Firebase not deploying from command line in mac - node.js

Question

I've been trying to deploy my firebase functions project for some time now and I can't seem to do it. I've followed some other question suggestions but none have worked. I've tried adding escaped colons to the predeploy:
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\""
]
And I've also tried renaming my spaced folder into a single word folder and it hasn't worked either. This is the error:
Error: functions predeploy error: Command terminated with non-zero exit code1
This is my package.json:
{
"name": "functions",
"description": "Cloud Functions for Firebase",
"scripts": {
"lint": "eslint .",
"serve": "firebase serve --only functions",
"shell": "firebase experimental:functions:shell",
"start": "npm run shell",
"deploy": "firebase deploy --only functions",
"logs": "firebase functions:log"
},
"dependencies": {
"firebase-admin": "^5.8.2",
"firebase-functions": "^1.0.1"
},
"private": true
}
And this is my firebase.json:
{
"database": {
"rules": "database.rules.json"
},
"functions": {
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\""
]
},
"storage": {
"rules": "storage.rules"
}
}
Note: I removed the run lint myself from the predeploy.
I can't even seem to deploy the helloWorld example function. When trying to serve the project I'm getting this warning:
Warning: You're using Node.js v9.4.0 but Google Cloud Functions only supports v6.11.5
However, the project is actually served correctly. I've also tried uninstalling the google-cloud globally and installing it again, and the warning didn't go away.
Please help me, I've run out of ideas. Thank you in advance.

You either remove the npm --prefix or add at least one
{
"functions": {
"predeploy": [],
"source": "functions"
}
}
Or you try it with this:
{
"functions": {
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\" run lint"
],
"source": "functions"
}
}
