在 Maverick 10.9.3 上安装 ImageMagick 时遇到问题

Question

最近两天我正在与 ImageMagick 和 rmagick gem 的配置作斗争。我在 SO 上找到了几个主题，但没有一个能帮助我解决这个问题。

最近，我也尝试更新rvm，但它也没有帮助我。当我现在运行bundle update 时，输出为：

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

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.

现在如何进行 - 要删除哪个 ImageMagick？或者，还有什么我忽略的吗？

Answer 1

错误提示问题：

警告：发现多个 ImageMagick 安装。这可以 在运行时引起问题。 /usr/local/bin/Magick-config 报告版本 6.8.6 Q8 安装在 /usr/local /opt/ImageMagick/bin/Magick-config 报告版本 6.8.8 Q16 安装在 /opt/ImageMagick 使用来自 /usr/local 的 6.8.6 Q8。

还有：

你必须先安装开发工具。

您可以通过输入命令xcode-select --install 并单击安装

来执行此操作

这会安装 gcc 以及编译 ImageMagick 和其他源所需的其他东西。

现在删除您当前安装的 ImageMagick 之一。或者删除两者并使用自制软件安装 ImageMagick：

brew update
brew install imagemagick

如果这不起作用，这里有一些我发现的链接可能会有所帮助：
