Node-red-contrib-modbus needs visual studio to install !?

General

Hello,
I am trying to install node-red-contrib on wnidows 10. I have a really weird error : It says that I have to install VS ??? Is this for real ? Anyone knows why ?? I'm on a student computer, if I could avoid it it would be great.

Actually, it seems to be needed to access to the serial ports ? This topic has the same issue :
https://discourse.nodered.org/t/unable-to-install-node-red-node-arduino/

If there is a way to install the contrib without VS, I'd enjoy knowing it.

There is not - however, you dont need the full VS install - just build tools as explained in that post.

From an elevated command prompt...

npm install --global windows-build-tools

... Then try installing the modbus node again.

In simple terms, the serial port binary/bindings must be built on your machine at installation time.

You can always uninstall it afterwards (but other nodes that have a compilation step will then fail)
