Create-react-app: why I can't use bundle-loader like this?

[famanoder]

import LazyLogin from 'bundle-loader?lazy&name=[name]!./views/Login.js';

when I use bundle-loader like this ,some errors occured ! I had found some way and couldn't solve it .
I need some help ,and what should I do ?

Unexpected '!' in 'bundle-loader?lazy&name=[name]!./views/Login.js'. Do not use import syntax to configure webpack loaders import/no-webpack-loader-syntax

Webpack loaders are not supported by Create React App.

Moreover, you don’t need bundle-loader to implement lazy loading.
It is already supported out of the box with dynamic import().
