Question

我正在使用IONIC 3构建应用程序，而在构建生产应用程序时却遇到了JS问题。

我使用代码ionic cordova build ios --prod 并且出现跟随错误

我在节点上添加了--max_old_space_size = 4096，但遗憾的是它只会减慢显示错误的速度。我能做什么？

我完全遵循此环境here，但是现在在firebase上又停止了。它只是停下来而没有说什么。

可以增加节点的最大内存大小：

在终端控制台中：

// Desctructuing:       Actual object/array:
const [{                // [{
  content: {            //   "content": {             
    tabs: [{            //     "tabs": [{
      sections: foo     //       "name": "Overview", "id": 1, "sections": {...}
    }]                  //     }, ...]
  }                     //   }
}] = obj;               // }, ...]

如果使用 Windows ：

export NODE_OPTIONS=--max_old_space_size=8096

运行ionic build --prod之前

我遇到了同样的问题，这解决了我的问题。信用：https://github.com/ionic-team/ionic/issues/16868

离子Cordova构建ios --prod使JavaScript堆内存不足
