我想使用带有载波的 rmagick gem 来上传和调整图像大小。
在我的本地 Rails 中.. 效果很好。但是当部署到服务器时..不起作用..
不知道为什么T^T
这里 unicorn_error_log ..

但奇怪的是在服务器rails c生产中
a = Word.find(2)
a.image.recreate_versions!(:image, :thumb)
这很好用，没有错误！！！thumb_~~.jpg , 调整大小的图像生成..
并在服务器rails c生产输入
require 'RMagick'
=> false
这意味着 RMagick 已经在加载，对吧？
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
第 5 行错误！
供参考，我已经在下面完成了..
apt-get install libmagickwand-dev imagemagick
in Gemfile | gem 'rmagick', :require => 'RMagick'
请帮助我..为什么不在服务器上工作？
