Please see below code and attached screen shot of the issue i am having. Webpack is failing when ever i try to re build the files. Can someone please advise of what that issue could be. I'm currently using all the latest libraries.
/*webpack.config.js*/
module.exports = {
entry: {
main: [
'./src/main.js'
]
},
output: {
filename: './public/[name].js'
},
module: {
loaders: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: 'babel'
}
]
}
}
/*App.jsx*/
import React from 'react';
class App extends React.Component {
constructor() {
super();
this.state = {
messages: [
'hi there how are you ?',
'i am fine, how are you ?'
]
}
}
render() {
var messageNodes = this.state.messages.map((message)=> {
return (
<div>{message}</div>
);
});
return (
<div>{messageNodes}</div>
);
}
}
export default App;
/*main.js*/
import React from 'react';
import ReactDOM from 'react-dom';
import App from './components/App.jsx';
ReactDOM.render(<App/>, getElementById('container'));
/*index.html*/
<!DOCTYPE html>

推荐答案
已解决.答案是安装预设npm i --save babel-preset-env babel-preset-react.然后在加载器的 webpack.config.js 中添加另一个密钥:query: {presets: ['env', 'react'] }.应该很好.
It was solved. The answer was in installing presets npm i --save babel-preset-env babel-preset-react. Then adding another key in the webpack.config.js, in the loader: query: {presets: ['env', 'react'] }. Should be good to go.
