我有一个由 Geminabox 运行的私人 gemserver。要在那里发布任何 gem，有一个命令gem inabox my-gem.gem -g $HOST。
我正在编写用于自动发布新 gem 版本的脚本。
所以我有类似的东西：
`gem install geminabox --no-ri --no-rdoc`
`gem inabox my-super-gem.gem`
问题是它返回以下内容：
Successfully installed reentrant_flock-0.1.0
Successfully installed multipart-post-2.0.0
Successfully installed faraday-0.13.1
Successfully installed nesty-1.0.2
Successfully installed httpclient-2.8.3
Successfully installed builder-3.2.3
Successfully installed mustermann-1.0.1
Successfully installed rack-2.0.3
Successfully installed rack-protection-2.0.0
Successfully installed tilt-2.0.8
Successfully installed sinatra-2.0.0
Successfully installed geminabox-0.13.9
12 gems installed
ERROR: While executing gem ... (Gem::CommandLineError)
Unknown command inabox
当我在控制台中手动执行相同操作时，一切正常。如果我将这些命令放入.sh脚本中也是一样的：
#!/bin/bash
set -e
gem install geminabox --no-ri --no-rdoc
gem inabox -g $RUBYGEMS_HOST my-awesome.gem
但是，再一次，如果我从 ruby 调用这个脚本，它不会出现同样的错误（Unknown command inabox）：
system('script/upload_gem.sh')
我需要完全使用 Ruby 中的脚本。任何想法为什么它不起作用？
