家庭酿造失败的“​​命令”gcc'失败，退出状态1“错误

Question

我想开始使用geodjango，为此我必须安装gdal。我使用的MacOS 10.8.3 为了与酿造这样做的GeoDjango内置文档中的建议，但我得到了以下错误：

$brew install gdal 
==> Downloading http://download.osgeo.org/gdal/1.10.0/gdal-1.10.0.tar.gz

Your Xcode and or CLT are mis-configured. Try some or all of the following: 
    xcodebuild -license 
    sudo xcode-select -switch /path/to/Xcode.app 
error: command 'gcc-4.2' failed with exit status 1

These open issues may also help:

    https://github.com/mxcl/homebrew/issues/20373 
    https://github.com/mxcl/homebrew/pull/20457 

诚如，我所做的：

xcodebuild -license 

，并同意然后：

sudo xcode-select -switch /Applications/Xcode.app 

我也检查了问题，但没有一个是有用的。

我已经安装了Xcode 4.6.3，并在过去酿造了许多其他配方，没有任何问题。

当我运行冲泡医生，我得到：

$brew doctor 
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 
    /Applications/Postgres.app/Contents/MacOS/bin/gdal-config 
    /Applications/Postgres.app/Contents/MacOS/bin/geos-config 
    /Applications/Postgres.app/Contents/MacOS/bin/uuid-config 
    /Applications/Postgres.app/Contents/MacOS/bin/xml2-config 

我不想在我的道路删除postgres.app，因为它是必要的postgres.app配置的CLI如下解释：http://postgresapp.com/documentation#toc_1

关于从库中的蟒蛇，我试图删除它们使用：

PATH=$(echo $PATH |sed 's/\/Library\/Frameworks\/Python.framework\/Versions\/2.7\/bin//') 

的建议在这里：https://www.linuxquestions.org/questions/linux-newbie-8/how-to-remove-directory-from-%24path-483463/。但它并没有从路径中移除任何东西。

所以在这里我不打算安装@中......

我找到了一个解决办法的话，我无法找到原来的职位，但类似的信息都在这一个给定的：Installing Scipy on Mac OS X Lion 10.7.5

所以我添加下面几行到我的.bashrc，然后我设法创建安装gdal。

export CC=gcc 
export CXX=g++ 

要知道，这并没有解决我的问题完全是因为我仍然有配置问题与GeoDjango内置，但至少我已经安装@中。
