Question

Error:

  TypeError: (0 , _react.useState) is not a function

Answer 1

Error:

  TypeError: (0 , _react.useState) is not a function

My current react versions:

   "react": "^16.7",
   "react-dom": "^16.7",

src/App.js:

  import {memo, useState} from 'react'
  export default memo(() => {
     useState(false)
     return 'OK'
  })

src/App.test.js:

   import React from 'react'
   import App from './App'
   import renderer from 'react-test-renderer'
   it('renders without crashing', () => {
        const tree = renderer.create(<App />).toJSON()
        expect(tree).toMatchSnapshot()
   })

How to resolve this issue?

Questing posted 3 years ago but maybe sommeone is sufering with the same problem) In my case the mistake was in the imports. My IDE imported the useState hook from import 'react\/cjs\/react.development' and it dosen't work on production.
