vue 打包npm run build报错Unexpected token: punc (() [static/js/0.739c7d2b56384f8c9c1d.js:7425,8]

同事电脑可以对工程进行打包，我的电脑就报错，研究了好久终于找到了原因。

在工程项目下建.babelrc文件

{
    "presets": [
      ["env", {
        "modules": false,
        "targets": {
          "browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
        }
      }],
      "stage-2"
    ],
    "plugins": ["transform-runtime"],
    "env": {
      "test": {
        "presets": ["env", "stage-2"],
        "plugins": ["istanbul"]
      }
    }
}
