我得到了流浪箱。当我使用vagrant ssh登录时，我在shell中执行：
cd app
bundle exec cucumber
并进行黄瓜测试。
现在我需要从我的主机操作系统外壳执行bundle exec whatever。
我试过了：
~/vbox > vagrant ssh -c 'cd app; bundle exec cucumber'
https://github.com/rsim/oracle-enhanced.git (at rails4) is not yet checked out. Run `bundle install` first.
Connection to 127.0.0.1 closed.
~/vbox > vagrant ssh -c 'cd app; pwd; ls; bundle list'
/home/vagrant/app
account bin certs config.ru db features Gemfile.lock log Rakefile script spec vbox
app Capfile config data Gemfile lib public README.md tmp vendor
Gems included by the bundle:
https://github.com/rsim/oracle-enhanced.git (at rails4) is not yet checked out. Run `bundle install` first.
Connection to 127.0.0.1 closed.
~/vbox > vagrant ssh -c 'ruby -v; rvm list'
ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-linux]

=* ruby-2.0.0-p353 [ x86_64 ]

如何在与我交互执行命令完全相同的环境中执行命令？
更新：

然后我注意到来自主机操作系统的命令使用gemset ds-cabinet
GEM_HOME=/home/vagrant/.rvm/gems/ruby-2.0.0-p353@ds-cabinet
而客户操作系统外壳中的命令使用gemset global
GEM_PATH=/home/vagrant/.rvm/gems/ruby-2.0.0-p353@global
使用gemset ds-cabinet是因为存在包含ds-cabinet字符串的app/.ruby-gemset文件。
当我明确指定ruby版本和gemset时，来自主机操作系统的命令成功了。
vagrant ssh -c 'cd app; rvm use ruby-2.0.0-p353@global; xvfb-run bundle exec cucumber'
结论：
尽管有指向ds-cabinet gemset的app/.ruby-gemset，但实际上Bundler在来宾操作系统外壳中本地调用时使用了global gemset，而在从主机操作系统作为远程命令调用时使用的是ds-cabinet gemset，该gemset最终为空。
因此，我将app/.ruby-gemset设置为global，主机操作系统命令做得很好。
