解决-请阅读更新2
你好,我在工具包中出现了这个错误,其中包含了map传单地图。
这就像github模块的例子,但我不知道什么是问题!我想这和SSR有问题
react版本: 16.x和工具包

import React from 'react';
import { Map, TileLayer, Marker, Popup } from 'react-leaflet';
import withStyles from 'isomorphic-style-loader/lib/withStyles';
import s from './Home.css';
class Home extends React.Component {
constructor(props){
super(props);
this.state = {
lat: 51.505,
lng: -0.09,
zoom: 13,
}
}
render() {
const position = [this.state.lat, this.state.lng]
return (
<Map center={position} zoom={this.state.zoom}>
<TileLayer

/>
<Marker position={position}>
<Popup>
A pretty CSS3 popup. <br /> Easily customizable.
</Popup>
</Marker>
</Map>
);
}
}
export default withStyles(s)(Home);更新2由我自己解决
import React from 'react';
import withStyles from 'isomorphic-style-loader/lib/withStyles';
import leafletCss from '!isomorphic-style-loader!css-loader?modules=false!leaflet/dist/leaflet.css'; //if use isomorphic-style-loader
import s from './GenerateMap.css';
let RL = false;
let Map = false;
let TileLayer = false;
let Marker = false;
let Popup = false;
if (process.env.BROWSER) {
RL = require('react-leaflet');
Map = RL.Map;
TileLayer = RL.TileLayer;
Marker = RL.Marker;
Popup = RL.Popup;
}
class GenerateMap extends React.Component {
render() {
const position = [51.505, -0.09]
return (
<div className={s.root}>
{process.env.BROWSER && (
<Map style={{width:'100%',height: '500px'}} center={position} zoom={13}>

<Marker position={position} icon=''>

)}
</div>
);
}
}
export default withStyles(s, leafletCss)(GenerateMap);发布于 2018-07-10 13:01:54
从堆栈跟踪中,我看到react-leaflet使用的是作为React一部分的createContext()。这仅在反应16.3中可用。
您检查了正在使用的版本 of react-leaflet吗?您可能正在使用具有依赖关系的版本来响应16.3。您可以尝试将react-leaflet降级到1.9.1,看看它是否有效。
最新答复:
没有定义window是一个错误,很可能发生在您的代码试图访问全局变量window时,只有在代码在浏览器中运行时才定义这个变量(而不是window)。检查您的代码,看看是否因为您的代码发生了该错误。如果它是由react-leaflet引起的,请阅读下面.
经过更多的搜索后,react-leaflet的构建似乎并没有考虑到服务器端呈现。您可以尝试检查反应-传单-普遍来实现它。如果所有这些都失败了,您可能需要为传单构建自己的包装器来实现这一点。
