Recently I was trying to build a complex project which included also node js code and was deployable to IIS. The error I faced on visual studio during the build was the below.
"npm run build" exited with code 1 - Visual Studio "npm install" exited with code 1 - Visual Studio
both of which were misleading.
In order to locate the error I navigated on the Node project and tried to build using
npm run build
Command line never lies. I was able to determine that webpack was not installed.
In order to resolve I executed:
npm install -g webpack npm install -g webpack-cli
