babel-node es6 “Modules aren't supported in the REPL”

Question

babel-preset-es2015 is installed, and is OK with es6 feature just like below let a = 2;.
But can not work with es6 modules feature import

Answer 1

Got it from the official doc：http://babeljs.io/docs/usage/cli/

ES6-style module-loading may not function as expected
Due to technical limitations ES6-style module-loading is not fully supported in a babel-node REPL.
