Trying to keep packages synced between two different computers can be a pain, and the robust Sublime Text 2 doesn’t have anything built in to make this easier. I’d commonly install a package at night at home, then be tripped up at work on my computer there when the package wouldn’t be installed.
Syncing packages & other settings is really easy with Dropbox, and it’s just a few quick steps in Terminal.
Go to the Sublime Text 2 application support directory.
$ cd ~/Library/Application\ Support/Sublime\ Text\ 2/
Create a symbolic link to the Packages directory in your Dropbox. Feel free to create it in a subdirectory of you Dropbox.
$ ln -s ~/Dropbox Packages
Now any Sublime will stay synced on any computer linked with your Dropbox account.
