本项目用的是angular6搭建，用动态组件的形式来显示页面，之前遇到过因为内存溢出而导致无法aot的问题，

Angular4以上的该方法都适用

解决方法：手动改写内存上限

修改目录: my-project/node_modules/.bin 找到 ng.cmd :

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe" --max_old_space_size=8192 "%~dp0\..\@angular\cli\bin\ng" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node --max_old_space_size=8192  "%~dp0\..\@angular\cli\bin\ng" %*
)

修改目录: my-project/node_modules/.bin 找到 ngc.cmd :

@IF EXIST "%~dp0\node.exe" (
 "%~dp0\node.exe" --max_old_space_size=8192 "%~dp0\..\._@angular_compiler-cli@4.0.1@@angular\compiler-cli\src\main.js" %*
) ELSE (
 @SETLOCAL
 @SET PATHEXT=%PATHEXT:;.JS;=;%
 node --max_old_space_size=8192 "%~dp0\..\._@angular_compiler-cli@4.0.1@@angular\compiler-cli\src\main.js" %*
)

至于到底是什么原因导致的内存溢出，还不清楚，只是有如下猜测：

1）文件过多；

2）订阅数据没有销毁占用内存，（看了下订阅的数据很少，应该不是的）；

3）因为所有的组件都在一个根目录下（上面说了，用的动态组件没用路由），导致需要编译的组件过多？

暂时还不清楚只能先用设置内存上限的方法来解决，有大神的话望不吝指教；

还有一个问题就是用动态组件的方式，组件都在根目录下，会导致首次加载的时间过长。有奇思妙想请告诉我，哈哈

同时package的时候也需要修改打包时候的内存
