问题
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
0 info it worked if it ends with ok

15 error enoent This is most likely not a problem with npm itself
15 error enoent and is related to npm not being able to find a file.

回答1:
Perform any of the following options as long as there is an error
For passing an argument to build command:
change 'npm run build -- --prod' to 'npm run build --prod' in the .csproj file
Open ClientApp folder and Update project angular-cli with this CMD command:
npm install --save-dev @angular/cli@latest
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
.

Got same error, my environment:
.NET Core 2.1 RC-1
Angular v5.2.4
NPM v5.7.1
Node v8.11.2
And nothing mentioned above did not helped. Simple go to ".\ClientApp" //Angula-CLI project and run
npm run build
then you will see real errors - so that means simple you have some errors in code, so fix angular UI code and it will build fine :).

Maybe in command line NodeJS version of Visual Studio is old. In your command output we can see:
node@v6.10.3
Update NodeJS
回答4:
Try running: ng build "prod" and see what the actual error is.
回答5:
Check this maybe you have problem with lack of memory
"build": "node --max-old-space-size=4069 node_modules/@angular/cli/bin/ng build --prod",
