node.js - 构建 Angular 项目导致内存不足

问题描述

尝试在带有 -aot 标志的 Linux 服务器上构建 Angular 项目时，出现错误。我尝试将我的实例升级到更高的 CPU 内核、更多的 RAM 并打开 SWAP 分区，但错误仍然发生得更快。

这是尝试从终端以及带有我使用的标志的命令进行构建时。

ng build --target=production --environment=prod --aot

我尝试了这里提到的解决方案，https://www.npmjs.com/package/increase-memory-limit 但仍然没有运气

解决方案

对于产品构建，运行以下命令：

节点 --max_old_space_size=4096 node_modules/@angular/cli/bin/ng 构建 --target 生产

有关更多优化标志，请使用以下命令：

它具有内置的缓存破坏和其他好东西：

节点 --max_old_space_size=4096 node_modules/@angular/cli/bin/ng build --target production --build-optimizer --vendor-chunk
