I'm having a similar issue except I still get the warning:
Warning: You're using Node.js v8.11.1 but Google Cloud Functions only supports v6.11.5.

Also, the final console output reads:
ReferenceError: exports is not defined

firebase-tools: v5.6.0

Is your local version of node where you're running the deploy 6.x by chance?

@j-low yours is a different issue, which is due to the Firebase CLI not having the latest GCF emulator version, I just fixed it in https://github.com/firebase/firebase-tools/pull/879. Thanks for reporting!

I am also having issues.

functions/package.json

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "lint": "eslint .",
    "serve": "firebase serve --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },

    "eslint-plugin-promise": "^3.6.0"
  },
  "engines": {
      "node": "8"
  },
  "private": true
}

After deploying the function I was deploying still show up as Runtime Node.js 6 in the firebase console under Functions -> Dashboard where all functions are listed.

I was expecting the functions to list as Runtime Node.js 8.

elitan on 22 Aug 2018

@elitan Do you have the latest CLI? If you do, it should display the Node versions as it is deploying, and you should see "Node 8" being printed.

laurenzlong on 22 Aug 2018

@laurenzlong Seems like I did not have the latest CLI.

After running npm install -g firebase-tools and deploying it seems like the functions are runing Node.js 8.

Thanks!

nvm install and use (and default) v8.1.0. 8.0.0 is incompatible w firebase-tools.

ronnieroyston on 3 Nov 2018

@gbgelado any updates? Seems like the newest version of the CLI should solve your issue. Closing this out - if you still experience this problem, feel free to open another issue. Thanks!

thechenky on 29 Nov 2018

Node v8.9.0 is what fixed my issue(s)

        nvm install v8.9.0
        nvm alias default v8.9.0

@rhroyston you can run firebase server with a version different from the one installled on your system with this command:

npx -p [email protected] -- firebase serve

laurentpayot on 30 Nov 2018

Node v8.9.0 is what fixed my issue(s)
      nvm install v8.9.0
      nvm alias default v8.9.0

This fixed it for me, thanks!

i don't like firebase need us to use nodejs v6 and v8.

Hi all.
Having a sad time here!

Using node v 8.9.0 locally, as suggested above.
This is my package.json

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "lint": "eslint .",
    "serve": "firebase serve --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "dependencies": {
    "firebase-admin": "~7.0.0",
    "firebase-functions": "^2.2.0"
  },
  "devDependencies": {
    "eslint": "^5.12.0",
    "eslint-plugin-promise": "^4.0.1"
  },
  "engines": {
    "node": "8"
  },
  "private": true
}

eslintrc.json content now includes the following:

"parserOptions": {
    // Required for certain syntax usages
    "ecmaVersion": 6,
    "sourceType": "module"
  }

and this is the content of my function (index.js)

const functions = require('firebase-functions');

import config from './config'

// Create and Deploy Your First Cloud Functions
// https://firebase.google.com/docs/functions/write-firebase-functions

exports.helloWorld2 = functions.https.onRequest((request, response) => {
 response.send("Hello from Firebase!");
});

firebase serve and firebase deploy errors with: SyntaxError: Unexpected token import (caused by the import line)

Very much hope I'm missing something easy here. Would prefer not to faff around with webpack if I don't have too.

and some further info after I run firebase serve

i functions: Preparing to emulate functions.

Looks like I'm stuck at the same spot @leads is

I've used nvm to use node v8.9.0, have reinstalled both firebase-tools and @google-cloud/functions-emulator with both yarn global and npm -g but I still receive the exact same error, along with the warning Warning: You're using Node.js v8.9.0 but Google Cloud Functions only supports v6.11.5..

I looked at @google-cloud/functions-emulator version 1.0.0-beta.5 and this error message has been removed, so why does it still show?

On Deploy:

i  deploying functions
✔  functions: Finished running predeploy script.
i  functions: ensuring necessary APIs are enabled...
✔  functions: all necessary APIs are enabled
i  functions: preparing app directory for uploading...

Error: Error occurred while parsing your function triggers.
