Carrierwave/RMagick NoMethodError升級到紅寶石2.0後

-1

我升級了我的應用程序從紅寶石1.9.3到紅寶石2.0，保持我的大部分寶石沒有升級。一切工作正常，但是當我嘗試上傳的圖像，我得到這個錯誤：Carrierwave/RMagick NoMethodError升級到紅寶石2.0後

NoMethodError - undefined method `[]=' for nil:NilClass: 
    app/uploaders/image_uploader.rb:91:in `block in optimize' 
    /home/stefpe/.rvm/gems/[email protected]/bundler/gems/carrierwave-5ee108128b40/lib/carrierwave/processing/rmagick.rb:263:in `manipulate!'

    /home/stefpe/.rvm/gems/[email protected]/bundler/gems/carrierwave-5ee108128b40/lib/carrierwave/uploader/callbacks.rb:18:in `with_callbacks'

的image_uploader.rb基於/carrierwave/processing/rmagick.rb例如manipulate功能：

def optimize 
    manipulate! do |img, index, options| 
     options[:write] = { 
    :quality => 50, 
    :depth => 8, 
    :interlace => "Magick::PlaneInterlace" 
     } 
     img.strip! 
    end 
    end

配置：服務器：Heroku的，本地開發：Linux的

紅寶石1.9.3 - > 2.0

個軌3.2.13

carrierwave 0.6.2

rmagick 2.13.1

霧1.3.1

任何想法，爲什麼會出現與紅寶石2.0.0不兼容？

預先感謝您！

你會很好，包括91行的摘錄，因爲錯誤味精說： –

我所做的：命令和apt-get安裝libmagickwand-dev的

然後創業板安裝rmagick

它的工作。看到： rmagick gem install "Can't find Magick-config"

你應該嘗試更新一些寶石，carrierwave可能沒有在四月已與紅寶石2完全兼容2012

進一步激勵：Carrierwave didn't甚至傳遞選項加入到傳遞給manipulate!塊直到0.7。

對我來說有效的是在操作結束時返回圖像！在你的情況：

def optimize 
    manipulate! do |img, index, options| 
    options[:write] = { 
     :quality => 50, 
     :depth => 8, 
     :interlace => "Magick::PlaneInterlace" 
    } 
    img.strip! 
    img 
    end 
end
