Question

最近我将我的Mac更新为El Capitan并重新安装（使用Homebrew）ImageMagick 6.9.2-7

不幸的是bundle install无法正常工作，因为RMagick无法构建。

这里是堆栈跟踪：

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

extconf failed, exit code 1

我已经尝试了几种基于互联网的不同解决方案，但似乎没有解决这个错误。

通过以下操作，我总是收到错误：

1) C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.9.2-7/include/ImageMagick-6/ gem install rmagick -v '2.13.2'



2) gem install rmagick --version=2.13.2 --platform=ruby -- --with-opt-lib="h:/ImageMagick-6.9.2-7/lib" --with-opt-include="h:/ImageMagick-6.9.2-7/include"

3) $ cd /usr/local/Cellar/imagemagick/6.9.2-7/lib
$ ln -s libMagick++-Q16.6.dylib   libMagick++.dylib
$ ln -s libMagickCore-Q16.2.dylib libMagickCore.dylib
$ ln -s libMagickWand-Q16.2.dylib libMagickWand.dylib

错误仍然相同：

The compiler failed to generate an executable file. (RuntimeError)

您必须先安装开发工具。

我还将xcoce更新为7.1.1

我使用ruby-1.9.3-p327和RVM

提前致谢。

Answer 1

您需要更新Xcode并安装命令行工具（UNION）。

Answer 2

这些都不是孤立地为我工作，但所有它们的运行似乎都有效：

xcode-select --install
brew unlink imagemagick
brew uninstall --force imagemagick
brew update
brew doctor
brew install imagemagick

这可能有点矫枉过正，但最终对我有用。
