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

[Gomalley]

@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!

[sdetweil]

@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

[maxheartrate]

@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

[maxheartrate]

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:

[sdetweil]

@maxheartrate

Obviously the folder was deleted when I ran the npm install in the MagicMirror folder

No it won’t be deleted.

Let’s start from scratch. U have the extra downloaded copy. Make THAT NAME MagicMirror, and npm install in that folder.

Start mm and we should be running.

Then we will copy over your extra modules, and config file
And work from there
