Hello, I'm using angular cli and I updated my app to angular4 using "npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router,animations}@latest typescript@latest --save " **

Versions.

Angular version: 2.0.X Browser:Chrome Language:TypeScript Node (for AoT issues): node --version = 6.10.1

Repro steps.

when I run my app after updation I'm getting the following problem. I run my app using npm start and ng serve both.

The log given by the failure.

Module build failed: TypeError: Cannot read property 'exclude' of undefined

Desired functionality.

simply it have to compile but error occur during compilation.

Mention any other details that might be useful.

Experiencing the same issue on windows.

Trying to update to Angular 4.

It was compiling fine on angular2 until I added

npm install @angular/common@latest @angular/compiler@latest @angular/compiler-cli@latest @angular/core@latest @angular/forms@latest @angular/http@latest @angular/platform-browser@latest @angular/platform-browser-dynamic@latest @angular/platform-server@latest @angular/router@latest @angular/animations@latest typescript@latest --save

Exact same error

Hi newnewb, Few days ago I was facing the issue but when I downgrade my project from angular 4.0.1 to 4.0.0 now my app is working properly. delete your node module and downgrade the angular dependency in 4.0.0 same as image and then run npm install.. hope it will work for you...

Hi @saurabhschauhan ,

I think as I read it was a typescript issue, anything below 2.1.x will lead to that error,

deleted my node modules, and updated the typescript version and angular version in my packages

"@angular/common": "^4.0.2",
"@angular/compiler": "^4.0.2",
"@angular/compiler-cli": "^4.0.2",
"@angular/core": "^4.0.2",
"@angular/forms": "^4.0.2",
"@angular/http": "^4.0.2",
"@angular/platform-browser": "^4.0.2",
"@angular/platform-browser-dynamic": "^4.0.2",
"@angular/platform-server": "^4.0.2",
"@angular/router": "^4.0.2",

"typescript": "^2.2.2",

this solved the issue for me

Heya, I don't think the issue you are experiencing is related to Angular CLI. I see references to awesome-typescript-loader in your error logs, you should open an issue in that repo instead.
