麻烦在mac 10.9上安装rmagick gem

Question

我已经尝试了我在git上找到的所有SO和解决方案,但没有运气.我试图在一个新的mbp retina w/mavericks上的现有项目上运行bundle install.以下是我的追踪:

Installing rmagick (2.13.2)

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

brew医生输出

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:

    /usr/local/bin/gpg-error-config
    /usr/local/bin/ksba-config
    /usr/local/bin/pkg-config

Warning: Your Homebrew is not installed to /usr/local
You can install Homebrew anywhere you want, but some brews may only build
correctly if you install in /usr/local. Sorry!

Warning: You have a non-Homebrew 'pkg-config' in your PATH:
  /usr/local/bin/pkg-config

`./configure` may have problems finding brew-installed packages using
this other pkg-config.

@isea和我在聊天中经历了这个.关键问题是:

1. Homebrew安装在非标准位置.作为一般规则,那是危险的.
2. 卸载并重新安装Homebrew后,需要使用'brew install pkg-config'安装pkg-config软件包

这解决了这个问题.
