Recently looking at an automated testing framework of the problem, need to use the lxml library, download lxml always error.

1, install lxml using 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

Install lxml

6, see the Success!!! I have tears to stay ...

7, for insurance, and then test it:

Without an error, I'd be happy.
