.babelrc配置
{
  "presets": ["es2015", "stage-0"]
}

.babelrc配置

{

"presets": ["es2015", "stage-0"]

}

解决

安装 ES 标准

npm i -D babel-preset-es2015

1	npm i -D babel-preset-es2015

再次运行

PS H:\project\nodejs\demo\learn\chapter3\3.11> babel .\test.js
"use strict";

var a = 1,
    b = 2,
    c = 3;

PS H:\project\nodejs\demo\learn\chapter3\3.11> babel .\test.js

"use strict";

var a = 1,

b = 2,

c = 3;
