I am getting this error on save changes with --env.aot, if I remove --env.aot leaving tns run android --bundle --env.unglify --env.snapshot the cli is working perfectly fine on save changes

Step to reproduce:

1. tns create myApp --ng;cd myApp;npm i nativescript-dev-webpack --save-dev;npm install;tns platform add android;tns run android --bundle --env.unglify --env.snapshot --env.aot
2. save changes
3. after successfully synced application org.nativescript.myApp this error appears in CLI

Heya, this seems to be a duplicate of #566. The good news are that the fix is already on PR :)

[swetanshu84]

The only solution for this kind of issue is , just update your angular cli version as well as typescript version.
