react_dom__WEBPACK_IMPORTED_MODULE_1___default.a.createRoo。

Question

当使用实验版的react-dom、react-relay和react时，我得到了如下错误信息

react_dom__WEBPACK_IMPORTED_MODULE_1___default.a.createRoo

TypeError: useTransition is not a function or its return value is not iterable

Answer 1

它可以通过使用

unstable_createRoot和unstable_useTransition。

import React from 'react'
import ReactDOM from 'react-dom'
import './index.css'
import App from './App'
import * as serviceWorker from './serviceWorker'

const rootEl = document.getElementById('root')

// @ts-ignore
ReactDOM.unstable_createRoot(rootEl).render(<App />)

// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.
serviceWorker.unregister()
