Angular 2 AoT Heep 错误 [英] Angular 2 AoT Heep Errors

问题描述

AoT 编译导致JavaScript heap out of memory"错误

AoT compilation resulting in " JavaScript heap out of memory" error

我正在尝试按照 angular.io 上提供的 AoT 指南来编译我的项目

I am trying to compile my project by following the AoT guide available on angular.io

下面是我的 aot 类型脚本配置文件

Below is my typesccript configuration file for aot

<代码>{编译器选项":{emitDecoratorMetadata":真，"experimentalDecorators": 真,模块":es2015"，"moduleResolution": "节点",noImplicitAny":假，"suppressImplicitAnyIndexErrors": true,noEmitOnError":真，"removeComments": 真,源地图":假，"目标": "es5","outDir": "../content/app/"},角度编译器选项":{"genDir": "aot",skipMetadataEmit":真},排除": [节点模块"，"打字/主要",打字/main.d.ts"]}

我正在使用以下命令进行编译:

I am compiling using below command:

D:\MyProject\node_modules\.bin>ngc -p ../../app/tsconfig-aot.json

编译需要时间并最终出现以下错误:

It takes times in compilation and ends up with below errors:

推荐答案

如果您在尝试接受的答案后仍然在 Windows 上遇到此问题，您可以使用以下解决方法 (@angular/compiler-cli 2.2.1):

If you still have this issue on windows after trying the accepted answer you can use the following workaround (@angular/compiler-cli 2.2.1):

node --max-old-space-size=8192 node_modules/@angular/compiler-cli/src/main.js -p tsconfig-aot.json

这可能不适用于未来的更新，因为如果您解释 ./node_modules/.bin/ngc，上述所有内容都是指向实际的 js 文件.

This might not work with future updates as all the above does is point to the actual js file if you interpret ./node_modules/.bin/ngc.
