内存溢出了。
解决办法，启动时加大内存，
vue-cli2：
npm run dev 和 npm run build 直接在前面加上--max_old_space_size=4096

 "scripts": {
      "start": "npm run dev",
    "dev": "node --max_old_space_size=4096 build/dev-server.js",
    "build": "node --max_old_space_size=4096 build/build.js",
  },

vue-cli3：
scripts中添加一句指令
安装两个npm包 ： increase-memory-limit 和cross-env
安装完成后，先执行一次 npm run fix-memory-limit，然后npm run serve启动即可

"scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    
    "fix-memory-limit": "cross-env LIMIT=4096 increase-memory-limit",
  },

注：最好还是检查一下代码之间的相互引用，导致内存消耗过高！
