七周七语言---准备篇ruby

想快速学习下各种语言，正好看到了一本《七周七语言》，随便翻了一下，感觉很满足好奇心的一本书，决定趁着时间还充裕，学习一下。

ruby的提供很多方法，这里根据《programming ruby》中使用rvm安装ruby1.9.3

登录到https://rvm.io/，可以看到安装rvm的方法，这里使用（需要git支持，sudo apt-get install git curl）

curl -L get.rvm.io | bash -s stable

将rvm添加到shell上，

source ~/.rvm/scripts/rvm

安装ruby

rvm install ruby-1.9.3-p362

然后就是安装过程了

lambertchow@lambertchow:~$ rvm install ruby-1.9.3-p362

安装成功。

 

之间自己编译国，没解决本地问题，放弃了。有简单的方法，还是别折腾的最好。

呵呵，ruby作者都说了

This is probably more work than you were expecting. If all you wanted to do was install a
prepacked Ruby, we’d agree. But what you’ve really done here is given yourself an incredible
amount of flexibility. Maybe in the future a project comes along that requires that you use Ruby
1.8.7. That’s not a problem—just use rvm install 1.8.7 to install it, and use rvm use 1.8.7 to
switch to it.
