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
