Answer 1

MagickWand.h是ImageMagick的一部分，RMagick安装程序无法找到它。您似乎需要在系统上安装ImageMagick，或者如果安装了ImageMagick，则需要将库添加到gem安装程序可以看到的路径中。如果没有在系统上安装ImageMagick或GraphicsMagick，RMagick将无法运行。

更新的答案 由于您使用的是Windows，因此需要手动下载gem并进行安装。安装常见问题解答说：

使用rmagick-win32 gem。此gem与ImageMagick Windows安装程序的副本捆绑在一起，因此您无需下载自己的副本。从RubyForge上的RMagick项目页面下载rmagick-win32 gem，将其解压缩到一个临时目录中，并按照包中找到的README.html文件中的说明进行操作。

http://rubyforge.org/projects/rmagick/

我想您可能想要卸载已安装的imagemagick版本，以防出现任何冲突。手动安装gem后，您应该可以将它放在Gemfile中并捆绑安装。没有在windows上使用rmagick，我不确定你是否将gem引用为“rmagick”或“rmagick-win32”。手动安装gem后，您可以通过运行“gem list”命令来解决这个问题。查看哪一个出现并将其放入您的Gemfile中，以便它可以找到已安装的版本.Bundler将使用此gem而不是尝试安装新的。

这段代码可以解决问题...

require 'RMagick' 不 require 'rmagick'
