新手運行webpack 報錯： unknown property 'loaders'.

webpack.config.js代碼：
var webpack = require('webpack');
var path = require("path");
module.exports = {
        entry: './src/app.js',
        output: {
            path: path.resolve(__dirname,'./bin'),
            filename: 'app.bundle.js'
        },
        module: {
          loaders: [
             {
               test: /\.js$/,
               exclude: /(node_modules|bower_components)/,
               loader: 'babel-loader',
               query: {
                   presets: ['es2015']
                }
          }
        ]
    }
    

執(zhí)行webpack命令的時候就報錯：

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.configuration.module has an unknown property 'loaders'. These properties are valid:

我查看了webpack -v 是3.2.0
我把module下面的loaders字符換成rules又不會報錯了。
我上網(wǎng)查了下，好像是webpack1，和webpack2的配置不同，
不知道我電腦是不是裝了webpack1和webpack2，我查看過其它項目都是用的rulse，沒有l(wèi)oaders，是不是webpack1不怎么用了，還是怎么的？
