I am on VS 2017 and .NET Core 2 on Win 7. Tried creating a fresh app in .NET Core 2.0 and Angular using these instructions.
Running latest versions of node and npm :
node -v > v10.1.0
npm -v > v6.0.1
According to the instructions, I went ahead to build the application and got
Can't find Python
I checked env variables the path has python. Not sure why it can't find it.
The build seems to have "half worked" and got some dependencies sorted. The second go around building the app gave me a JavaScript Runtime Error .. which I think is due to crappy first build job.
I also tried running "npm install" in the ClientApp folder and gave the same errors, Can't find python.
Any help would be appreciated !

NET Framework 2.0 has been around for a decade but will be completely unsupported by Microsoft; the announced end of the extended support period is April 12, 2016. In lock-step with the . NET Framework, the corresponding version of Microsoft's development tool, Visual Studio 2005, is also at its end-of-life.
NET Core 2.1 is no longer supported and updates will no longer be provided. If your application uses NET Core 2.1, we strongly recommend you migrate your application to a supported version – . NET 3.1 or later. You can download these versions from the .
NET framework is highly outdated. Of course, the main reason behind this is the lack of cross-platform development, which was rectified in future versions released by Microsoft. Most developers and programmers prefer programming languages and frameworks that offer flexibility when working with them.
node-gyp has dependency on Python2.x. Install Python in your system.
