angular Last few GCs JavaScript heap out of memory

angular再运行项目时，出现如下问题：

<--- Last few GCs --->

解决方案：

1.打开你的终端（vsCode）或者 Terminal（WebStorm）

2.执行以下命令设置--max_old_space_size值，单位M（8192=8G)

Windows 当前应用程序有效（在vscode或cmd设置，哪里设置的哪里有效，关闭后设置取消，下次需重新在应用程序中设置）：

set NODE_OPTIONS=--max_old_space_size=8192

Windows 永久有效(仅用户级别，cmd中运行)：

setx NODE_OPTIONS --max-old-space-size=8192

Windows 永久有效(系统级别)

在环境变量窗口中编辑系统级别的环境变量。新增配置：

name:NODE_OPTIONS

value:--max-old-space-size=8192

我的貌似每次都要在vscode的cmd下运行一下，否则还是会报错：
