Philippe's Expérience Note

參考了很多 Mac Ruby 更新的文章，大部分的人還是傾向直接用 MacPorts 更新，趁著更新的同時也記錄一下更新的筆記

首先如果你的 Mac 還沒裝 MacPorts 先到官網下載 MacPorts-1.9.2.pkg
安裝完後進行更新

$sudo port -d selfupdate 
MacPorts command:
port -d selfupdate #=> 升級 macport
port install xxx  #=> 安裝 xxx 軟體
port upgrade outdated #=> 升級所有軟體
port installed   #=> 列出已經安裝軟體
port search xxx  #=> 列出與 xxx 條件相符的軟體


接下來，安裝 ruby1.9
(註. 一般來說用 MacPorts 安裝 ruby 要指定版本，如果你只下 “port install ruby” 指令，那安裝之後的版本是 1.8.7…)

$sudo port install ruby1.9 

安裝之後的 path /opt/local/bin

ruby1.9 有幾個檔案需要更動連結
=> erb1.9
=> gem1.9
=> irb1.9
=> rake1.9
=> rdoc1.9
=> ri1.9
=> ruby1.9
=> testrb1.9 

移除 1.8 path /usr/bin

$sudo rm /usr/bin/erb
$sudo rm /usr/bin/gem
$sudo rm /usr/bin/irb
$sudo rm /usr/bin/rake
$sudo rm /usr/bin/rdoc
$sudo rm /usr/bin/ri
$sudo rm /usr/bin/ruby
$sudo rm /usr/bin/testrb

將 link 更新為 1.9

$sudo ln -s /opt/local/bin/erb1.9 /usr/bin/erb
$sudo ln -s /opt/local/bin/gem1.9 /usr/bin/gem
$sudo ln -s /opt/local/bin/irb1.9 /usr/bin/irb
$sudo ln -s /opt/local/bin/rake1.9 /usr/bin/rake
$sudo ln -s /opt/local/bin/rdoc1.9 /usr/bin/rdoc
$sudo ln -s /opt/local/bin/ri1.9 /usr/bin/ri
$sudo ln -s /opt/local/bin/ruby1.9 /usr/bin/ruby
$sudo ln -s /opt/local/bin/testrb1.9 /usr/bin/testrb

下一步，如果你已經在舊版的 gem 裝很了很 library 請先備份清單

$sudo gem list

將顯示的清單貼到文字編輯器中就行了
在 gem1.9 重新安裝之前的清單即可
Rails 的部份也可用 gem1.9 重新安裝


$sudo gem1.9 rails
