Pip Install lxml

2, and then error, the error content is:

3, then Baidu has n long N long, borrowed from a great God's plan, http://blog.marchtea.com/archives/91

4, find into Application->xcode, right-click: display Content , follow the following code path step by step: Copy path:/applications/xcode.app/contents/ Developer/platforms/macosx.platform/developer/sdks/macosx10.9.sdk/usr/include

Then enter in the terminal:

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, then use PIP to install again

Pip Install lxml

6, see the Success!!!
