Rmagick未能在OSX Lion上创建原生Gem

Question

我正在尝试在我的画廊上工作，而且我需要安装rmagick。但是，我一直无法这样做，因为我无法构建gem本机扩展时遇到错误。我看到其他帖子，但他们的错误与地雷不同。

我不知道如何让它工作。如果有人知道一个修复会有很大的帮助！

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. 

Answer 1

要解决这个问题，我必须卸载然后重新安装RVM。然后运行'brew install ruby​​'以获取最新版本。然后'捆绑'。

我希望这可以帮助其他人遇到我所做的确切的错误。

Answer 2

看起来你错过了一个名为libltdl的共享库，它是构建gem所必需的。快速Google搜索显示，这是由libtool package提供的。

1. 尝试安装libtool，看看是否解决了问题。如果您有Homebrew，则可以使用brew install libtool完成此操作。

2. 显然，对山狮一known issue，其中提出的解决方案是：更新的XCode 4.4，更新Xcode的命令行工具，安装XQuartz（可能不需要这个），最后：

   brew uninstall imagemagick 
   brew install --fresh imagemagick 
   

Answer 3

缺少的库是由libtool包提供的。您可以通过BREW安装：

酿造INSTAL libtool的

安装后你得到这个消息：

的Xcode 4.2和下面提供glibtool。

通常这对你没有任何后果。如果你建立你自己的 软件，它需要这个公式，你需要添加到您的 生成变量：

LDFLAGS: -L/usr/local/opt/libtool/lib 
CPPFLAGS: -I/usr/local/opt/libtool/include 

添加这些环境变量当前环境：

export LDFLAGS="-L/usr/local/opt/libtool/lib" 
export CPPFLAGS="-I/usr/local/opt/libtool/include" 

然后再安装rmagick gem。我也将XCode命令行工具更新到最新版本。
