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

Question

我想使用带有载波的 rmagick gem 来上传和调整图像大小。

在我的 Local Rails 中..它运行良好。 但是当部署到服务器时.. 不起作用..

不知道为什么T^T

这里是 unicorn_error_log..

.../shared/bundle/ruby/2.0.0/gems/activesupport-4.0.0/lib/active_support/dependencies.rb:228:in `require': No such file to load -- RMagick (LoadError)

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

但奇怪的是在 server 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 ，生成调整大小的图像..

并在 server rails c 生产输入中

require 'RMagick'
=> false

这意味着 RMagick 已经在加载了，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!

作为引用，我已经在下面完成了..

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

请帮帮我.. 为什么不在服务器上工作？？

Answer 1

你是如何运行服务器的？

如果你的 Gemfile 有 rmagick 那么你需要使用 bundle exec 运行服务器

有时没有加载依赖项。 bundle exec 将确保始终加载依赖项。
