配置是這樣的：

var path = require('path');

var htmlWebpackPlugin=require("html-webpack-plugin");

module.exports={

entry:"./src/app.js",

output:{

path:path.resolve(__dirname, './dist'),

filename:"js/[name]-bundle.js"

},

module:{

loaders:[

{

test:/\.js$/,

loader:"babel-loader",

exclude:"./node_modules/",

options:{

"presets":["env"]

}

}

]

},

plugins:[

new htmlWebpackPlugin({

filename:"index.html",

template:"index.html",

inject:"body"

})

]

}

可是還是報錯如下：
