我已经ruby 2.0使用rvm. 我是新手tmux。

我在.tmux.conf这个配置中使用 zsh

set-option -g default-shell /bin/zsh 
set-option -g default-command "/bin/zsh -i"

我也加载了 rvm 路径.zshrc

source /Users/mgpyone/.rvm/scripts/rvm

现在，这些是我在会话中尝试时的配置。tmux

which ruby说/Users/mgpyone/.rvm/rubies/ruby-2.0.0-p0/bin/ruby

where ruby返回为

/Users/mgpyone/.rvm/rubies/ruby-2.0.0-p0/bin/ruby 
/Users/mgpyone/.rvm/bin/ruby 
/Users/mgpyone/.rvm/bin/ruby

但为什么gem env显示我的Ruby executable路径设置为系统路径而不是rvm

RubyGems Environment:
  - RUBYGEMS VERSION: 2.0.3
  - RUBY VERSION: 2.0.0 (2013-02-24 patchlevel 0) [x86_64-darwin12.3.0]
  - INSTALLATION DIRECTORY: /Users/mgpyone/.rvm/gems/ruby-2.0.0-p0
  - RUBY EXECUTABLE: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
  - EXECUTABLE DIRECTORY: /Users/mgpyone/.rvm/gems/ruby-2.0.0-p0/bin
  - RUBYGEMS PLATFORMS:
    - ruby
    - x86_64-darwin-12
  - GEM PATHS:
     - /Users/mgpyone/.rvm/gems/ruby-2.0.0-p0
     - /Users/mgpyone/.rvm/gems/ruby-2.0.0-p0@global
  - GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :backtrace => false
     - :bulk_threshold => 1000
     - :benchmark => false
     - :sources => ["https://rubygems.org"]
  - REMOTE SOURCES:
     - https://rubygems.org

而且我无法运行类似的东西，rake因为我认为它可以使用 System Ruby 执行。

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby app.rb -s puma
app.rb:1:in `require': no such file to load -- sinatra (LoadError)
        from app.rb:1
        rake aborted!
        Command failed with status (1): [/System/Library/Frameworks/Ruby.framework/...]
        /Users/mgpyone/work/rb/fileserver/Rakefile:9
        (See full trace by running task with --trace)

我该如何解决这个问题？

很可能你在启动 tmux 时设置了 $GEM_HOME 或 $GEM_PATH。由于 tmux 继承了这些环境变量，它下包含的每个 shell 都将受到这些设置的影响，而不管 rvm 设置如何。

检查tmux showenv -g GEM_HOME（或 GEM_PATH）
