I'm trying to get contrib-gpio package installed on windows. I followed this guide for installing Node-Red, [https://nodered.org/docs/getting-started/windows](https://nodered.org/docs/getting-started/windows)  
I installed the build tools. It looks like contrib-gpio needs serialport, so I tried to install that first which seems to install but then after installing gpio, when starting Node-Red, the log shows: `13 Oct 10:02:15 - [warn] [node-red-contrib-gpio/gpio] Error: Could not locate the bindings file. Tried: → C:\Users\Matt\node_modules\@serialport\bindings\build\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\build\Debug\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\build\Release\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\out\Debug\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\Debug\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\out\Release\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\Release\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\build\default\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\compiled\10.16.3\win32\x64\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\addon-build\release\install-root\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\addon-build\debug\install-root\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\addon-build\default\install-root\bindings.node → C:\Users\Matt\node_modules\@serialport\bindings\lib\binding\node-v64-win32-x64\bindings.node`

Any quick fix before I quit and wait for my Pi to try again?

It seemed to install fine. I brought up my node red IDE page and the Serial Port Nodes were displayed!! Great! I wired up the serial nodes and my…
