我试图部署一个Rails应用程序的乘客。
运行软件包时：
[ps93785]$ /usr/lib/ruby/gems/1.8/bin//bundle install 我得到这个：
Gemfile syntax error: /home/djwyatt/supplies.mighty-wash.com/public/Gemfile:33: syntax error, unexpected ':', expecting kEND gem 'sdoc', require: false
编辑1这是行31-34如果gem文件：
group :doc do # bundle exec rake doc:rails generates the API under doc/api. gem 'sdoc', require: false end
这在我的本地环境中工作得很好，不知道为什么会给我的VPS带来问题？
编辑2 （我正在开发Ruby 2.0，我的VPS是1.8）
这是我尝试升级时遇到的问题：
[ps93785]$ rvm upgrade 2.0 The source ruby was not a valid ruby string.
1.9.3也不起作用
编辑3 （这工作） rvm use 2.0然后bundle install worked fantastic 。 现在有一个新的问题 – 转储如下：

首先，您需要在Gemfile中使用ruby 1.8语法：
group :doc do gem 'sdoc', :require => false end
其次，我不确定最近的Passenger版本是否会支持Ruby 1.8。 即使这样，你也应该升级到至lessruby-1.9.3。
