Ruby on Rails，nginx，生產服務器上的乘客（無法加載此類文件 - ruby​​gems / path_support）

Question

我安裝了：

• Centos 6
• Ruby 1.9.3-rc1
• 乘客寶石和乘客nginx模塊（根據自己的源1.1.6編譯）
• 安裝導軌3.1.0
• Made / srv
• 鐵路新測試了
• 捆綁安裝
• 基於example / srv / test / public為nginx內的乘客制作了vhost
• service nginx stop && service nginx start
• ruby app加載好了index.html然后顯示...

單擊默認的/public/index.html中的“檢查應用程序環境”鏈接后，我收到此錯誤

無法加載此類文件 - ruby​​gems / path_support

Question: Anyone know how I can resolve the cannot load such file -- rubygems/path_support    error?

Answer 1

就我而言，我也遇到了這個問題：
（我的環境：Centos 5.8，rbenv 1.9.3p327，乘客3.0.19，nginx（由乘客編譯和安裝）。我用google搜索但沒有找到任何直接答案（關鍵字： rbenv, passenger, cannot load such file -- rubygems/path_support ），所以我在這里寫我的解決方案。

我已經檢查並將nginx用戶設置為root，而不是工作。 並將gem文件夾的所有權限更改為777.無效。

最后我得到了解決方案：將這兩行代碼添加到您的Nginx配置文件中：

passenger_default_user root;
passenger_default_group root;

所以現在你的nginx配置文件看起來像：

# /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 2

我有一個類似的問題，雖然我只為一個用戶安裝了rvm和ruby。 對我來說，解決方案是檢查應用程序文件是否由安裝了ruby的同一用戶所有。

Answer 3

我遇到了同樣的問題。 蒂莫是對的。

您的應用程序必須設置/ home / rvm_user /目錄。

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
