Perform any of the following options as long as there is an error

1. For passing an argument to build command:

   change ‘npm run build — –prod’ to ‘npm run build –prod’ in the .csproj file

2. Open ClientApp folder and Update project angular-cli with this CMD command:

   npm install –save-dev @angular/cli@latest

3. Update visual studio NodeJS and npm from:
