I am using MCP23017 but had t do a lot to get it working.
The best way to get it working is that you have to be in the directory node-red is installed on,
My directory is /hom/pi/.node-red
npm install i2c-bus@5.1.0
├─┬ i2c-bus@5.1.0
│ ├── bindings@1.5.0 deduped
│ └── nan@2.14.0 deduped (git+https://github.com/nodejs/nan.git#60e86a9d4c4536fbbd2a76814470edd66b23114e)
├── nan@2.14.0 (git+https://github.com/nodejs/nan.git#60e86a9d4c4536fbbd2a76814470edd66b23114e)
You can see I also loaded the latest version of nan@2.14.0 to fix some warnings.
Also install ncd-red-comm@1.6.9 because they all link to it.
This installs all the NCD nodes
npm i $(npm search --parseable ncd-red | cut -f 1)
Once all the packages are installed remember to run npm dedupe and npm rebuild
Once that's done you reboot the system so node-red pulls in the local node_modules files and it should show up in the admin console.
I can help if you get stuck.
