Upgrade of Angular version 5-CodePudding

I am trying to upgrade my Angular version from 5 to 6 using the commands shown here, but it doesn't seem to be working:

npx @angular/cli@6 update @angular/cli@6
npx @angular/cli@6 update @angular/core@6

Kindly help me to resolve this issue.

Couple options, either update your package.json with the specific version you want to use and run npm install to install that latest version or run

npm install -g @angular/cli@6  //globally
npm install --save-dev @angular/cli@6  
ng update @angular/core@6
