It's no longer allowed to omit the '-loader' suffix when using loaders.

You need to specify string-replace-loader instead of string-replace.

module.exports = {
  // ...
  module: {
    loaders: [
      {
        test: /\.js$/,
        loader: 'string-replace-loader',
        query: {
          search: 'jQuery',
          replace: 'window.$'
        }
      }
    ]
  }
}
