RVM而on Rails的

Question

安裝Ruby我一直on Rails的在Mac上從本網站安裝Ruby教程以下未發現：

http://ruby.railstutorial.org/

我安裝RVM，它不能正常工作。本教程說輸入以下命令：

~ $ [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" 

後，我這樣做，它似乎，它說這已成功加載：

~ DUFF$ rvm reload 
RVM reloaded! 
~ DUFF$ rvm notes 
Notes for Darwin (Mac OS X) 
For Lion, Rubies should be built using gcc rather than llvm-gcc. Since 
/usr/bin/gcc is now linked to /usr/bin/llvm-gcc-4.2, add the following to 
your shell's start-up file: export CC=gcc-4.2 
(The situation with LLVM and Ruby may improve. This is as of 07-23-2011.) 

For Snow Leopard be sure to have Xcode Tools Version 3.2.1 (1613) or later 
You should download the latest Xcode tools from developer.apple.com. 
    (This is since the dvd install for Snow Leopard contained bugs). 

If you intend on installing MacRuby you must install LLVM first. 
If you intend on installing JRuby you must install the JDK. 
If you intend on installing IronRuby you must install Mono (version 2.6 or greater is recommended). 

To seamlessly abandon the Apple-installed system ruby (ruby 1.8.7 patchlevel 174 for Snow Leopard): 

rvm install 1.8.7 # installs patch 302: closest supported version 
rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system # migrate your gems 
rvm --default 1.8.7 


NOTE: For all installations, as of 1.7, RVM no longer autoloads .rvmrc files. In order to  return this functionality, you MUST add 'export rvm_project_rvmrc=1' to your $HOME/.rvmrc file. This causes RVM to override 'cd' which, while toggleable even < 1.7, is currently defaulted to 'off'. This knob returns the previous behaviour to active which causes per-project .rvmrc files to be loaded once again. 

例如：echo '出口rvm_project_rvmrc = 1' >> $ HOME /.rvmrc & & RVM重裝

所以，畢竟我進入這個遵醫囑：

type rvm | head -n1 

，它說：

-bash: type: rvm: not found 

這樣長的介紹後，我的問題是你知道它爲什麼不承認RVM類型它似乎已經安裝之後。我是一個完整的新手，所以請溫柔。我一直在討論很多問題，直到現在這個問題似乎都很順利。

任何幫助，將不勝感激。謝謝。

Answer 1

您是否正在學習本教程？ http://beginrescueend.com/rvm/install/

您應該運行此命令全：

echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile 

這樣它添加到你的.bash_profile文件，並在每一個新的終端加載。您輸入的命令只會爲單個終端會話加載rvm函數。

.rvm/scripts/rvm是一個shell腳本，它將所有必要的函數加載到您的環境中。

看一看the same question I posted some time ago.

的安裝指南說，在終端「註冊」 RVM這樣：

user$ echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile 

基本上，當你在你的shell加載RVM功能，在那裏你」重新放置指令取決於你的分佈;這裏是進入.bash_profile。作爲Ubuntu的用戶，我發現使用.bashrc而不是.bash_profile效果更好。

.bash_profile和.bashrc之間的差額，這裏概述：http://www.joshstaiger.org/archives/2005/07/bash_profile_vs.html
