我在以非root用户身份登录时在virtualenv中安装lxml和scrapy时遇到问题。以root用户身份登录时，安装对于相同的环境可以正常工作。
我遵循的步骤如下：
以非root用户身份登录
virtualenv -p python3 test
cd test
source bin/activate
pip install lxml

to CFFI but generic to the setup.py of any Python package that
tries to compile C code. (Hints: on OS/X 10.8, for errors about
-mno-fused-madd see http://stackoverflow.com/questions/22313407/
