An error occurred while installing rmagick (2.13.1), and Bundler cannot continue. 
Make sure that `gem install rmagick -v '2.13.1'` succeeds before bundling.

我想跑gem install rmagick -v '2.13.1'，但我得到了同样的错误。

我在Mac OS X Lion上运行。我错过了什么？

预先感谢您。

那么，你的意思是什么？Yar？我现在有点迷路了。 – user984621

尝试运行：

brew link imagemagick

如果你得到'不可写'的错误，下面的答案应该有所帮助：http://stackoverflow.com/a/16844923/3507417 –

确保你有一个编译器。 XCODE命令行工具，或者只安装gcc。

我已经安装了'XCODE命令行工具'。 – user984621

你安装了ImageMagick吗？ 'brew install imagemagick' – gmalette

如果你已经安装了自制软件'brew doctor'。它可能会给你一些提示，指出你的系统中缺少安装本地库的信息。 –

我无法安装rmagick宝石要么...

为了得到正确安装ImageMagick的我第一次

brew remove libtool 
brew install libtool --universal

然后我就能够安装Imagemagick使用此命令：

brew install imagemagick --build-from-source

然后rmagick宝石正确安装

时rmagick不会安装看起来像我得到的错误信息：

linking shared-object RMagick2.bundle 
ld: file not found: /usr/local/lib/libltdl.7.dylib for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 
make: *** [RMagick2.bundle] Error 1 

make failed, exit code 2

这是对的ImageMagick 6.8.9-8和rmagick 2.13.2
