未初始化的常量CarrierWave [英] uninitialized constant CarrierWave

问题描述

我正在使用乘客和capistrano部署我的第一个Rails应用程序。

I am deploying my first rails app using passenger and capistrano.

一切都很好，直到尝试在浏览器中启动该应用程序时遇到此错误。

every thing is fine until i faced this error when I tried to launch the app in the browser.

Error message:
   uninitialized constant CarrierWave

Exception class:
   NameError

您可以在 http://test.ajhezaty.com/

该站点在本地运行良好，并且CarrierWave可以正确上传图像。

the site works perfectly locally and CarrierWave uploading the image correctly.

我尝试通过运行

sudo /etc/init.d/httpd2 restart

但它没有解决问题。

供您参考，服务器上安装的gem

for your information the gem installed on the server

 $ gem list | grep carrierwave
 carrierwave (0.6.1)

推荐答案

您需要像这样向您的 application.rb 文件中添加载波：

You need to add carrierwave to your application.rb file like this:

require File.expand_path('../boot', __FILE__)

require 'rails/all'

require 'carrierwave'

if defined?(Bundler)
  # Bundler stuff
end

# Rest of file ommited.

这对我使用nginx / unicorn进行生产很有用。不要忘记重启独角兽服务器。

This worked for me in production using nginx/unicorn. Don't forget to restart your unicorn server.
