MAC環境下配置Ruby環境
步驟1 - 安裝 RVM
RVM 是幹什麼的這裡就不解釋了,後面你將會慢慢搞明白。
開啟終端輸入$ curl -L https://get.rvm.io | bash -s stable
期間可能會問你sudo管理員密碼,這裡可能需要等待一段時間後就可以成功安裝好 RVM。
案例資訊如下:
lihuifengdeMacBook-Pro:~ lihuifeng$ curl -L https://get.rvm.io | bash -s stable

but no GPG software exists to validate it, skipping.
Upgrading the RVM installation in /Users/lihuifeng/.rvm/
RVM PATH line found in /Users/lihuifeng/.profile /Users/lihuifeng/.bashrc /Users/lihuifeng/.zshrc.
RVM sourcing line found in /Users/lihuifeng/.bash_profile /Users/lihuifeng/.zlogin.
Upgrade of RVM in /Users/lihuifeng/.rvm/ is complete.
# lihuifeng,
#
# Thank you for using RVM!
# We sincerely hope that RVM helps to make your life easier and more enjoyable!!!
#
# ~Wayne, Michal & team.

Upgrade Notes:
* No new notes to display.
--這裡就表示已經成功安裝了--
然後,載入 RVM 環境
$ source ~/.rvm/scripts/rvm
檢查一下是否安裝正確 :輸入命令 rvm -v ,如果正確會列出RVM版本 如下所示:
$ rvm -v A RVM version 1.26.10 (latest) is installed yet 1.25.28 (stable) is loaded. Please do one of the following: * 'rvm reload' * open a new shell * 'echo rvm_auto_reload_flag=1 >> ~/.rvmrc' # for auto reload with msg. * 'echo rvm_auto_reload_flag=2 >> ~/.rvmrc' # for silent auto reload.
步驟2 - 用 RVM 安裝 Ruby 環境
輸入命令 $ rvm install 2.0.0
$ rvm install 2.0.0
同樣繼續等待漫長的下載,編譯過程,完成以後就安裝好了。
A RVM version 1.26.10 (latest) is installed yet 1.25.28 (stable) is loaded.
Please do one of the following:
* 'rvm reload'
* open a new shell
* 'echo rvm_auto_reload_flag=1 >> ~/.rvmrc' # for auto reload with msg.
* 'echo rvm_auto_reload_flag=2 >> ~/.rvmrc' # for silent auto reload.
步驟3 - 設定 Ruby 版本
RVM 裝好以後,需要執行下面的命令將指定版本的 Ruby 設定為系統預設版本
$ rvm 2.0.0 --default
同樣,也可以用其他版本號,前提是你有用 rvm install 安裝過那個版本
測試是否正確
lihuifengdeMacBook-Pro:~ lihuifeng$ ruby -v ruby 2.0.0p481 (2014-05-08 revision 45883) [x86_64-darwin13.1.0] lihuifengdeMacBook-Pro:~ lihuifeng$ gem -v 2.2.2 這有可能是因為Ruby的預設源使用的是cocoapods.org,國內訪問這個網址有時候會有問題,網上的一種解決方案是將遠替換成淘寶的,替換方式如下: $gem source -r https://rubygems.org/ $gem source -a https://ruby.taobao.org lihuifengdeMacBook-Pro:~ lihuifeng$ gem source -r https://rubygems.org/ https://rubygems.org/ removed from sources lihuifengdeMacBook-Pro:~ lihuifeng$ gem source -a https://ruby.taobao.org https://ruby.taobao.org added to sources
要想驗證是否替換成功了,可以執行:
$ gem sources -l
正常的輸出結果:
lihuifengdeMacBook-Pro:~ lihuifeng$ gem sources -l*** CURRENT SOURCES ***
https://ruby.taobao.org
這裡就表示已經把Ruby環境成功的安裝到了Mac 上了。
用RVM升級Ruby
- #檢視當前ruby版本
- $ ruby -v
- ruby 1.8.7
- #列出已知的ruby版本
- $ rvm list known
- #安裝ruby 2.3
- $ rvm install 2.3
