cannot find module "firebase-functions"

Question

I imported and downloaded: firebase-functions and firebase-admin using npm i <package> but it give me a lint error like: cannot find module "firebase-functions". I also restarted vscode, but problem persists..

---

Could it be problem with webpack or tsconfig?

Answer 1

npm install firebase-functions
npm install firebase-admin

Answer 2

You can try the following commands:

firebase use --add
firebase init functions

To get your project. Sometimes, its a permission problem. What you can try is creating a new account on your computer and doing the same commands, that almost always works.
