Node.js不支持ES6导入和导出

Question

I'm building a project using WebStorm 2016.2.2. I use version 6.6.0 of Node.js. I have set the JavaScript version to ES6, but I get "unexpected token" errors for both import and export keywords. I don't get errors for Lambda expressions BTW.

Why do I get this error? Am I doing something wrong or Node just does not support import and export without Babel (even though I have set the JavaScript version to ES6)?

Answer 1

Node.js supports CommonJS modules, however support for ECMAScript modules is currently being designed .

In the meantime, you'll have to use Babel to transform ECMAScript modules to CommonJS. Try using a minimal preset for Node.js builds, like babel-preset-node6 .

Answer 2

es6 does support import and export, node 6 does not support es6 import/export up till now as far as I know.
