我正在尝试从Github安装一个RoR应用程序，在运行bundle install时，我收到此错误：

Gem files will remain installed in /Users/adam/.rvm/gems/ruby-1.9.3-p327/gems/rmagick-2.13.1 for inspection.

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.

我试图运行gem install rmagick -v '2.13.1'，但我遇到了同样的错误。

我在Mac OS X Lion上运行。我错过了什么？

提前谢谢。

Answer 1

尝试运行：

brew link imagemagick

Answer 2

确保您有一个编译器。 XCODE命令行工具，或者只安装gcc。

Answer 3

我无法安装rmagick gem ......

首先正确安装Imagemagick

brew remove libtool
brew install libtool --universal

然后我可以使用此命令安装Imagemagick：

brew install imagemagick --build-from-source

然后正确安装了rmagick gem

当rmagick无法安装时我收到的错误消息如下所示：

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

这是针对Imagemagick 6.8.9-8和rmagick 2.13.2

Rails 3.2 + OSX：无法安装rmagick gem
