Cannot find module 'axios'

Question

I am coding a small program for Firebase Functions, using node.js. I always install my node modules using npm and i also installed axios using npm only.

However when I do firebase deploy I get this error:

This is my package-lock.json

{
  "requires": true,
  "lockfileVersion": 1,
  "dependencies": {
    "axios": {
      "version": "0.19.0",
      "resolved": "https://registry.npmjs.org/axios/-/axios-0.19.0.tgz",

      "requires": {
        "follow-redirects": "1.5.10",
        "is-buffer": "^2.0.2"
      }
    },
    "debug": {
      "version": "3.1.0",
      "resolved": "https://registry.npmjs.org/debug/-/debug-3.1.0.tgz",

      "requires": {
        "ms": "2.0.0"
      }
    },

      "requires": {
        "debug": "=3.1.0"
      }
    },
    "is-buffer": {
      "version": "2.0.4",
      "resolved": "https://registry.npmjs.org/is-buffer/-/is-buffer-2.0.4.tgz",
      "integrity": "sha512-Kq1rokWXOPXWuaMAqZiJW4XxsmD9zGx9q4aePabbn3qCRGedtH7Cm+zV8WETitMfu1wdh+Rvd6w5egwSngUX2A=="
    },
    "ms": {
      "version": "2.0.0",
      "resolved": "https://registry.npmjs.org/ms/-/ms-2.0.0.tgz",
      "integrity": "sha1-VgiurfwAvmwpAd9fmGF4jeDVl8g="
    }
  }
}

When I remove const axios = require('axios'); from my index.js, the rest of my code compiles and works just fine.

Any idea what is going on?

Thank you!

Answer 1

Looks like you are missing axios dependency in your package.json file.

Go to the functions directory and install axios. This will declare the axios dependency in the package.json for you. It works for me.

npm install axios --save

Redeploy your Cloud Function for Firebase using:

firebase deploy

Answer 2

Command prompt then go to your folder and npm install axios. Finally, run the code. It worked for me
