LXML安裝失敗在Ubuntu 14.04

Question

我試圖安裝lxml Python模塊：

sudo pip3 install lxml 

以前我用：

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

我得到這個輸出（幾分鐘掛起之前失敗） - 結束於：

在本地機器上安裝成功，在VPS上失敗。

Answer 1

This answer工作對我來說：

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

Answer 2

轉到http://www.lfd.uci.edu/~gohlke/pythonlibs/。這是一切安全的保證。只需進入LXML部分，然後爲您的機器和Python類型選擇正確的whl文件（它們具有32位和64位，Python 2.6到最新，甚至是beta 3.5！）。點安裝輪子，你就完成了。
