但是,我放了流程代码:
gem 'rmagick', :require => false
错误:

请帮助我,谢谢!
最佳答案
MagickWand.h 是 ImageMagick 的一部分而 RMagick 安装程序找不到它。看来您需要在系统上安装 ImageMagick,或者如果安装了它,则需要将库添加到 gem 安装程序可以看到的路径。如果您的系统上没有安装 ImageMagick 或 GraphicsMagick,RMagick 将无法工作。
更新的答案 由于您使用的是 Windows,因此您需要手动下载 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,然后按照您将在包中找到的 README.html 文件中的说明进行操作。

我想你可能想卸载你已经安装的 imagemagick 版本,以防发生任何冲突。手动安装 gem 后,您应该可以将其放入 Gemfile 并进行捆绑安装。由于没有在 Windows 上使用过 rmagick,我不确定您是将 gem 称为“rmagick”还是“rmagick-win32”。手动安装 gem 后,您可能可以通过运行“gem list”命令来解决这个问题。查看出现了哪一个并将其放入您的 Gemfile,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。
