Question

我在 React 项目中使用 redux 表单，这是初始化了 redux 表单的应用程序组件：

import { Field, reduxForm } from 'redux-form';

const onSubmit = (values) => {
    alert(JSON.stringify(values));
};
function App(props) {
    return (
        <div className="App">
            <form onSubmit={props.handleSubmit}>
                <div>
                    <label htmlFor="firstName">First Name</label>
                    <Field name="firstName" component="input" type="text" />
                </div>
                <div>
                    <label htmlFor="lastName">Last Name</label>
                    <Field name="lastName" component="input" type="text" />
                </div>
                <div>
                    <label htmlFor="email">Email</label>
                    <Field name="email" component="input" type="email" />
                </div>
                <button type="submit">Submit</button>
            </form>
            {props.number}
            <button onClick={() => props.callAction()} />
        </div>
    );
}


App = reduxForm({
    form: 'contact',
    onSubmit
})(App);

但是我在控制台中收到这个错误，它来自 react strict 模式：

 Using UNSAFE_componentWillReceiveProps in strict mode is not recommended and may indicate bugs in your code.
* Move data fetching code or side effects to componentDidUpdate.
* If you're updating state whenever props change, refactor your code to use memoization techniques or move it to static getDerivedStateFromProps. Learn more at:state

Please update the following components: Field, Form(App)

我该如何解决这个错误？

至于apokryfos commented, there seems to be an open issue这个。我要么等待 redux-form 的作者发布更新，要么寻找替代库（因为这个库的作者似乎说在大多数情况下我们不应该使用它）。
