FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

今天在用angular 7的build prud的时候出现了下面的错误：

 1: node::Abort() [ng build --prod --build-optimizer --base-href /admin --deploy-url /admin/]

heap out of memory

解决方法

在你的命令前面加上：

node --max_old_space_size=8192 ./node_modules/@angular/cli/bin/ng

就可以了，这是为了提升node的内存上限。
