未初始化常量Capistrano (NameError)

Question

rvm 1.14.5，rvm-capistrano (1.2.2)和capistrano (2.12.0)我的Gemfile是：

group :development, :test do
   gem 'rvm-capistrano'
   gem 'capistrano'
end

当我尝试启动passenger时，我一直看到这个错误：

[ pid=4691 thr=76294140 file=utils.rb:176 time=2012-07-04 11:37:06.179 ]: *** Exception NameError in PhusionPassenger::Rack::ApplicationSpawner (uninitialized constant Capistrano) (process 4691, thread #<Thread:0x9184ff8>):

在这里只是尝试一下，但请确保在安装包时排除了开发和测试组。

捆绑包安装--无需测试开发

由于某种原因，您的应用程序似乎正在尝试加载rvm-capistrano。
