Answer 2

There is a mistake in your usage method. There are many ways to use babel. The most common ones are .babelrc files, or the require('babel') method. You configured .babelrc but you did not use babel to compile you. index.js file, however the import syntax is not implemented in your existing version of node, so an error is reported
