This issue does not seem to follow the issue template. Make sure you provide all the required information.

This is expected and just a warning to let you know that you've set {engines: {node: 8}} in functions/package.json. If you're concerned, you can use nvm to install an older version of Node, but realistically it probably wont matter.

Thanks for the tip, Abe! I made the change to "node": "12", however, I still get:

Daves-MBP:forms dave$ firebase serve

Sorry I think Abe meant for you to downgrade to either Node 8 or 10 not
upgrade to 12. Firebase does not yet support Node 12.

Using Nvm to change the version of node has a solution

[AAverin]

I am using n and have node set to 8. Still, I get this warning message

@abeisgoat I'm having the same issue trying to run version 10 inside a docker container with only node 10. It throws this at me

Your requested "node" version "10" doesn't match your global version "12"

My package.json looks like:

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "engines": {
    "node": "10"
  },
  ...
}

The project currently is running on node 8 - I had to give up trying to upgrade to node 10 since I thought that my nvm wasn't working. Now I decided to try to do it in a node 10 container and I see that it's not my nvm that was playing with me.

I am also getting this warning with the Firebase Emulator. I have a minimal reproduction at https://github.com/jthegedus/firebase-emulator-warning-reproduction with a GitHub Action demonstrating the issue.

The short of it is this:

• set Node version with asdf and ensure running node --version in a later step produces the version set by asdf
• firebase emulators:exec ... runs and prints
  ⚠ Your requested "node" version "10" doesn't match your global version "12"
• Node 12.19.0 is the default for the GitHub Action runner I am using (ubuntu-latest as seen here - https://github.com/actions/virtual-environments/blob/main/images/linux/Ubuntu2004-README.md)

The emulator runs, but I am unsure if the code is actually running in Node 12 or if this is a just a logging and detection error :shrug:
