更新RMagick和Imagemagick是一个痛苦的期待.我用自制软件更新了Mac上的Imagemagick版本(MacOS El Capitan版本10.11.5),用于Ruby 2.3中的一个项目6.9.5-9

$ convert --version
Version: ImageMagick 6.9.5-9 Q16 x86_64 2016-09-09

现在Ruby 1.8.7中的一个旧项目拒绝使用错误消息"这个RMagick的安装配置了ImageMagick 6.8.9但ImageMagick 6.9.5-9正在使用中".因此我卸载了"rmagick",但无法重新安装

$ gem install rmagick -v 2.16.0

我见过其他人在Mountain Lion上安装RMagick同样的问题但是没有一个建议的解决方案允许我成功安装rmagick.

这是我得到的错误消息:

我使用脚本安装ImageMagick http://github.com/masterkain/ImageMagick-sl

过了一会儿,我安装了ImageMagick.

然后我跑了sudo gem install rmagick并得到了

我正在使用Ruby 1.9.2和Rails 3在OSX Snow Leopard中工作.任何想法？

我想在我的本地机器上运行一个项目.我在Mac OS系统上安装了Ruby和Rails.它运作正常.我可以创建一个新项目,并且可以正常运行它而不会出现任何错误,但是当我尝试运行现有项目时,它说我们必须这样做bundle install.当我运行该命令时,我收到以下错误:

"An error occurred while installing rmagick (2.13.2), and Bundler cannot continue.
Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling."

当我运行gem install rmagick -v '2.13.2'它时给我以下错误:

我在安装rmagick时遇到问题.我正在使用ruby on rails框架开发我的项目.我在我的gemfile中包含了rmagick gem.我收到以下错误消息:

checking for ImageMagick version >= 6.4.9... no
Can't install RMagick 2.13.4. You must have ImageMagick 6.4.9 or later.

我使用brew安装了imagemagick:

 imagemagick-6.8.9-8 already installed

imagemagick文件夹位于/ usr/local/Cellar目录中

在我的终端:

我在很长一段时间运行后,Debian服务器和升级的所有软件包(apt-get update,apt-get upgrade,apt-get distro-upgrade).然后rmagick不再工作了因为imagemagick被更新了.

所以我跑了:

gem uninstall rmagick
bundle install

然后我得到了这个:

我正在使用载波，但我遇到了这个问题：假设项目交付后，您需要添加一个区域，其中需要以不同的大小显示系统中的图像。我不想为系统中已经存在的每个图像重新生成新的尺寸。我希望能够在需要视图时生成（并缓存它）。像这样：“ />。如果新的尺寸500x150已经存在，则返回缓存的URL，否则生成它并返回缓存的URL

我非常喜欢Carrierwave，但很遗憾，它没有开箱即用的即时调整大小功能。所有人都说添加此功能应该很简单，但是我什么也没发现。唯一接近的是此上传器https://gist.github.com/DAddYE/1541912 我必须对其进行修改才能使其正常工作，所以这里是我的版本

  include CarrierWave::RMagick

  #  process :resize_to_fill => [100,100]
  #end

  #version :thumb_square do

  #version :full do

  def re_size(string_size)

      return self

    uploader.versions.clear

我通过提供MagickWand.h的路径尝试了一切,我已经安装了命令工具.谁能帮我吗 ？
