Problem:

Getting an error when running dotnet publish command.
“npm run build — –prod” error on Visual Studio 2017 .NET Core Angular Project.

Solution

Edit your .csproj file: Right click on you project – select Edit ____.csproj

Replace this:

<Exec WorkingDirectory="$(SpaRoot)" Command="npm run build -- --prod" />
<Exec WorkingDirectory="$(SpaRoot)" Command="npm run build:ssr -- --prod" Condition=" '$(BuildServerSideRenderer)' == 'true' " />

With this:

<Exec WorkingDirectory="$(SpaRoot)" Command="npm run build --prod" />
<Exec WorkingDirectory="$(SpaRoot)" Command="npm run build:ssr --prod" Condition=" '$(BuildServerSideRenderer)' == 'true' " />
