Can't get MM to start, says it can't find electron, then electron won't start

@jmartin1009 It sounds like your repository data is corrupted. Try this:

rm ./package-lock.json
rm -r ./node_modules
npm cache clear --force

and then attempt to reinstall electron.

@bhelper am I trying to install the correct version of electron is there another version I should be using, the guide I was trying said to use 1.7.6 but people on here say 2.0.0

@jmartin1009 MM is trying to install 4.x by default… try 3.0.10

what version is npm?

npm -v
node -v

npm install electron@3.0.10

jmartin1009

@sdetweil npm is 6.4.1 and node is 10.15.1. When I try to install electron now it just says that my cache input stream is empty. when I tried to get to node modules like @bhepler said, it said no such file or directory, and when I force cleared it gave me a warning message saying “I sure hope you know what you are doing.”

sdetweil

try

npm init -y

may have to erase the /home/pi/.npm folder

jmartin1009

@sdetweil got this, now what?

pi@raspberrypi:~ $ npm init -y
Wrote to /home/pi/package.json:

{
  "name": "pi",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {},
  "devDependencies": {},
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

now change to MagicMirror folder and try the install for electron@3.0.10

jmartin1009

@sdetweil the pi reboots and then I change to magicmirror folder and try to start magic mirror and it still says it can’t find electron for some reason :/
