我正在Angular-cli项目中创建传单 map。由于 map图块是栅格 map，因此它们会本地存储在“资产”文件夹中。问题是，当我具有许多缩放级别的 map时，我拥有超过28万张图像，其大小约为1.1 GB，并且会变得更大。

当我使用ng serve这里是控制台输出（卡住@资产优化）：

我尝试使用： node --max_old_space_size=8192 --optimize_for_size --max_executable_size=4096 --stack_size=4096，但没有任何区别。

1-还有其他方法可以避免优化所有资产文件夹吗？是否是我所认为的问题的根源，因为该项目在添加更多的传单图块图像之前运行顺利。

2-是否有解决此问题的解决方法？

更新：Angular-cli存储库中 有一个与此问题相关的未解决问题。
