Baidu once, someone said because
webpack version inconsistency results. So reinstall

npm install webpack --save-dev

There are many warnings when performing this step

npm notice save webpack is being moved from dependencies to devDependencies
npm WARN [email protected] requires a peer of [email protected] || 3 but none is installed. You must install peer dependencies yourself.
npm WARN [email protected] requires a peer of [email protected]>=1.8.0 but none is installed. You must install peer dependencies yourself.
npm WARN [email protected] No description
npm WARN [email protected] No repository field.

The babel-Loader version requires a more advanced WebPack, so execute the following statement to install version 3.0

npm install [email protected] --save-dev

Execute the WebPack and it will run successfully.
