$ sudo curl http://npmjs.org/install.sh | sh
$ wget https://github.com/downloads/github/hubot/hubot-1.0.0.tar.gz
$ tar zxvf hubot-1.0.0.tar.gz
$ cd hubot
$ npm install
$ ./bin/hubot
Mine had some path issues that showed up as
env: coffee: No such file or directory
but manually setting the path to the .bin directory in hubot's generated node_modules seemed to do the trick.
