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:

   Tools > Options > Projects and Solutions > Web Package Management > External Web Tools

If NodeJS and npm aren't installed on your environment path Add NodeJS and npm folder to the top of the list else move $(path) to the top of the list
