使用连接时出错(react-redux 库的功能) [英] error when using connect (function of the react-redux library)
问题描述
我有一个组件类,我使用 react-redux 来连接 redux 存储,但是当我尝试将组件传递给 connect 函数时出现错误.
I have a component class that I am using react-redux to connect the redux store, but I am getting an error when I try to pass the component into the connect function.
_react.default.memo 不是函数.(在 '_react.default.memo(ConnectFunction),'_react.default.memo' 未定义)
_react.default.memo is not a function. (In '_react.default.memo(ConnectFunction), '_react.default.memo' is undefined)
wrapWithConnect C:\Users\SESA506797XmobileApp Gatherman\node 模块 react-redux\lib\components connectAdvanced.js: 339:45

这里是调用connect的类的内容
Here is the content of the class in which connect was called

import React from 'react'
import { StyleSheet, View, ActivityIndicator, ScrollView, Text, Image }
from 'react-native'
import { getFilmDetailFromApi, getImageFromApi } from '../API/TMDBApi'
import { connect } from 'react-redux'
class FilmDetail extends React.Component {
constructor(props) {
super(props)
this.state = {
film: undefined,
}
}
componentDidMount() {
getFilmDetailFromApi(this.props.navigation.state.params.idFilm).then(data => {
this.setState({
film:data,
isLoading: false
})
})
}
_displayFilm(){
const film = this.state.film
if(film != undefined){
return(
<ScrollView style={styles.scrollView_container}>
<Image
style = {styles.image}
source = {{uri: getImageFromApi(film.backdrop_path)}}
/>
<Text style={styles.title_text}>{film.title}</Text>
<Text style={styles.description_text}>{film.overview}</Text>
<Text style={styles.default_text}>Note : {film.vote_average} / 10</Text>
</ScrollView>
)
}
}
render() {
return (
<View style={styles.main_container}>
{this._displayFilm()}
</View>
)
}
}
const styles = StyleSheet.create({
main_container: {
flex: 1
},
})
const mapStateToProps = (state) => {
return state
}
export default connect(mapStateToProps)(FilmDetail)

推荐答案
前阵子遇到了和你一样的问题.我更新到最新的 React 版本:
Had a while ago what I think is the same problem as you. I updated to the latest React version with:
npm install react@latest
然后安装了 0.4.0 版的 react schedule 包:
Then installed version 0.4.0 of the react schedule package with:
npm i schedule@0.4.0 --save-dev
并用
npm i react-redux@6.0.1
至少目前我的问题已经解决了,希望对你有用.
at least for the moment my problem is solved, hope it works with yours.
