Cannot find module 'react' from 'Accordion.js'

After running my searchapp, accessing the searchapp command directory using "cd searchapp", and running a test module using "npm test", I get the following error:

> react-scripts test --env=jsdom
 FAIL  src\App.test.js
  ● Test suite failed to run

    Cannot find module 'react' from 'Accordion.js'

      at Resolver.resolveModule (node_modules/jest-resolve/build/index.js:179:17)
      at Object.<anonymous> (../node_modules/react-bootstrap/lib/Accordion.js:21:14)

My App.test.js file is as follows, for clarification:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

it('renders without crashing', () => {
  const div = document.createElement('div');
  ReactDOM.render(<App />, div);

Why is the test not passing in Node's npm command prompt? Any help would be appreciated.

I have react as a dependency in the package.json file:

  "name": "searchapp",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.2.0",
    "react-dom": "^16.2.0",
    "react-scripts": "1.1.1"

  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"

Try to delete your node_modules folder, and install all the packages again.

You will have to do the npm command at the main directory.

npm install
