问题描述

我试图寻找一个小时左右的答案，但没有运气。我已经在我的rvm上安装了 ruby-2.0.0 ，但系统只检测到旧的 ruby-1.9.3 ！我将 / usr / bin / ruby 中的sym链接改为指向我的〜/ .rvm ruby，现在我当我运行 ruby -v

时，得到以下内容：

  ruby 2.0.0p451 （2014-02-24修订版45167）[x86_64-linux]

但是，当我尝试启动 rails server 我得到的错误说我目前的ruby版本是 1.9.3 我跑了 gem env 并且得到了一个令人惊讶的结果：

pre $ RubyGems环境： - RUBYGEMS VERSION： 1.8.23 - RUBY VERSION：1.9.3（2012-04-20 patchlevel 194）[x86_64-linux] - 安装目录：/var/lib/gems/1.9.1 - RUBY EXECUTABLE：/usr/bin/ruby1.9.1 - 可执行目录：/ usr / local / bin - RUBYGEMS平台： - ruby - x86_64-linux - 创业板路径： - /var/lib/gems/1.9.1 - /home/username/.gem/ruby/1.9.1 - 创业板配置： - ：update_sources => true - ：verbose => true - ：benchmark => false - ：backtrace => false - ：bulk_threshold => 1000 - install=> --no-rdoc --no-ri - update=> --no-rdoc --no-ri - 远程来源： - http://rubygems.org/

您可以看到它指向错误的位置。我试着修改 .gemrc 来让它起作用，但它仍然拒绝改变它的ruby安装目录。我不知道如何解决它。我尝试删除它们，并开始新鲜但显然它们不是通过 apt-get 安装的，所以我不知道如何删除它们！

任何帮助将非常感谢。

解决方案

第一个列表在RVM中的ruby版本

  rvm list

p>

  ruby-1.9.3-p484 [x86_64] 
 = * ruby-2.1.0 [x86_64] 
 
＃=> - 当前
＃= *  - 当前&&默认
＃*  - 默认

要使用像

  rvm使用ruby-2.1.0

你可以像这样设置默认的ruby

  rvm use --default ruby-2.1.0

现在检查您的ruby版本

  ruby -v

为了确保非交互式shell能够访问RVM， h2> 
 
 编辑 .bashrc 使用此命令
  sudo gedit /home/$USER/.bashrc 
  
确保您拥有这些在那里。 
  PATH = $ PATH：$ HOME / .rvm / bin＃将RVM添加到PATH以编写脚本
 [[-s/home/`whoami`/.rvm/scripts/rvm]]&& source/home/`whoami`/.rvm/scripts/rvm
  
现在编辑您的.bash_profile使用此命令
  sudo gedit /home/$USER/.bash_profile 
  
确保你有这些行。如果不添加它。
  if [-f$ HOME / .bashrc];然后
源$ HOME / .bashrc 
 fi 
  
重新启动您的终端。 / p> 
I tried looking for an answer for about an hour but no luck. I have installed ruby-2.0.0 with my rvm but the system only detects the old ruby-1.9.3 !I changed the sym link in /usr/bin/ruby to point to my ~/.rvm ruby and now I get the following when I run ruby -v
ruby 2.0.0p451 (2014-02-24 revision 45167) [x86_64-linux]
However when I try to start a rails server I get the error which says my current ruby version is 1.9.3 I ran gem env and got a surprising results:
RubyGems Environment:
  - RUBYGEMS VERSION: 1.8.23
  - RUBY VERSION: 1.9.3 (2012-04-20 patchlevel 194) [x86_64-linux]
  - INSTALLATION DIRECTORY: /var/lib/gems/1.9.1
  - RUBY EXECUTABLE: /usr/bin/ruby1.9.1
  - EXECUTABLE DIRECTORY: /usr/local/bin
  - RUBYGEMS PLATFORMS:
    - ruby
    - x86_64-linux
  - GEM PATHS:
     - /var/lib/gems/1.9.1
     - /home/username/.gem/ruby/1.9.1
  - GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :benchmark => false
     - :backtrace => false
     - :bulk_threshold => 1000
     - "install" => "--no-rdoc --no-ri"
     - "update" => "--no-rdoc --no-ri"
  - REMOTE SOURCES:
     - http://rubygems.org/
As you can see it is pointing to the wrong location. I tried modifying .gemrc to get it to work but it still refuses to change it's ruby installation directory. I have no idea how to fix it. I tried removing them all and starting fresh but apparently they are not installed via apt-get so I don't know how to remove them! 
Any help will be very much appreciated.Just for further info:
$ gem -v
1.8.23
 解决方案 
First list ruby versions in RVM
rvm list
For example mine says
   ruby-1.9.3-p484 [ x86_64 ]
=* ruby-2.1.0 [ x86_64 ]

# => - current
# =* - current && default
#  * - default
To use a ruby version use command like
rvm use ruby-2.1.0
You can set default ruby like this
rvm use --default ruby-2.1.0
Now check your ruby version
ruby -v
To ensure that non-interactive shells have access to RVM
Edit .bashrc using this command
sudo gedit /home/$USER/.bashrc
Make sure you have these lines there. If not add it.
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
[[ -s "/home/`whoami`/.rvm/scripts/rvm" ]] && source "/home/`whoami`/.rvm/scripts/rvm"
Now edit your .bash_profile using this command
sudo gedit /home/$USER/.bash_profile
Make sure you have these lines there. If not add it.
if [ -f "$HOME/.bashrc" ]; then
  source $HOME/.bashrc
fi
Restart your terminal.
