hey i just installed and following your instruction in readme, but still have a lot error, for example image

saeful1998 commented 5 years ago

is this work on node-red v 0.20.7 ?

johnty commented 5 years ago

According to the readme, IIRC the dependency i2c is no longer supported and needs to be manually compiled.

It should work with node v8.x; node-red version probably doesn’t matter unless it requires you to move up to node v10.x as well.

Sorry,but i dont know how to compile manuall and how fix that issues?

johnty commented 5 years ago

I made these instructions for someone a while ago, you can try and see if it works. note you need to have node v8.x instead of the latest for things to compile!

go to your node-red node_modules folder:

cd ~/.node-red/node_modules

Delete the old version (if it exists due to a previous automated install. if its not installed there then it won't find it):

rm -rf node-red-contrib-i2clcd

Clone the repo:

git clone https://github.com/johnty/node-red-contrib-i2clcd

now you should have the folder at

~/.node-red/node_modules/node-red-contrib-i2clcd

now go into the folder, and do an npm install:

cd node-red-contrib-i2clcd
npm i

this version should install fine with the correct dependency.

go back to your node-red home, and run node-red:

cd ~/.node-red
node-red
