我在anaconda env中使用pip尝试安装需要GDAL或lxml的框架和软件包时遇到了持续的问题。我正在使用Anaconda安装的Python 2.7.5运行OSX 10.8。我已经安装了命令行工具Xcode 4.6.3。
在需要lxml或GDAL的软件包上（几乎每个GIS软件包）我都会遇到clang错误。这些通常是错误1或错误254.我安装了GDAL框架并且（显然）与QGIS一起运行（虽然这指的是系统python而不是Anaconda发行版）。我有Anaconda提供的lxml，它似乎在env中用于编写脚本。我试过更新lxml，没效果。本问题末尾包含两个示例日志。抱歉这个问题有点长......
通常重复的建议似乎是获得Xcode和CLT。正如我所说，我已经做到了。
我在网上看到的另一个想法与用于构建OSX的Anaconda Python发行版的C编译器有关。我对C编译器一无所知，但我知道pip将软件包安装到系统python中没有问题。当我启动系统Python时，我得到：
Python 2.7.2 (default, Oct 11 2012, 20:14:37)
[GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
对于Anaconda Python，我得到：
Python 2.7.5 |Anaconda 1.6.1 (x86_64)| (default, Jun 28 2013, 22:20:13)
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin

注意GCC版本的差异。这有意义吗？
最近pip尝试安装kartograph.py失败了。在我的环境中运行pip install -r https://raw.github.com/kartograph/kartograph.py/master/requirements.txt后，我很快就遇到了麻烦

非常感谢帮助。我一直在Anaconda工作以获得其他应用程序，并希望继续使用此发行版。

这是我的0.02美元，根据我的经验，OS X上的lxml安装总是因为libmxl2和libxslt依赖而导致问题。这里的具体问题是找不到'cpl_port.h'，表明你的系统上没有gdal的头文件，这与我在lxml上遇到的问题类似。我发现这个StackExchange帖子gdal package missing使用pip和虚拟Ubuntu机器来解决使用你的特定错误构建和安装gdal的问题，但这个想法是一样的。需要明确告知pip工具在哪里找到gdal的头文件。
一般来说，问题是OS X将标头放在* nix系统的非标准位置，并且通常依赖关系是用于开发您尝试安装的软件包的版本背后的几个版本。您可以使用MacPorts或类似的东西，它们将搭载OS X，为所有依赖项创建类似于Linux的结构，使用更多当前版本的库，但虚拟化程度非常好，很少有运行OS XI的生产系统感觉更简单解。我是一个15年以上的Apple用户，但是当谈到Mac上的Python开发时，我的建议是使用某种虚拟化工具，我真的很喜欢Vagrant和VirtualBox。除非您要在OS X或OS X Server上生成Python代码，否则最好在最终生产操作系统上进行开发，以便在开发期间了解可用的依赖性版本以及存在特定于环境的效果。再加上几乎任何其他操作系统都比安装OS X更容易安装像lxml和gdal这样的软件包，在Debian变种上使用简单的“sudo apt-get install -y --fix-missing”可以获得缺少的依赖关系并继续前进。 Vagrant甚至会将您的源文件从主机同步到guest虚拟机，这样您就可以毫不费力地使用富客户端IDE。

在终端中使用conda install gdal，这将提取并安装gdal库
