refinerycms图像无法加载 – 蜻蜓错误
我正在开发一个本地工作良好的refinerycms rails应用程序，现在我已将它移动到我的VPS，我遇到的问题是我通过refinerycms上传的图片没有加载，我一直在阅读我需要升级我的imagemagick版本。 我从6.2.8升级到6.7.8。 现在图像都加载到某些页面上，但不在管理员端加载。
是什么导致了这个问题？ 这是错误的堆栈跟踪。

我已经按照这里的建议将下面的代码添加到我的config / application.rb文件中，它帮助显示了一些文件，但是我仍然无法通过应用程序上传文件，部分堆栈跟踪如下所示。
config / application.rb包含这个
initializer 'override-image-magick-paths', :after => 'attach-refinery-images-with- dragonfly' do app=Dragonfly[:refinery_images] app.configure_with(:imagemagick) app.configure do |c| c.convert_command = "/usr/local/bin/convert" # defaults to "convert" c.identify_command = "/usr/local/bin/identify" # defaults to "identify" end end

我从/ usr / bin / convert – > / usr / local / bin / convert和/ usr / bin / identify – > / usr / local / bin / identify创建了一个符号链接，这似乎解决了我的问题。
$ cd /usr/bin $ ln -s /usr/local/bin/convert convert $ ln -s /usr/local/bin/identify identify
我假设即使我在config / application.rb文件中指定了它，蜻蜓仍然没有拿起我的转换位置并识别。
我只是重新安装了imagemagick并且工作正常。
您可能必须提供convert的完整路径：
config/initializers/dragonfly.rb: app.configure do |c| c.convert_command = "/usr/bin/convert" end
更改/usr/bin/convert为正确的convert路径，您可以通过在VPS shell上运行whereis convert找到它。
文档中的更多细节。
尝试安装refinery-images gem：
Gemfile: gem 'refinerycms-page-images', '~>1.0.3' //refinery v1 compatible (v2 available also)
然后在你的模型中：
belongs_to :imagesizeyouwant, :class_name => 'Image'
如果你看一下Image类，你会看到一个非常好的处理图像的设置。 您可以在管理工具的Refinery的“设置”页面中添加图像大小。 如果你有一个自定义引擎，只需更改：imagesizeyouwant到那个大小（我的是：缩略图）。
发布图像时，请查看identify命令的输出并尝试自行运行。 有可能您的系统具有用于ImageMagick二进制文件的不同参数，或者不能理解发送给它的维度。 尝试发布实际命令的输出Dragonfly在shell中调用，以便我们可以更好地查看。
