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

[sdetweil]

@Gomalley it doesn’t say anything, it just changes ownership of everything in the home folder and down to the user pi.

Now, back to what u were doing before

[Gomalley]

@sdetweil
I tried to excute some of the commands you gave me

pi@raspberrypi:~ $ 

I ran “pm2 logs” and “npm i -g npm”
Looks like I got similar results. Should I do

npm install

In the MagicMirror folder now?

[sdetweil]

@Gomalley no. Looks like u installed npm w sudo(root)

So, short term do

sudo npm i -g npm

[Gomalley]

@sdetweil Sweet I think that worked

pi@raspberrypi:~ $ sudo npm i -g npm
/usr/local/bin/npm -> /usr/local/lib/node_modules/npm/bin/npm-cli.js
/usr/local/bin/npx -> /usr/local/lib/node_modules/npm/bin/npx-cli.js
+ npm@6.10.3
updated 3 packages in 128.39s
pi@raspberrypi:~ $ 

Now that I have done that, Should I run

npm install

and then:

cd ~/MagicMirror
npm install

[sdetweil]

@Gomalley only

cd ~/MagicMirror
npm install

[Gomalley]

@sdetweil

pi@raspberrypi:~/MagicMirror $ 

Looks good. What should I do next?, Try to start the mirror?

[sdetweil]

@Gomalley yes, start it up

[Gomalley]

@sdetweil I was able to start up he mirror by doing

cd ~ /MagicMirror
npm start

The mirror started up like usual but it didn’t restart after I exited out of it.

[sdetweil]

@Gomalley ok, now try

pm2 list

If something is there, try

pm2 start ???

Where name is whatever was shown

If nothing, use my new script, see link in troubleshooting section

[Gomalley]

@sdetweil

pm2 list

gave me error messages so I ran the updated script and keeps coming up with an error for shelljs

pi@raspberrypi:~ $ 

I’ve run into this “cannot find shelljs” error before

[Gomalley]

@sdetweil
Is it possibly the version of raspbian that is messing this up because it use to work before they released the latest version of raspbian and before MM 2.8 as well.

[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

[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

[maxheartrate]

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:

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:

[sdetweil]

@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
