在MacOS下Python安装lxml报错xmlversion.h not found 报错的解决方案
最近在看一个自动化测试框架的问题,需要用到Lxml库,下载lxml总是报错。
1,使用pip安装lxml
pip install lxml
2,然后报错了,报错内容是:
In file included from src/lxml/lxml.etree.c:139:src/lxml/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----------------------------------------Cleaning up...Command /usr/bin/python -c "import setuptools, tokenize;__file__=‘/private/var/folders/rc/0lpvj1710n332qg8p2wgcqyr0000gn/T/pip_build_cindy_mac/lxml/setup.py‘;exec(compile(getattr(tokenize, ‘open‘, open)(__file__).read().replace(‘\r\n‘, ‘\n‘), __file__, ‘exec‘))" install --record /var/folders/rc/0lpvj1710n332qg8p2wgcqyr0000gn/T/pip-xwdVzY-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /private/var/folders/rc/0lpvj1710n332qg8p2wgcqyr0000gn/T/pip_build_cindy_mac/lxmlStoring debug log for failure in /Users/cindy_mac/Library/Logs/pip.log
3,然后百度了N久N久,借鉴了一个大神的方案,http://blog.marchtea.com/archives/91
4,找到进入Application->XCode,右键选择:显示内容,按照下面代码的路径一步一步往下跟:复制路径:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include
然后在终端输入:
C_INCLUDE_PATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2/libxml:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include
5,然后再次使用pip安装
pip install lxml
6,看到成功了!!!我眼泪留下来。。。

7,为了保险,然后测试一下:

没有报错,我就很开心
