vue.js reports an error because the project does not recognize the es6 expansion operator. The solution is to download the es6 dependencies through the "cnpm install babel-preset-es2015 --save-dev" method.

Why does using the... operator in vue.js report an error?

vue.js reports an error when using the... operator: the project does not recognize the es6 expansion operator. The solution is very simple.

Solution:

// 第一步
cnpm install babel-plugin-transform-object-rest-spread
// 第二步 看一下你的 .babelrc 里面是否有识别es6语法的配置
{
 "presets": [
  ["env", {
   "modules": false,
   "targets": {
    "browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
   }
  }],
  "stage-2"
 ],
 "presets": [
  ["es2015", { "modules": false }]
 ],
 "plugins": ["transform-object-rest-spread"]
}

After doing both, I found that another error was reported. The reason is that you only configured it. But there is no download of es6 dependencies

Just need to download

cnpm install babel-preset-es2015 --save-dev

and it will be ok!
