我是一个新手,正在使用webpack、babel loader和eslint。我试图编译一个非常基本的应用程序,但是我遇到了一个奇怪的语法错误,我无法解决。
这是我的index.js文件,我在这里遇到了编译错误。
这是我的index.js文件,我在这里遇到了编译错误。
const store = configureStore()
render(
<Router>
<Root store={ store } />
</Router>,
document.getElementById('console_root')
)
这是我得到的错误:
ERROR in ./src/index.js
Module build failed: SyntaxError: Unexpected token (19:2)

18 | render(

| ^
20 | <Root store={ store } />
21 | </Router>,
22 | document.getElementById('console_root')
npm ERR! code ELIFECYCLE
npm ERR! errno 2
这是我的webpack.config.js文件
var webpack = require('webpack')
var path = require('path')
module.exports = {
entry: {
main: path.resolve(__dirname, 'src', 'index.js')
},
resolve: {
extensions: ['*', '.js', '.jsx']
},
output: {
path: path.resolve(__dirname, '..'),
publicPath: '/',
filename: 'bundle.js'
},
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: ['babel-loader', 'eslint-loader']
},
{
test: /\.scss$/,
use: ['style-loader', 'css-loader', 'sass-loader']
}
]
},
plugins: [
new webpack.optimize.UglifyJsPlugin({
compress: {
warnings: false
}
}),
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: '"production"'
}
})
]
}
这些是我的依赖项:
"dependencies": {
"material-ui": "^1.0.0-beta.26",
"material-ui-icons": "^1.0.0-beta.17",
"prop-types": "^15.6.0",

有什么想法我做错了什么吗?
render
函数是来自ReactDOM
吗?因为初始化应该是ReactDOM.render()
而不是来自component
包的普通render()
