RVM is not a function, selecting rubies with 'rvm use ...' will not work.
You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.

Your console is not running as a login shell and hence have no access to rvm function. If you are running Ubuntu, you can:
您的控制台未作为登录 shell 运行，因此无法访问 rvm 功能。如果您正在运行 Ubuntu，您可以：
- Open console
- Select Edit -> Profile Preferences
- Select tab: Title and Command
- Check box 'Run command as a login shell'
- Restart terminal
- 打开控制台
- 选择编辑 -> 配置文件首选项
- 选择选项卡：标题和命令
- 复选框“将命令作为登录 shell 运行”
- 重启终端

It seems like your rvm does not load ".bash_profile" properly. I have done to fix it in MAC OS X or Ubuntu 14.04 by opening terminal and write:
您的 rvm 似乎没有正确加载“.bash_profile”。我已经通过打开终端并写入在 MAC OS X 或 Ubuntu 14.04 中修复它：
source ~/.rvm/scripts/rvm

If you don't want that every time you open a terminal, do the suggestion above again, just add

at the end of ~/.bashrc
在......的最后 ~/.bashrc

The error is due to rvm is not running as in login shell. Hence try the below command:
该错误是由于 rvm 没有像在登录 shell 中那样运行。因此尝试以下命令：
/bin/bash --login
You will able run rvm commands instantly as login shell in terminal.
您将能够在终端中作为登录 shell 立即运行 rvm 命令。
Thanks!
谢谢！

Same principle as other answers, just thought it was quicker than re-opening terminals :)
与其他答案相同的原则，只是认为它比重新打开终端更快:)
bash -l -c "rvm use 2.0.0"
回答by Siva Praveen
You need to add source ~/.rvm/scripts/rvmto ~/.your_shellrc file. From now when you load a shell, rvm will be loaded.
您需要添加source ~/.rvm/scripts/rvm到~/.your_shellrc file. 从现在开始，当您加载 shell 时，将加载 rvm。
For example:
例如：
if you are using zsh shell, need to add in ~/.zshrcfile
如果您使用的是 zsh shell，则需要在~/.zshrc文件中添加
if you are using bash shell, need to add in ~/.bashrcfile
如果您使用的是 bash shell，则需要在~/.bashrc文件中添加
And then open a new tab to see the effect.
然后打开一个新标签查看效果。
