我在构建 Ionic 3 应用程序的生产版本时收到以下错误。 ">致命错误：接近堆限制的无效标记压缩分配失败 - JavaScript 堆内存不足" 为了重现此问题，我复制了整个项目并在复制的项目中进行了生产构建，但令人惊讶的是生成了生产构建。我无法找到导致此问题的确切原因。
我正在附加我的包.json

我在我的项目中不断遇到这个问题，但在复制的项目中却没有。这两个项目都有相同的 package.json 和代码。
当应用程序消耗的内存多于默认分配的内存时，会发生这种情况。 您可以做两件事
- 重构您的项目并尝试优化它，删除所有不必要的库和导入，这将在构建捆绑包时减少 angular 编译器的负载。
- 第一点在很多时候没有帮助，您可能需要一个快速的解决方案，因此您可以使用
node --max_old_space_size=8192 $which(ionic-app-scripts) build或node --max-old-space-size=8192 ./node_modules/@ionic/app-scripts/bin/ionic-app-scripts.js build来增加堆内存分配
对于它在复制项目中工作的点 - 可能是您的系统资源在那个时候并不那么忙
