  • Did you install the Firebase CLI? If you did, make sure you have the updated version. You can run npm install -g firebase-tools in your project directory

    It looks like you forgot to run npm install (or npm install firebase) before deploying. See the last line of the terminal.

  • Also, make sure you're running npm install from the functions subdirectory of your project.

Cannot find module 'firebase-functions' means that you need to install packages. In your project directory run

$ cd functions
$ npm install

then return back and fire!

$ firebase deploy

Happy coding!

By default, the firebase dependency isn't in your functions/package.json. Instead, you'll find it lists firebase-admin, the specialized server-side Firebase SDK which is the one we recommend using.

If you really do want to use the firebase client-side SDK instead of firebase-admin, you'll want to run npm install --save firebase in your functions/ directory. You should then have a line in your functions/package.json that looks a bit like this:

{
  ...
  "dependencies": {
    "firebase": "^3.7.2",
    ...
  },
  ...
}

    In my case, following the procedure above, the package.json did get updated with firebase dependency but I'm still getting the error: error TS2307: Cannot find module 'firebase' or its corresponding type declarations when I run firebase deploy. Can you tell me how to fix it?

Although this is coming late, but it's for those who might face the same issue. This worked for me. I added this to my package.json file in folder function.

 {
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "dependencies": {
    "firebase-admin": "~5.2.1",
    "firebase-functions": "^0.6.2",
    "mkdirp": "^0.5.1",
    "mkdirp-promise": "^4.0.0"
  },
  "private": true
}

Then run: npm install in folder function

Clean up node_modules,

rm -rf package-lock.json
rm -rf node_modules

Update functions/package.json file with latest or compatible versions of dependencies with your node version and run npm install from functions folder.

Try firebase deploy now. Should be good!

In my case, some of the cached packages were installed with root permission. So when I tried to deploy with only npm run deploy , was not finding the packages.

sudo npm run deploy worked for me.
