我正在尝试使用以下命令安装PIL(Python Imaging Library):
sudo pip install pil
但我收到以下消息:

--- using frameworks …我想安装Lxml,然后我可以安装Scrapy.
当我今天更新我的Mac时它不会让我重新安装lxml,我收到以下错误:
In file included from src/lxml/lxml.etree.c:314:
/private/tmp/pip_build_root/lxml/src/lxml/includes/etree_defs.h:9:10: fatal error: 'libxml/xmlversion.h' file not found
#include "libxml/xmlversion.h"
^
1 error generated.
error: command 'cc' failed with exit status 1
我已经尝试使用brew来安装libxml2和libxslt,两者都安装得很好但我仍然无法安装lxml.
上次我安装时我需要在Xcode上启用开发人员工具,但由于它更新到Xcode 5,它不再给我这个选项了.
有谁知道我需要做什么？

我有一个令人困惑的问题.我使用的是mac版本10.9,anaconda 3.4.1,python 2.7.6.
使用python-amazon-product-api开发Web应用程序.我克服了安装lxml的障碍,引用了clang错误:未知参数:' - mno-fused-madd'(python包安装失败).
但发生了另一个运行时错误 这是webbrowser的输出.
Exception Type: ImportError
Exception Value:
dlopen(/Users/User_Name/Documents/App_Name/lib/python2.7/site-packages/lxml/etree.so, 2): Library not loaded: libxml2.2.dylib
Referenced from: /Users/User_Name/Documents/App_Name/lib/python2.7/site-packages/lxml/etree.so
Reason: Incompatible library version: etree.so requires version 12.0.0 or later, but libxml2.2.dylib provides version 10.0.0
不确定如何继续并在此处和其他地方搜索此特定错误.任何帮助深表感谢!
像许多其他人一样,我在安装python库时遇到问题(下载为tar,然后提取).

谢谢你的帮助.
所以,我发现其他一些铿锵错误似乎有些类似,但是,修复不适用于我的情况.
我正在使用OSX Mavericks,我们正在尝试安装Ansible.我有点正确安装,但是当我尝试安装Ansible时,我得到了这个clang错误.我们首先想到它可能是一个版本问题,所以我在使用gcc49遇到同样的错误后重新安装了gcc46,但我仍然遇到错误.
有谁知道如何解决这一问题？
