I'm developing an Asp.Net Core 2 and Angular 5 project in visual studio 2017.

When I'm going to publish my project then the error 'The command "npm run build -- --prod" exited with code 1' show in error list window.
I created the project with Angular CLI in ASP.NET Core 2 Angular template link and everything was fine and the project run and publish correctly.
After a while, I don't know what exactly happens that cause the project doesn't publish.

In the npm-debug.log file

解决方案

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

.
