Angular 2 - 使用 AOT 构建：Javascript 堆内存不足

Question

我正在开发一个 angular2 项目。我运行下面的命令来构建 AOT 包。

ng build --aot --prod

但它返回错误：

 68% building modules 1135/1172 modules 37 active ...cy/node_modules/rxjs/operator/last.js

我搜索了解决方案，在failed - JavaScript heap out of memory”和Angular 2 AOT build error - JavaScript heap out of memory发现了两个类似的问题。

在这些帖子之后，添加add --max-old-space-size=9000 属性，但结果发生了变化：

69% building modules 1689/1690 modules 1 active .../@firebase/database/dist/index.cjs.js

#
# Fatal error in , line 0
# API fatal error handler returned after process out of memory
#
#
#
#FailureMessage Object: 0x7f6efe578980Illegal instruction (core dumped)

项目不是很大，前几天搭建成功。并且 ng build 没有 --aot --prod 有效。

Answer 1

这对我有用

node --max_old_space_size=5120 ./node_modules/@angular/cli/bin/ng build --prod --build-optimizer

Answer 2

通过将 typecript 表单 2.6.x 更新到 2.7.x 问题已得到修复。
