I have put [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.at the bottom of the .bashrc_profile.
我已经放在.bashrc_profile[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.的底部。
When I open the new Terminal window, I have done rvm defaultevery time to reset from system ruby to rvm installed ruby.
当我打开新的终端窗口时，我rvm default每次都从系统 ruby 重置为 rvm 安装的 ruby。

If RVM isworking in the shell but just isn't using the preferred ruby as default, set it with the following for 1.9.3:
如果RVM正在工作的外壳，但只是没有使用首选红宝石作为默认情况下，以下为1.9.3设置：
rvm --default use 1.9.3
If RVM isn'tworking, it's likely a login shell problem that RVM isn't loading:
如果 RVM不工作，则可能是 RVM 未加载的登录 shell 问题：
Login shells (typically when a terminal window is opened in an X window manager) will use .bash_profilebut interactive, non-login shells reference .bashrc(likely where the rvm shell code are loaded).
登录 shell（通常在 X 窗口管理器中打开终端窗口时）将使用.bash_profile但交互式的非登录 shell 引用.bashrc（可能是加载 rvm shell 代码的位置）。

Cheap fix, symlink them:
便宜的修复，符号链接它们：
ln -s ~/.bashrc ~/.bash_profile
ln -s ~/.bashrc ~/.bash_profile
Option 2
选项 2
Optionally, some terminals (e.g. gnome-terminal) offer settings to force login shells for each new terminal session too.
或者，某些终端（例如 gnome-terminal）也提供设置以强制每个新终端会话的登录 shell。
Option 3
选项 3
Create a .bash_loginfile with the following contents:
创建一个.bash_login包含以下内容的文件：
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
(Bash will check for ~/.bash_profile, then ~/.bash_login, and finally ~/.profile.)
（Bash 将检查~/.bash_profile，然后~/.bash_login，最后~/.profile。）
See the bash man pagefor additional detailed information.
有关其他详细信息，请参阅bash 手册页。

I'm not familiar with a .bashrc_profilefile. I think you mean to have this line in your .profileor .bashrcfile.
我对.bashrc_profile文件不熟悉。我认为您的意思是在您的.profile或.bashrc文件中包含这一行。

There are to things to check:
有一些事情要检查：
go to terminal emulator, preferences, and enable login shell, sometimes it is required to use
/bin/bash --logininstead of just switching, put/bin/loginwould not work,one of
~/.bash*files might be resettingPATH, comment out anyPATH=...lines.
转到终端模拟器，首选项，并启用登录shell，有时需要使用
/bin/bash --login而不仅仅是切换，放置/bin/login不起作用，其中一个
~/.bash*文件可能正在重置PATH，注释掉任何PATH=...行。
After it is done make sure to open a new terminal (make sure to close it before).
完成后确保打开一个新终端（确保之前关闭它）。

Use this $ source $(rvm 1.9.3 do rvm env --path)and specify the version you want to use everytime you open a terminal. After you put that in you don't need to open another one because it will default back. So if you want to use v. 2.2.1 $ source $(rvm 2.2.1 do rvm env --path)
使用它$ source $(rvm 1.9.3 do rvm env --path)并指定每次打开终端时要使用的版本。在你把它放进去之后，你不需要再打开一个，因为它会默认回来。所以如果你想使用 v. 2.2.1$ source $(rvm 2.2.1 do rvm env --path)
