Question

我遵循了如何在Bluehost上安装最新ruby版本的指令，并设法使用Rails-4.0.0-rc1获取Ruby-2.0.0-p195。我完全有能力运行irb并下载gem文件。

bash [~/rails/sample/config]# ruby -v
ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-linux]
bash [~/rails/sample/config]# rails -v
Rails 4.0.0.rc1
bash [~/rails/sample/config]# which ruby
/home6/username/ruby/bin/ruby
bash [~/rails/sample/config]# which rails
/home6/username/ruby/gems/bin/rails

我能够创建一个空应用程序，以测试它是否运行。我的.htaccess文件就像这样：

bash [~/rails/sample/config]# more ~/www/sample/.htaccess 
Options -MultiViews
PassengerResolveSymlinksInDocumentRoot on
#Set this to whatever environment you'll be running in
RailsEnv production
RackBaseURI /
PassengerAppRoot /home6/username/rails/sample
SetEnv GEM_HOME /home6/username/ruby/gems
bash [~/rails/sample/config]#

我的.bashrc文件如下所示：

bash [~]# more ~/.bashrc 
# .bashrc

export GEM_HOME=$HOME/ruby/gems
export GEM_PATH=$GEM_HOME:/usr/lib64/ruby/gem/1.8
export GEM_CACHE=$GEM_HOME/cache
export PATH=$HOME/ruby/gems/bin:$PATH
export PATH=$HOME/ruby/bin:$PATH
export PATH=$HOME/node/bin:$PATH

当我访问我的页面（www.somedomain.com/sample）时，我发现乘客有以下错误：

Ruby (Rack) application could not be started

The application has exited during startup (i.e. during the evaluation of config/environment.rb). 
The error message can be found below. To solve this problem, please follow any instructions in the
error message.

Error message: Rails 4 prefers to run on Ruby 2.0. You're running ruby 1.8.7 (2012-02-08 MBARI 8/0x6770

1.9.3 or newer to continue.

为什么乘客仍在寻找旧的红宝石并且没有看到新装置？或者是轨道问题？有没有办法让它使用正确的？我在某处错过了什么吗？

任何帮助都将不胜感激。

保尔。

这是因为服务器没有运行Phusion Passenger 4.只有Phusion Passenger 4.0.0支持多个Ruby版本，支持从bashrc读取环境变量。服务器当前正在运行3.x版本。

Bluehost上的Passenger看不到正确的Ruby版本
