python – 无法使用pip安装lxml

sudo pip install lxml

我在清理阶段收到以下消息：

Cleaning up...
Command /usr/bin/python -c "import setuptools,tokenize;__file__='/private/tmp/pip_build_root/lxml/setup.py';exec(compile(getattr(tokenize,'open',open)(__file__).read().replace('rn','n'),__file__,'exec'))" install --record /tmp/pip-rUFjFN-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /private/tmp/pip_build_root/lxml
Storing debug log for failure in /Users/georgejor/Library/Logs/pip.log

在那之后,我得到了：

ImportError: No module named lxml

请帮忙.谢谢！

以下输出来自pip.log：
