我有以下配置：
该应用程序正在使用rvm很好地哼唱
现在我正在尝试使用不同的ruby和rails版本的sub uri。我正在使用这篇文章作为模板：
我的主要应用程序是www / gi，我的子uri是www / r5
作为基础测试，我在gi / public和r5 / public都有一个index.html。
我可以http到gi / index.html AND gi / r5 / index.html
然后我使用索引方法在r5中创建了一个简单的'start'控制器，并尝试通过http连接到gi / r5 / start / index.html .....并且我找不到404。
这是我的nginx.conf文件：

我究竟做错了什么？
我在phusionpassenger.com网站上发现了这个：
https://www.phusionpassenger.com/library/config/nginx/reference/#passenger_ruby
我做了以下事情：
>which passenger-config
/home/nexargi/.rvm/gems/ruby-1.9.3-p484@global/bin/passenger-config
>rvm use 2.4.0
Using /home/nexargi/.rvm/gems/ruby-2.4.0
>/home/nexargi/.rvm/gems/ruby-1.9.3-p484@global/bin/passenger-config --ruby-command
出现以下错误消息：
/home/nexargi/.rvm/rubies/ruby-1.9.3-p484/lib/ruby/site_ruby/1.9.1/rubygems.rb:289:in `find_spec_for_exe': can't find gem passenger (>= 0.a) with executable passenger-config (Gem::GemNotFoundException)
from /home/nexargi/.rvm/rubies/ruby-1.9.3-p484/lib/ruby/site_ruby/1.9.1/rubygems.rb:308:in `activate_bin_path'
from /home/nexargi/.rvm/gems/ruby-1.9.3-p484@global/bin/passenger-config:23:in `<main>'
请注意，ruby 2.4.0是r5 sub-uri所需的ruby。这确实看起来像问题。但是我不知道如何纠正它。
为了绝对肯定，我接着做了以下事情：
>rvm use 1.9.3-p484
Using /home/nexargi/.rvm/gems/ruby-1.9.3-p484
>/home/nexargi/.rvm/gems/ruby-1.9.3-p484@global/bin/passenger-config --ruby-command
这给出了预期的正确信息：
passenger-config was invoked through the following Ruby interpreter:
Command: /home/nexargi/.rvm/gems/ruby-1.9.3-p484/wrappers/ruby
Version: ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]
To use in Apache: PassengerRuby /home/nexargi/.rvm/gems/ruby-1.9.3-p484/wrappers/ruby
To use in Nginx : passenger_ruby /home/nexargi/.rvm/gems/ruby-1.9.3-p484/wrappers/ruby
To use with Standalone: /home/nexargi/.rvm/gems/ruby-1.9.3-p484/wrappers/ruby /home/nexargi/.rvm/gems/ruby-1.9.3-p484@global/gems/passenger-4.0.37/bin/passenger start
## Notes for RVM users
Do you want to know which command to use for a different Ruby interpreter? 'rvm use' that Ruby interpreter, then re-run 'passenger-config --ruby-command'.
看来现有网站的乘客是使用RVM gem install等安装的，这不是目前推荐的做事方式。
我找到了这个：
https://www.phusionpassenger.com/library/install/nginx/install/oss/xenial/
我跟着这个，从RVM内部移走旧乘客后，一切都很好。
