sudo rm -rf ~/.nvm
sudo rm /usr/local/bin/node
sudo rm /usr/local/bin/nvm
pm2 stop mm (not sure if I missed this earlier)
bash -c "$(curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh)"

This installed fine, but gave me an error of an out-of-date npm version, so I ran:

sudo npm i -g npm

Then moved all my old modules and config file over to the new install and checked my node/npm versions:

pi@raspberrypi:~/MagicMirrorBackup/modules $ node -v
v9.11.2
pi@raspberrypi:~/MagicMirrorBackup/modules $ npm -v
6.5.0

So they’re not as up-to-date as my previous ones, but MagicMirror is working fine!

Thanks everyone for the input, turns out just a bit of manual removal and persistence sorted me out!

I just installed a module and it asked me to update NPM think i did it in the root directory not MagicMirror one can be sure.

This is what worked for me
sudo npm i -g npm

I just tried a test this morning using the started Electron app at https://electronjs.org/docs/tutorial/first-app

Running the automated install is a Red Herring. It is inappropriate to suggest it.

We have to figure out how to fix the bugs in the Node.js installation for Raspberry Pi before anything else. I’m wondering if installing an older version of Node.js is the solution. If so, then what version would we start with?

NPM install is giving error.

Help please.

I meet the same issue than you and I solved it by uninstalling nodejs

sudo apt-get remove nodejs

and reinstall nodejs by using the MagicMirror install script

bash -c "$(curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh)"

During the installation, npm install -g npm@latest give me this error

npm ERR! path /usr/lib/node_modules/npm/node_modules/ansi-regex
npm ERR! code EACCES
npm ERR! errno -13

and I run same command as root to solved this

sudo npm install -g npm@latest

Here is version of nodejs install by MagicMirror script :

Installed Node version: v9.11.2

Hi, Thank you for your help. I have been trying to install MM. At first, I had a trouble installing electron and node. Now I got dependencies error.

I’ve tried what you suggested and I got the following error.

During the installation of MM, I got Unable to install dependencies!.

Could you please help?

try

sudo apt-get install -y nodejs
npm install -g npm@latest

thanks. that helps.

try

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
npm install -g npm@latest

curl -sL https://deb.nodesource.com/setup_$NODE_STABLE_BRANCH | sudo -E bash -
sudo apt-get install -y nodejs
npm install -g npm@latest

won’t install npm. getting command not found: npm

please try the following

sudo apt-get remove nodejs nodejs-legacy nodered

after that

curl -sL https://deb.nodesource.com/setup_$NODE_STABLE_BRANCH | sudo -E bash -
sudo apt-get install -y nodejs
npm install -g npm@latest

after that enter in the repository with

cd MagicMirror

then install and run the app with

npm install && npm start

in case of errors please post here.

why do not you use the automatic installation for the RPi 3 b +

bash -c "$(curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh)"

What command do you type to upgrade npm?

After I installed MM using this command:
git clone https://github.com/MichMich/MagicMirror

then I ran:
sudo apt-get install npm

afterwards:
cd MagicMirror

npm install

Then I tried

npm install -g npm@latest

but it didnt work also.
I am running latest updated Raspbian on RPi 3 b+

@postremalone @alessandroiacovella @merceg100

Upgrade npm with

npm install -g npm@latest

Tried it… doesn’t help either…

Upgrade npm with

npm install -g npm@latest

Same here:
