这里报错显示的JavaScript 堆内存不足，在 Node 中通过 JavaScript 使用内存时只能使用部分内存（64位系统下约为1.4 GB，32位系统下约为0.7 GB），webpack 编译时就会占用很多的系统资源，如果超出了V8对 Node 默认的内存限制大小，就出现内存溢出问题。V8依然提供了选项让我们使用更多的内存。Node 在启动时可以传递 --max-old-space-size 或 --max-new-space-size 来调整内存大小的使用限制。

2、解决方案：

1.打开angular项目目录node_modules/.bin

2.分别打开ng.cmd和ngc.cmd文件，将最后一行代码修改为绿色框框中的内容即可。

3、再次执行ng build就可以成功了呢。
