Error: Cannot find module './lib/source-map-generator'

Question

I just cloned a repository ( a React Native project) from Github, ran npm install and then npm start.

Then instead of running the metro bundler, it throws the following error:

node:internal/modules/cjs/loader:936
  throw err;
  ^

}

Does anybody know how to solve the above issue?

Thanks in advance.

Anybody knows why this happened? (out of curiosity). It happened to me with Angular. Hadn't touched the project in a few days (while still serving it) and out of nowhere this happened... — Martin Carre

Try removing node_modules and repeat the npm install or yarn.

If that still doesn’t work, maybe try removing package-lock.json/yarn.lock and repeat the above.

npm install source-map worked for me (as per @Muhammad Zakaria's comment above). I had this error with Angular.

I have deleted the node_modules and package.lock.json, after that I have done the npm install and it resolved the issue for me.
