LXML安装失败在Ubuntu 14.04

Question

我试图安装lxml Python模块：

sudo pip3 install lxml 

以前我用：

sudo apt-get install libxml2-dev libxslt1-dev python-dev 

我得到这个输出（几分钟挂起之前失败） - 结束于：

在本地机器上安装成功，在VPS上失败。

Answer 1

This answer工作对我来说：

sudo apt-get install -y libxml2-dev libxslt1-dev zlib1g-dev python3-pip 
sudo pip install lxml 

Answer 2

转到http://www.lfd.uci.edu/~gohlke/pythonlibs/。这是一切安全的保证。只需进入LXML部分，然后为您的机器和Python类型选择正确的whl文件（它们具有32位和64位，Python 2.6到最新，甚至是beta 3.5！）。点安装轮子，你就完成了。
