Mac通过Brew来安装Python，使用Brew Doctor检查出现关于./configure的问题，解决方法：

问题描述：

 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:


    /Library/Frameworks/Python.framework/Versions/2.7/bin/python-config

    /Library/Frameworks/Python.framework/Versions/2.7/bin/python2-config

    /Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7-config

解决方法：

sudo rm -rf /Library/Frameworks/Python.framework
