所以我一直在尝试设置React Js环境。我面临着babel依赖错误。我知道这个问题很常见，有很多答案，但到目前为止没有一个对我有用。我已经通过互联网搜索解决它，但它仍然显示相同的错误。
这是我得到的错误：

ERROR in ./main.js

这是我的.babelrc

{
    "presets": ["es2015"]
}

webpack.config.js

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
   entry: './main.js',
   output: {
      path: path.join(__dirname, '/bundle'),
      filename: 'index_bundle.js'
   },
   devServer: {
      inline: true,
      port: 8080
   },
   module: {
      rules: [
         {
            test: /\.jsx?$/,

            query: {
               presets: ['es2015', 'react']
            }
         }
      ]
   },
   plugins:[
      new HtmlWebpackPlugin({
