Fail to install lxml in MacOS 10.8.4
我在将lxml安装到Mac OS时遇到问题。
构建它时出现以下错误。 这是使用
/private/var/folders/9s/s5hl5w4x7zjdjkdljw9cnsrm0000gn/T/pip-build-khuevu/lxml/src/lxml/includes/etree_defs.h:9:10: fatal error: 'libxml/xmlversion.h' file not found
我用brew安装了libxml2：
1 2 | brew install libxml2 brew link libxml2 --force |
我是Mac的新手。 在Ubuntu中，这意味着必须安装libxml2-dev软件包。
更新：这是pip.log：

任何的想法 ？
非常感谢
结果xmlversion.h不包含在编译路径中，即使它在PATH中。修改C_INCLUDE_PATH env为我修复错误：
C_INCLUDE_PATH=/usr/local/Cellar/libxml2/2.9.1/include/libxml2:$C_INCLUDE_PATH
如果您在安装Xcode的情况下运行Mavericks，您还可以使用：
1 | export C_INCLUDE_PATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/usr/include/libxml2:$C_INCLUDE_PATH |
我通过brew安装了Python和libxml，在尝试了以上所有内容后，这对我有用：
1 2 | sudo mkdir /usr/include # If /usr/include is missing sudo ln -s /usr/local/Cellar/libxml2/2.9.2/include/libxml2 /usr/include/libxml2 |
注意：您需要检查自己的路径以获取最新版本。
由于标题在别处可用，并且在特定目录中查找(在命令调用clang编译中发现) - 由于某种原因，备用位置没有被拾取，我做了一个到正确位置的软链接。
没有其他答案(导出C_INCLUDE_PATH)对我有用。但是，将CFLAGS环境变量设置为内置OS X 10.10 libxml2根就像魅力一样。
1 | export CFLAGS=-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2 |
1 2 3 | brew install libxml2 brew link libxml2 --force export C_INCLUDE_PATH=/usr/local/Cellar/libxml2/2.9.2/include/libxml2:$C_INCLUDE_PATH |
