“You may need an appropriate loader to handle this file type” with Webpack and Babel

[AlexQianjin]

There is a webpack build error "You may need an appropriate loader to handle this file type" when I use the latest webpack and babel for now.
And here is my solution. I replace the regular expression from /.js?$/ to /.(js|jsx)/ in the babel configuration of module loaders. I use VS Code as the editor, and the "?" is highlighted in it. I don't know why. But it works fine after I made this change.

webpack config

module:  {  
        loaders: [{
            test: /\.(js|jsx)$/,
            loader: 'babel-loader',
            exclude: /node_modules/,
            query:
            {
                presets:['es2015', 'stage-2', 'react']
            }
        }]
    }

package.json
