A little issue I ran across. Maybe it'll help others. Fix is at the bottom.
After a clean Ubuntu 12.04 64bit server install, I got everything to install and build correctly by following the recipe posted on github
https://github.com/NarrativeScience/Log.io/wiki/v0.2.7-Build-Recipe-(Ubuntu-12.04) .
Trying to start up the harvester for the first time I get this:
Starting Log.io harvester...
Launching forever process...
info: Forever processing file: /usr/local/bin/log.io-harvester
monitor.send(JSON.stringify(options));
^
TypeError: Object #<ChildProcess> has no method 'send'
Done.
Done.
--------------------
I noticed forever is installed at version 0.10.0.
The fix is to install it again at 0.9.0 with the command "sudo npm install for...@0.9.0 -g".
After that, everything worked flawlessly. I hope this helps others.
