【问题描述】：

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

我使用代码ionic cordova build ios --prod 并出现以下错误

我已经在节点上添加了 --max_old_space_size=4096，但遗憾的是它只是减慢了错误的出现。我能做什么？

更新

我完全遵循了这个环境here，但现在又在 firebase 上停止了。它只是停下来，一言不发。

@pmkro 我一直在尝试大多数此类问题，但似乎最大的问题是 firebase。现在正试图挖掘它。

【解决方案1】：

节点的最大内存大小可以增加：

在终端控制台：

export NODE_OPTIONS=--max_old_space_size=8096

如果使用 Windows：

set NODE_OPTIONS=--max_old_space_size=8096

在运行 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
