我正在尝试安装lxml python模块：
sudo pip3 install lxml
以前我用过：
sudo apt-get install libxml2-dev libxslt1-dev python-dev
我得到了这个输出（失败前挂起几分钟）-结束：

Cleaning up...
Command /usr/bin/python3 -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/lxml/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('rn', 'n'), __file__, 'exec'))" install --record /tmp/pip-67svy8ob-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_root/lxml

在本地计算机上成功安装，在VPS上失败。
这个答案对我有效：
sudo apt-get install -y libxml2-dev libxslt1-dev zlib1g-dev python3-pip
sudo pip install lxml
转到http://www.lfd.uci.edu/~gohlke/pythonlibs/。这是一个一次性安装的一切，保证。只需转到LXML部分，为您的机器和Python类型选择正确的whl文件（它们有32位和64位，Python 2.6到最新版本，甚至beta 3.5！）。
