列出ruby版本

console:~$ rvm list

rvm rubies

ruby-2.0.0-p481 [ i686 ]

# => - current
# =* - current && default
#  * - default

尝试使用特定版本的ruby

console:~$ rvm use 2.0.0

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.

     Usually this is caused by shell initialization files. Search for PATH=... entries.
     You can also re-add RVM to your profile by running: rvm get stable --auto-dotfiles
     To fix it temporarily in this shell session run: rvm use ruby-2.6.5
     To ignore this error add "rvm_silence_path_mismatch_check_flag=1" to your "~/.rvmrc" file.

其他回答

我的环境是OSX优胜美地。有同样的问题....通过添加以下内容来解决

1)编辑并添加以下一行到.bash_profile文件。

[[-s "$HOME/。Rvm /scripts/ Rvm "]] &&。“$ HOME / .rvm /脚本/区”

2)重启终端,重试RVM命令

输入bash——从终端登录。然后给rvm使用2.0.0

您需要添加源~/。Rvm /scripts/ Rvm到~/。your_shellrc文件。从现在开始,当你加载一个shell时,rvm将被加载。

例如:

如果你使用的是ZSH shell,需要添加~/。zshrc中

如果您使用bash shell,需要添加~/。bashrc文件(

然后打开一个新标签,看看效果。

如果RVM安装了专用的ubuntu RVM安装程序https://github.com/rvm/ubuntu_rvm, RVM脚本的路径将不同于/usr/share/rvm/scripts/rvm.因此,要将它添加到你的.bashrc中,运行以下命令:

echo 'source "/usr/share/rvm/scripts/rvm"' >> ~/.bashrc

如果你不想每次打开一个终端都这样,再做一遍上面的建议,只需添加

source ~/.rvm/scripts/rvm

在~/.bashrc的末尾
