ruby-on-rails - Rmagick 未能在 OSX Lion 上构建原生 gem

Question

我正在尝试在我的画廊上工作，我需要安装 rmagick。但是我一直无法这样做，因为我收到了无法构建 gem 原生扩展的错误。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。如果有人知道会有很大帮助的修复方法!

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

Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling.

Answer 1

您似乎缺少构建 gem 所需的名为 libltdl 的共享库。快速的 Google 搜索显示这是由 libtool package 提供的。 .

1. 尝试安装 libtool 看看是否能解决问题。如果您有 Homebrew ，这可以通过 brew install libtool 来完成。

2. 显然，有一个known issue在 Mountain Lion 上，建议的解决方案是:将 XCode 更新到 4.4，更新 XCode 命令行工具，安装 XQuartz(可能不需要)，最后:

    brew uninstall imagemagick
    brew install --fresh imagemagick
