And the ng versoin in my application shows :

@angular/cli: 1.3.2    
node: 6.11.2     
os: linux x64     
@angular/animations: error     
@angular/common: error     
@angular/compiler: error     
@angular/core: error     
@angular/forms: error     
@angular/http: error     
@angular/platform-browser: error     
@angular/platform-browser-dynamic: error     
@angular/platform-server: error     
@angular/router: error     
@angular/cli: error     
@angular/compiler-cli: error    

I tried to remove and reinstall angular/cli but it doesn't make any changes:

Answer 1

Try re-installing your CLI.

npm uninstall -g @angular/cli

npm cache clean

npm install -g @angular/cli@latest

Answer 2

Try this command:

npm install @angular/{animations,common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router}

Answer 3

delete node_modules from your project and run

npm install

this will work
