Angular AOT编译器 – TypeError：this.compiler.analyzeModules

https://angular.io/guide/aot-compiler

我正在开发的项目是使用快速入门种子开发的,如下所述：

https://angular.io/guide/setup

该项目在没有使用AOT编译器的情况下工作正常,但是当我尝试按照说明使AOT编译器工作时,我收到以下错误(这是在Windows 8上)：

C:UserszzzzzDesktopquickstart>"node_modules/.bin/ngc" -p ./src

当我检查我安装的@ angular / compiler的版本时,我得到4.2.2,这似乎是最新的版本：

C:UserszzzzzDesktopquickstart>npm view @angular/compiler version
4.2.2

在Github上查看源代码,我看到在angular / packages / compiler / src / aot / compiler.ts中有一个名为analyzeModulesAsync的函数：

https://github.com/angular/angular/blob/master/packages/compiler/src/aot/compiler.ts

但是,当我在我的node_modules文件夹上为analyzeModulesAsync执行grep时,我只看到对该函数的调用.我没有看到它的定义.事实上,compiler.d.ts中的类定义似乎与Github上的compiler.ts文件有几点不同.

我已经尝试通过删除整个node_modules文件夹并重新运行npm install来“重新安装”,并且错误消息是相同的.

我确实在这里看到了一个类似的问题：Angular AOT failing at compilation (something with angular/compiler-cli),但是我对npm版本控制知之甚少,不知道可能出现什么问题,或者如何修复它.

关于我是否在某处篡改了某些指令,或者有更深层次的工作的任何想法？

解

问题在于package.json中@ angular / compiler-cli和@ angular / platform-server的版本不匹配.一旦我将它们更改为“~4.0.0”以匹配其余的角度模块,删除了node_modules文件夹并重新运行npm install,编译器就可以了.

我的工作理论是,因为我在两周前克隆了快速入门,并运行了这个命令：npm install @ angular / compiler-cli @ angular / platform-server – 昨天从教程中保存,这就是导致版本不匹配的原因.
