From: Ruby Newbee Date: 2010-01-27T21:20:50+09:00 Subject: being confused about libraries Hello, When running gem I always need to add this lib and that lib (I'm using an ubuntu desktop linux). For example, for sqlite3, sometime I installed it: gem install sqlite3-ruby While some other time I installed it: apt-get install sqlite3 So what's the relation between the system "sqlite3" and (most likely) ruby's "sqlite3-ruby"? Thanks. Jenn.
