mini_magick錯誤的參數數量（0代表1）.resize

Question

我不確定這裏發生了什麼。

使用MiniMagick 3.3，一切工作正常，直到我試圖調整大小。

這條線使我得到一個錯誤的號碼參數錯誤：

image_file.resize "#{style.width}x#{style.height}" 

這似乎像它應該根據文檔做工精細。

這裏的痕跡：

wrong number of arguments (0 for 1)

IMAGE_FILE = MiniMagick :: Image.open（「＃{RAILS_ROOT} /公/圖片/ I /標準/＃{} baseimage.id /原來/＃{baseimage .image_file_name}「）

的IMAGE_FILE被返回正確的對象（我測試的一切，我說的每一步，它的所有工作，直到我調整）

上面的部分表示在引發ArgumentError＃ArticlesController更新

下面是完整的跟蹤：

嘗試用值來替換字符串插值和測試，也許事情錯在那裏。

image_file.resize "250x250" 

如果這樣的作品，那麼你需要看看你的定義style，因爲它可能無法正確定義，或者您也可以通過調用不正確的名稱的方法。

嘗試打開一個控制檯應用程序，並運行一些示例代碼MiniMagick只是這樣，我們就能確保其工作：

image = MiniMagick::Image.open("http://www.google.com/images/logos/logo.png") 
image.resize "5x5" 

如果在您的應用程序控制臺進行再問題除了安裝插件之外還存在。

好吧，以及它的安裝方法，給你帶來麻煩。使用捆綁器，您可以在供應商目錄中安裝依賴關係，從而使您可以在系統上安裝它們的所有行爲。嘗試運行bundle install --path vendor/bundle查看docs here。
