解决办法

package.json 增加 --max_old_space_size=8192

"scripts": {
    "dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
    "start": "npm run dev",
    "lint": "eslint --ext .js,.vue src",
    "build": "node  build/build.js"
  },

改为

"scripts": {
    "dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
    "start": "npm run dev",
    "lint": "eslint --ext .js,.vue src",
    "build": "node --max_old_space_size=8192 build/build.js"
  },
