imagemagick - 检查 ImageMagick 版本 >= 6.4.9... 否 无法安装 RMagick 2.13.4。您必须有 ImageMagick 6.4.9 或更高版本

Question

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.

我已经使用 brew 安装了 imagemagick:

 imagemagick-6.8.9-8 already installed

imagemagick 文件夹位于/usr/local/Cellar 目录中

在我的终端中:

Zoulfias-iMac:Myapp zoulfiahall$ rvm 使用 ruby​​-2.0.0-p481

Gem files will remain installed in /Users/zoulfiahall/.rvm/rubies/
ruby-2.0.0-  p481/lib/ruby/gems/2.0.0/gems/rmagick-2.13.4 for inspection.

任何建议将被认真考虑。

这在 ubuntu 上对我有用。

$ sudo apt-get install imagemagick
$ sudo apt-get install libmagickwand-dev

现在再试一次。

$ bundle install
