Failed to start node process

[joelnotified]

Sorry for the double post (left a question on stackoverflow)

I'm using Microsoft.AspNetCore.NodeServices 1.1.1 in my ASP.Net Core application. Everything has been working fine, but now I'm on a new computer and I get the following error:

System.InvalidOperationException:
Failed to start Node process. To resolve this:.

[1] Ensure that Node.js is installed and can be found in one of the PATH directories.
	Current PATH enviroment variable is: ....
	Make sure the Node executable is in one of those directories, or update your PATH.

[2] See the InnerException for further details of the cause.

I have removed the path variables from this question, but the directory where Node is installed is listed in there (C:\Program Files\nodejs\;).

node -v in a terminal gives me v6.11.0 so it is added to the path.

Nothing in the code has changed since it last worked, only my computer. Does anyone know what could be wrong?

Ok, so it was due to a missing folder on my new computer. Just a bit misleading error :)

This is how it was configured in Startup.cs:

services.AddNodeServices(options =>
{
    options.ProjectPath = "Path\That\Doesnt\Exist";
});

I added the path and now everything works as it should.

Maybe it's good idea to reopen that issue and add some assertion to NodeService that check if this path exists?

I am getting below error, Please help me on this. I am using React template using docker support for windows container. Although I have added both npm and nodejs folder path to Environmental folder.
