TypeError dispatcher.useState is not a function when using React Hooks

You may get same error when using jest. So to fix the error I had to update react-test-renderer to have the same version as react and react-dom

yarn add -D react-test-renderer@next

Or

npm i react-test-renderer@next

All react, react-dom and react-test-renderer should contain same version

"react": "^16.7.0-alpha.0",
"react-dom": "^16.7.0-alpha.0",
"react-test-renderer": "^16.7.0-alpha.0"

There could be many reasons, and most are due to version incompatibilites or using a ^ in package.json:

1. Ensure react and react-dom are of the same version

Ensure that you have also updated the react-dom package and it is of the same version as react. In general react and react-dom should always be the same version in package.json as the React team updates them together.

If you want to install React 16.7.0-alpha.2, check that you are not using the ^ as you will install 16.7 instead, which doesn't have hooks.

Example package.json:

{
  ...
  "dependencies": {
    "react": "16.8.4", // Make sure version is same as react-dom
    "react-dom": "16.8.4",
    ...
  }
}

2. react-test-renderer is of the same version as react and react-dom

If you are using Jest, ensure that react-test-renderer is of the same version as react and react-dom:

Example package.json:

{
  ...
  "dependencies": {
    "react": "16.8.4",
    "react-dom": "16.8.4",
    "react-test-renderer": "16.8.4",
    ...
  }
}
