Mastering Development

I can’t seem to be able to use hooks in react

I’m starting a new react app. So far, nothing weird has been added. This is how my package.json looks like:

  "name": "client",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.3.2",
    "@testing-library/user-event": "^7.1.2",
    "axios": "^0.19.2",
    "bootstrap": "^4.4.1",
    "fibers": "^5.0.0",
    "jquery": "^3.5.0",
    "moment": "^2.24.0",
    "node-sass": "^4.14.0",
    "popper": "^1.0.1",
    "react": "^16.13.1",
    "react-bootstrap": "^1.0.1",
    "react-dom": "^16.13.1",
    "react-moment": "^0.9.7",
    "react-redux": "^7.2.0",
    "react-router-dom": "^5.1.2",
    "react-scripts": "3.4.1",
    "react-thunk": "^1.0.0",
    "redux": "^4.0.5",
    "redux-devtools-extension": "^2.13.8",
    "sass": "^1.26.5",
    "typescript": "^3.8.3"
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  "eslintConfig": {
    "extends": "react-app"
  "browserslist": {
    "production": [
      "not dead",
      "not op_mini all"
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"

Then I try the most simple of react hooks call within a component:

import React, { useState } from 'react';

const Gallery = () => {
  const [test, setTest] = useState(null);
  return <div>Gallery</div>;

export default Gallery;

But when I try to run it, I get:

Error: Invalid hook call. Hooks can only be called inside of the body
of a function component. This could happen for one of the following
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app See for tips about how to debug and
fix this problem.

The package.json seems to be ok. No duplicate react versions. React is 16.8+. And the component is a functional component, not a class-based one. What could I be missing?

NOTE: When I try to run the “npm ls react” suggested in the documentation, I get no versions listed. react-dom appears correctly. Could this be the cause? And if so, any ideas of how to fix it?
