未能在MacOS中安裝lxml 10.8.4

Question

我在安裝lxml到我的Mac OS時遇到問題。 構建它時出現以下錯誤。

brew install libxml2 
brew link libxml2 --force 

我是新至Mac：使用pip install lxml

/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

我已經安裝的libxml2與沖泡時，這是我的錯誤。在Ubuntu中，這意味着必須安裝libxml2-dev軟件包。

更新：這裏是pip.log：

"~/.pip/pip.log" 124L, 8293C requirement_set.install(install_options, global_options, root=options.root_path) File "/usr/local/Cellar/python/2.7.5/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip-1.3.1-py2.7.egg/pip/req.py", line 1185, in install requirement.install(install_options, global_options, *args, **kwargs) File "/usr/local/Cellar/python/2.7.5/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip-1.3.1-py2.7.egg/pip/req.py", line 592, in install cwd=self.source_dir, filter_stdout=self._filter_install, show_stdout=False) File "/usr/local/Cellar/python/2.7.5/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip-1.3.1-py2.7.egg/pip/util.py", line 662, in call_subprocess % (command_desc, proc.returncode, cwd)) InstallationError: Command /usr/local/Cellar/python/2.7.5/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python -c "import setuptools;file='/private/var/folders/9s/s5hl5w4x7zjdjkdljw9cnsrm0000gn/T/pip-build-khuevu/lxml/setup.py';exec(compile(open(file).read().replace('\r\n', '\n'), file, 'exec'))" install --record /var/folders/9s/s5hl5w4x7zjdjkdljw9cnsrm0000gn/T/pip-nsV0iT-record/install-record.txt --single-version-externally-managed failed with error code 1 in /private/var/folders/9s/s5hl5w4x7zjdjkdljw9cnsrm0000gn/T/pip-build-khuevu/lxml

任何想法？ 非常感謝

Answer 1

轉出xmlversion.h不包含在編譯路徑中，即使它在PATH中。修改C_INCLUDE_PATH ENV修復錯誤對我來說：

C_INCLUDE_PATH=/usr/local/Cellar/libxml2/2.9.1/include/libxml2:$C_INCLUDE_PATH

Answer 2

如果您正在運行安裝了Xcode的小牛，你也可以使用：

export C_INCLUDE_PATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/usr/include/libxml2:$C_INCLUDE_PATH 

Answer 3

brew install libxml2 
brew link libxml2 --force 
export C_INCLUDE_PATH=/usr/local/Cellar/libxml2/2.9.2/include/libxml2:$C_INCLUDE_PATH 

Answer 4

其他的答案無（出口C_INCLUDE_PATH）爲我工作。但是，將CFLAGS環境變量設置爲內置OS X 10.10 libxml2 root就像一個魅力一樣。

export CFLAGS=-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2 

Answer 5

我已經Python和libxml的通過釀造安裝，這個工作對我來說嘗試上述一切後：

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：您需要檢查自己的路徑，最新版本。

由於頭文件在其他地方可用，並在特定的目錄中查找（發現在命令中調用clang進行編譯） - 由於某種原因沒有選擇替代位置，我在右邊做了一個軟鏈接地點。

Answer 6

當系統是Mac EI隊長時，有mkdir的/usr/權限。也許我們不能修改這個目錄？
