Rmagick在OSX Lion上构建本地宝石失败

Question

我正在处理我的图库，需要安装rmagick。然而，我一直无法这样做，因为会出现构建gem native extension失败的错误。我看过其他帖子，但他们的错误与我的不同。

我不知道如何让它工作。如果有人知道解决方案，那将是非常有帮助的！

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Answer 1

看起来你缺少一个名为libltdl的共享库，该库是构建gem所必需的。快速的谷歌搜索显示这个库由libtool包提供。

1. Try installing libtool and see if that fixes the problem. If you have Homebrew, this can be done with brew install libtool.

2. Apparently, there is a known issue on Mountain Lion where the suggested solution is to: update XCode to 4.4, update the XCode command line tools, install XQuartz (probably not required for this), and finally:

    brew uninstall imagemagick
    brew install --fresh imagemagick

在Mountain Lion上有一个已知的问题，但我不确定那个解决方案是否适用于你，因为你说你在Lion上。 - adamdunson

此外，您的构建日志显示它正在/usr/local/lib目录中查找libltdl，但我猜那里没有任何东西？ - adamdunson

你能否运行 find /usr -name 'libltdl.7.dylib' 并查看是否有任何结果？如果有，你可以尝试手动创建符号链接到 /usr/local/lib 目录下的此文件，例如 sudo ln -s /usr/lib/libltdl.7.dylib /usr/local/lib/libltdl.7.dylib，假设该文件存在于 /usr/lib 目录中。 - adamdunson

我曾经遇到过同样的问题。 解决方法是链接存放在地下室的库文件 ln -s /usr/local/Cellar/libtool/2.4.2/lib/libltdl.7.dylib /usr/local/lib/libltdl.7.dylib 具体步骤可以参考这里： http://nathan.vertile.com/blog/2013/02/14/installing_rmagick_on_108_with_homebrew/ - Ben

Answer 2

缺失的库由 libtool 包提供。您可以通过brew安装：

brew install libtool

安装完成后，您将收到以下信息：

Xcode 4.2 and below provide glibtool.

Generally there are no consequences of this for you. If you build your own software and it requires this formula, you'll need to add to your build variables:

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

将这些环境变量添加到您当前的环境中：

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

然后再次安装rmagick gem。我还更新了XCode命令行工具到最新版本。

- Fabrizio Regini

Answer 3

为了解决这个问题，我不得不卸载并重新安装RVM。然后运行'brew install ruby'以获取最新版本。然后运行'bundle'。

希望这能帮助那些遇到和我一样的错误的人。
