Error installing - 'linux/types.h' file not found

[judholliday]

node-gyp is throwing an error during installation. Tried a few things like making sure node was up to date, etc, but to no avail. Any help would be appreciated.

> node-gyp rebuild

Try:

sudo apt-get install build-essential

Turns out the problem was between they keyboard and the chair. Wrong ssh window means I was trying to install on my mac instead of my pi. Clearly time to call it a night. :)

So how does one install on Mac OSX? I get the same error on Mountain Lion. Is Mac OSX supported?

It's currently made for embedded systems that have direct access to the i2c bus.

@ghendricks you can make it an optional dependency for your OS X app using the optionalDependencies section of your package.json and then checking for a valid require by doing the following:

var i2c;
try {
    i2c = require('i2c');
} catch { // handle no-i2c case }

Then you can stub out methods to handle the no i2c case and still test/develop/debug your application from a non-embedded system.

Do you think it could be ported to also support OSX ?
