When I hit ng serve on cmd it's not working although its working 1st & 2nd time but its not working now. All things are running perfectly. eg ng --version .. the problem is only with ng serve ..it only runs for the 1st & 2nd time..

Answer 1

try update your angular-cli global:

npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli@latest

Then exclude the node_modules folder.

Change the angular-cli dev dependency version of your package.json , according with the ng --version :

Finally run npm install and after run ng serve --open .

Answer 2

First check your folder structure.. In angular-cli 0.0.30 there's a client folder between src/ and app. So now, when you generate a project, it's src/client/app not src/app. So, if you're upgrading the CLI for an existing project, please add that folder manually and move app inside of the new client dir.

If you dont want to uninstall your angular compiler. just go to the project and do the following: npm install npm cache clean npm audit fix

It should work fine.
