mini_magick错误的参数数量（0代表1）.resize

Question

我不确定这里发生了什么。

使用MiniMagick 3.3，一切工作正常，直到我试图调整大小。

这条线使我得到一个错误的号码参数错误：

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

这似乎像它应该根据文档做工精细。

这里的痕迹：

wrong number of arguments (0 for 1)

IMAGE_FILE = MiniMagick :: Image.open（“＃{RAILS_ROOT} /公/图片/ I /标准/＃{} baseimage.id /原来/＃{baseimage .image_file_name}“）

的IMAGE_FILE被返回正确的对象（我测试的一切，我说的每一步，它的所有工作，直到我调整）

尝试用值来替换字符串插值和测试，也许事情错在那里。

image_file.resize "250x250" 

如果这样的作品，那么你需要看看你的定义style，因为它可能无法正确定义，或者您也可以通过调用不正确的名称的方法。

尝试打开一个控制台应用程序，并运行一些示例代码MiniMagick只是这样，我们就能确保其工作：

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

如果在您的应用程序控制台进行再问题除了安装插件之外还存在。

好吧，以及它的安装方法，给你带来麻烦。使用捆绑器，您可以在供应商目录中安装依赖关系，从而使您可以在系统上安装它们的所有行为。尝试运行bundle install --path vendor/bundle查看docs here。
