when I want to deploy my project with firebase, I encountered the nodeJS version problem and it troubled me for many days. when I apply the command "firebase deploy --only functions", then it reminds me that: 

i  deploying functions
Running command: npm --prefix functions install

Error: Error occurred while parsing your function triggers.

Error: The module 
was compiled against a different Node.js version using
NODE_MODULE_VERSION 48. This version of Node.js requires
NODE_MODULE_VERSION 57. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).

Having trouble? Try firebase deploy --help

my node version is v8.11.3 my npm version is 6.2.0

Anyone knows how to solve it?? Thank you very much!!!

  • I tried all the solution I can find like "npm update" "npm install", but they all don't work. Also, I tried many other versions of nodejs but no one can solve this problem. – Lei Zhao Aug 02 '18 at 00:02
  • Try `npm rebuild`, or barring that, `rm -rf node_modules` in your functions directory and run `npm install` again. – Michael Bleigh Aug 02 '18 at 00:37
  • Don't show images of errors and code. Copy the text into a the question itself so it's easy to read and search. – Doug Stevenson Aug 02 '18 at 01:07
  • I tried "npm rebuild" and "rm -rf node_modules", also "npm install". They all don't work. Is there other reason which can cause this problem?? – Lei Zhao Aug 02 '18 at 07:22

Was running into the same issues. Updated my Node JS version to v8.16.0, then within my Functions / package.json I added the nodeJS engine version:

 "engines": { "node": "8" },

I am now able to deploy my functions.
