[英]error with webpack - You may need an appropriate loader to handle this file type
[英]webpack ERROR :You may need an appropriate loader to handle this file type
我尝试了很多方法,我搜索了stackoverflow,仍然无法解决。 我是个新手。
错误 :
ERROR in ./public/js/index.jsx
Module parse failed: /home/m/react/r-chat/front/public/js/index.jsx Line 3: Unexpected token
You may need an appropriate loader to handle this file type.
| /*'use strict';*/
|
| import React, { Component, ProTypes } from 'react';
| import { Router, Route, IndexRoute, browserHistory, hashHistory } from 'react-router';
| import Avatar from './components/avatar.jsx';
和我的webpack文件:
var webpack = require('webpack');
module.exports = {
entry: './public/js/index.jsx',
output: {
path: './build',
filename: "bundle.js"
},
module: {
loaders: [
{
test: /\.js?$/,
exclude: /node_modules/,
loader: 'babel',
query: {
presets: ['es2015','react']
}
}
]
},
plugins: [
new webpack.NoErrorsPlugin()
]
};
您需要一个.jsx加载程序。 由于您使用的是.jsx文件,因此.js加载程序将无法正常运行。
更改
{
test: /\.js?$/,
exclude: /node_modules/,
loader: 'babel',
query: {
presets: ['es2015','react']
}
}
至
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: 'babel',
query: {
presets: ['es2015','react']
}
}
您在正在测试js的webpack配置的加载程序中看到了吗? 您需要为JSX添加它,并使用适当的加载器。
babel可以通过babel-loader为您做到这一点: https : //github.com/babel/babel-loader
您需要做的就是将x插入测试,如下所示:
loaders: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: 'babel',
query: {
presets: ['es2015','react']
}
}
]
