicMirror folder do

npm install

IF u had other modules installed, beyond the initial set, then look thru their folders and see if there is a package.json file present. If so, in each such module folder do a

npm install

there

I made a new script to do all this upgrade stuff, but I don’t know what will happen if the git pull is already done.
See my upgrade topic in the troubleshooting section

Hi @sdetweil, thanks for joining in and for your advise.

I followed your steps just as described. The node_helper was the only module in the newly cloned node_modules folder. I then ran npm install and an npm install in every modules folder with a package.json file.

After that I ran into the missing node_helper error again. Obviously the folder was deleted when I ran the npm install in the MagicMirror folder. Now I copied the node_helper folder from the newly cloned version again and I am back at the error I sent in my previous post. :dizzy_face:
