ruby-on-rails-3 - Rails 3 和 RefineryCMS - Dragonfly::Shell::CommandFailed in Refinery::Admin::ImagesController#create

Question

看起来很多人都有同样/相似的问题，并且我在 SO here 上找到了一些修复报告.不幸的是，他们不为我工作。我正在运行 MacOS Lion。这是我到目前为止所做的:

1) 标准 RefineryCMS 安装。除了上传图片外，运行良好。2)遇到问题后，我根据 Dragonfly 添加了一个配置文件 docs :

# configure/initializers/dragonfly.rb
require 'dragonfly/rails/images'

3) 那没有用。我重新安装了 ImageMagick。已确认安装了 ImageMagick:

# whereis convert
/usr/bin/convert
# whereis identify
/usr/bin/identify

4) 这并没有解决问题，所以我为/usr/bin 和/usr/local/bin 设置了符号链接(symbolic link):

lrwxr-xr-x  1 root  wheel  22 Aug  4 11:00 /usr/bin/convert -> /opt/local/bin/convert
lrwxr-xr-x  1 root  wheel  23 Aug  4 11:01 /usr/bin/identify -> /opt/local/bin/identify
lrwxr-xr-x  1 root  admin  22 Aug  4 11:06 /usr/local/bin/convert -> /opt/local/bin/convert
lrwxr-xr-x  1 root  admin  23 Aug  4 11:07 /usr/local/bin/identify -> /opt/local/bin/identify

5) 这没有用，所以我根据 Dragonfly 文档和一些额外的 instructions 设置了一个新的配置文件:

# config/initializers/dragonfly.rb
require 'dragonfly'

app = Dragonfly[:images]
app.configure_with(:imagemagick)
app.configure_with(:rails)

app.define_macro(ActiveRecord::Base, :image_accessor)

app.configure do |c|
  c.convert_command = "/opt/local/bin/convert"          # defaults to "convert"
  c.identify_command = "/opt/local/bin/identify"        # defaults to "identify"
  c.log_commands = true                                 # defaults to false
end

6) 那并没有解决它。基于 GitHub issue我加了这个

# config/application.rb
module Refincmstest
  class Application < Rails::Application
    # trying a fix for image magic
    initializer 'override-image-magick-paths', :after => 'attach-refinery-images-with-dragonfly' do
      Dragonfly[:refinery_images].configure do |c|
        c.convert_command = "/opt/local/bin/convert"          # defaults to "convert"
        c.identify_command = "/opt/local/bin/identify"        # defaults to "identify"
      end
    end
  end
end

那是行不通的。这是控制台输出，如果这有帮助的话:

我没主意了。关于下一步去哪里有什么建议吗？

Answer 1

我在升级到 OS X Yosemite 后遇到了这个错误。因为我用 brew 安装了 imagemagick，所以我运行 brew doctor 并报告了各种问题，其中还有一个符号链接(symbolic link)问题。我按照说明解决了所有问题，现在它又能正常工作了。
