Question

npm start在intellij的终端中正常工作。

但是在常规shell终端

中运行时，它在下面的行失败了

 const {
   choosePort,
   createCompiler,
   prepareProxy,
   prepareUrls,
 } = require('react-dev-utils/WebpackDevServerUtils');

上面的代码位于start.js内，npm start运行node start.js

我猜intellij默认使用es6 我怎样才能在intellij之外模仿？

以下是错误

$ npm start

> bold-chat-admin@0.1.0 start /Users/eugenekim/Documents/boldchatting.web
> PORT=3000 node scripts/start.js

IDEA本身不会运行代码 - 它是使用您在 NPM 运行配置中选择的Node.js解释器运行的（通常与Preferences | Languages & Frameworks | Node.js and NPM中设置的相同，除非您选择一个明确的另一个）。看起来用于在IDEA中运行脚本的Node.js解释器本身支持ES6解构，而终端中使用的节点5.5则不支持。有关不同节点版本支持的ES6技能的信息，请参阅http://node.green/

npm start ..在intellij中运行正常，但在终端没有？
