链接红宝石到RVM [英] Link ruby to RVM
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
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。

第一个列表在RVM中的ruby版本
rvm list

ruby-1.9.3-p484 [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]

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
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.
