ASP.NET Core not finding npm - asp.net

Question

I have a new Asp.NET Core Web / React application.
When I try to run it I get the error:
An unhandled exception occurred while processing the request.
AggregateException: One or more errors occurred. (One or more errors
occurred. (Failed to start 'npm'. To resolve this:.
[1] Ensure that 'npm' is installed and can be found in one of the PATH
directories.
I have a PATH variable set up:
C:\Program Files\nodejs
In this folder is node.exe
Do I need to install something into the project?
I have made no other changes to the project since creating it from the VS Web Application template. I just want it to run...
The full path error list:
