我正在尝试使用Webpack进行基本的React设置,但是当前正在获取这个控制台错误,我试图呈现html。反应 - 模块构建失败
不知道为什么,有什么想法?
模块构建失败:语法错误:
的Javascript
import React from "react";
import { render } from "react-dom";
class App extends React.Component {
render() {
return (
<p>h</p>
)
}
}
render(<App/>, document.getElementById('main'));
的WebPack配置
const webpack = require('webpack');
const nodeEnv = process.env.NODE_ENV || "production";
module.exports = {
devtool: "source-map",
entry: {
filename: "./index.js"
},
output: {
filename: "build/bundle.js"
},
module: {
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader',
query: {
presets: ['es2015-native-modules']
}
}
]
},
plugins: [
new webpack.optimize.UglifyJsPlugin({
compress: { warnings: false },
output: { comments: false },
sourcemap: true
}),
new webpack.DefinePlugin({
'process.env': { NODE_ENV: JSON.stringify(nodeEnv
)}
})
]
}
的package.json
{
"name": "joe-react",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"build": "webpack --progress --watch"
},
"author": "",
"license": "ISC",
"dependencies": {
"react": "^15.4.2",
"react-dom": "^15.4.2"
},
"devDependencies": {

"babel-loader": "^6.4.1",
"babel-preset-es2015-native-modules": "^6.9.4",
"webpack": "^2.3.2"
}
}
感谢你。对于任何想知道我卸载了'babel-preset-es2015-native-modules'并安装了'babel-preset-es2015'的人,我的webpack.config.js改为'es2015'而不是'es2015-native-modules'。 我还安装了'babel-preset-react',并在webpack.config.js中的预设中添加了该选项。 –
