Angular AOT failing at compilation (something with angular/compiler-cli)

问题

After going through the AOT tutorial on the Docs page, I am trying to compile angular 2 AOT and am getting the following error

"node_modules/.bin/ngc" -p tsconfig-aot.json

TypeError: compiler.AnimationParser is not a constructor
at Function.CodeGenerator.create (C:\Projects\NeilKellyClient4\node_modules\@angular\compiler-cli\src\codegen.js:108:400)

Compilation failed

I am getting stuck at this point. Any reason why angular/compiler-cli is throwing this error ?

回答1:

As you say, it appears to be a version conflict. I had the same issue, and had to reinstall the package to get it to work, with the version specified. I would suggest installing the release versions and re-running until you get what you wanted. For what it's worth, I had same error, and 2.1.2 worked for me.

npm install @angular/compiler-cli@2.1.2 --save-dev

As to why, I would speculate the package versions are out of sync. Try running npm list --depth=0 and see if anything pops up. Might give a hint as to what's out of whack.

回答2:

The way I got rid of it was using 2.2.0 for all the angular packages including compiler-cli. Then did npm install again to reload all package dependencies as per 2.2.0 and it worked. Here is a part of package.json:

"dependencies": {
    "@angular/common": "~2.2.0",
    "@angular/compiler": "~2.2.0",
    "@angular/compiler-cli": "^2.2.0",
    "@angular/core": "~2.2.0",
    "@angular/forms": "~2.2.0",
    "@angular/http": "~2.2.0",
    "@angular/platform-browser": "~2.2.0",
    "@angular/platform-browser-dynamic": "~2.2.0",
    "@angular/platform-server": "^2.2.0",
    "@angular/router": "~3.2.0",
    "@angular/upgrade": "~2.2.0",
