I2C does not work in the latest node version

[jscaglia]

Hi, I tried to install de node module to mi nodejs app but I can't. I suppose that the reason is my nodejs and NPM version.
Do you know if the library is not compatible with the last version of nodeJS? If this is the case, do you know how I could install it?

Regards.

I have tried the following and it worked for me (somehow):

1. npm list -g | head -1 which gives you your global npm directory
   (in my case /home/pi/.nvm/versions/node/v8.0.0/lib)
2. Change your working dir to this directory (cd ...)
3. Try a regular npm install i2c which will install i2c and it's dependencies in the subfolder node_modules
4. In my case i was able to install the package depending on i2c without sudo and it worked.

Unfortunately it didn't work for me. My global npm directory is '/usr/local/lib' and when I tried install with and without sudo print this.
