rails在生产服务器中包含CarrierWave :: RMagick错误

Question

我想使用带载波的rmagick gem来上传图像并调整其大小。

在我的本地导轨..它运作良好。 但是当部署到服务器..不..作品

我不知道为什么T^T

这里unicorn_error_log ..

from .../releases/20131018192701/app/uploaders/image_uploader.rb:3:in `<top (required)>' 

，但奇怪的是在服务器导轨c的制备

a = Word.find(2) 
a.image.recreate_versions!(:image, :thumb) 

这很好，没有错误！ thumb_ ~~ .JPG，生成调整后的图像..

和在服务器导轨c的制备输入

require 'RMagick' 
=> false 

这意味着RMagick已经加载，是吗？

啊！这是我的image_uploader.rb

3: class ImageUploader < CarrierWave::Uploader::Base 

5: include CarrierWave::RMagick 

52: version :thumb do 
53:  process :resize_to_limit => [400, 400] 
54: end 

line 5 error！

参考，我已经完成了下面..

apt-get install libmagickwand-dev imagemagick 
in Gemfile | gem 'rmagick', :require => 'RMagick' 

请帮助我.. 为什么在服务器无法正常工作？

如何运行服务器？

如果您的Gemfile有rmagick那么你需要使用捆绑高管

有时依赖不加载运行服务器。 bundle exec将确保始终加载依赖项。
