Windows10中的我的Angular应用程序，在使用ng build --prod时引发获取错误。这适用于ng build。
我的项目使用assets文件夹中的4个json文件。一个文件大小是21 MB，另外三个文件大小为4-5 MB。如果我删除了21MB的文件，说明它工作正常。
PS D:ProjectPathProject1> ng build --prod
Option "extractCss" is deprecated: Deprecated since version 11.0. No longer required to disable CSS extraction for HMR.

我在Angular.json中也添加了这个解决方案。无效的标记压缩接近堆限制分配失败-角度中JavaScript堆内存不足也试过这个https://www.npmjs.com/package/increase-memory-limit我已经在cmd中执行了setx NODE_OPTIONS --max_old_space_size=10240，但仍然无法工作。
Angular CLI:10.0.5节点：12.18.3操作系统：win32 x64
我该怎么解决这个问题？
我通过在Visual Studio Code终端中运行以下命令解决了这个问题。
node --max_old_space_size=8192 ./node_modules/@angular/cli/bin/ng build --prod
在ng build --prod的位置上，我使用了上述命令。
