Ruby on Rails、nginx、生产服务器上的乘客（无法加载此类文件 -- ruby​​gems/path_support）

Question

我安装了：

• Centos 6
• Ruby 1.9.3-rc1
• Passenger gem 和passenger nginx 模块（根据自己的源代码1.1.6 编译）
• 安装的rails 3.1.0
• 制造 /srv
• 是否进行了新的 rails 测试
• 捆绑安装
• 根据示例 /srv/test/public 为 nginx 内的乘客制作 vhost
• 服务 nginx 停止 && 服务 nginx 启动
• ruby 应用加载正常 index.html 显示，但随后...

单击默认 /public/index.html 中的“检查应用程序环境”链接时，我收到此错误

Answer 1

虽然我只为一个用户安装了 rvm 和 ruby​​，但我也遇到了类似的问题。对我来说，解决方案是检查应用程序文件是否属于安装了 ruby​​ 的同一用户。

Answer 2

就我而言，我也遇到了这个问题：
（我的环境：Centos 5.8，rbenv 1.9.3p327，passenger 3.0.19，nginx（由乘客编译和安装）。我用谷歌搜索，但没有找到任何直接答案（关键字：rbenv, passenger, cannot load such file -- rubygems/path_support），所以我写了我的解决方案在这里。

我已检查并将 nginx 用户设置为 root，但无法正常工作。 并将gem文件夹的所有权限更改为777。不起作用。

我终于找到了解决方案：将这两行代码添加到您的 Nginx 配置文件中：

passenger_default_user root;
passenger_default_group root;

所以现在你的 nginx 配置文件看起来像：

# /opt/nginx/config/nginx.conf
user  root;  # seems this line of code doesn't take effect.
http {
  passenger_root /root/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/passenger-3.0.19;
  passenger_ruby /root/.rbenv/versions/1.9.3-p327/bin/ruby;

  # these lines are the key!!!
  passenger_default_user root;
  passenger_default_group root;

  server {
    listen 80;
    root <your_rails_project_public_folder>;
    passenger_enabled on;
  }
}

Answer 3

我遇到了同样的问题。 蒂莫是对的。

您的应用程序必须设置 /home/rvm_user/ 目录。

示例：

# vi /etc/conf/httpd.conf
LoadModule passenger_module
/home/rvm_user/.rvm/gems/ruby-1.9.3-rc1/gems/passenger-3.0.9/ext/apache2/mod_passenger.so
PassengerRoot /home/rvm_user/.rvm/gems/ruby-1.9.3-rc1/gems/passenger-3.0.9
PassengerRuby /home/rvm_user/.rvm/wrappers/ruby-1.9.3-rc1/ruby

<VirtualHost *:80>
ServerName www.yourhost.com
DocumentRoot /home/rvm_user/your_application/public
<Directory /home/rvm_user/your_application/public>
AllowOverride all
Options -MultiViews
</Directory>
</VirtualHost>

# chmod 755 /home/rvm_user/

# /etc/rc.d/init.d/httpd restart
