Can I install gems with apt-get on Ubuntu?
提问by Genadinik
I am new to Ruby and just diving in. The Ruby tutorial says I should get the packaging system from here: http://rubyforge.org/frs/?group_id=126
我是 Ruby 新手，刚开始学习。Ruby 教程说我应该从这里获取打包系统：http: //rubyforge.org/frs/?group_id=126
I am on Ubuntu Linux. The page has a .tar and a .gem option for downloading. Which should I download?
我在 Ubuntu Linux 上。该页面有一个 .tar 和一个 .gem 选项供下载。我应该下载哪个？
Also, are gems exactly analogous to Java jars? And why do I need the gem packaging system if I can just download gems one by one as they are needed?
另外，gems 是否与 Java jar 完全类似？如果我可以根据需要一一下载 gem，为什么还需要 gem 打包系统？
