網(wǎng)上找了很多方法，裝了插件還是不行babel-plugin-transform-runtime babel-runtime
.babelrc如下

{
    "presets": ["es2015","stage-3"],
    "plugins": [[
        "transform-runtime",
        {
          "helpers": false,
          "polyfill": false,
          "regenerator": true,
          "moduleName": "babel-runtime"
        }
      ]]
}

這是開發(fā)依賴
