node.js - Could not find a declaration file for module 'firebase-tools', despite installing and requiring

Question

I have tried several different methods for installing Firebase-Tools

npm install firebase-tools

npm i --save-dev @types/firebase-tools

npm install -g firebase-tools

But still when I add:

const firebase_tools = require("firebase-tools")

to my project, I get an error when deploying:

Could not find a declaration file for module 'firebase_tools'

in my Visual Studio Code.

I have tried following the below link, but their response was to use require, which I already am.

Answer 1

Have you tried:

npm install -s firebase-tools

Since your error happens when deploying, I am led to believe your package.json may not contain the firebase-tools dependency. You need to run the npm install command with the -s flag in order for it to be saved in the package.json
