You need to install Python's header files (python-dev package in debian/ubuntu) to compile lxml. As well as libxml2, libxslt, libxml2-dev, and libxslt-dev:
编译lxml需要安装Python的头文件（debian/ubuntu中的python-dev包）。除了 libxml2、libxslt、libxml2-dev 和 libxslt-dev：
apt-get install python-dev libxml2 libxml2-dev libxslt-dev

Just do:
做就是了：
sudo apt-get install python-lxml
For Python 2 (e.g., required by Inkscape):
对于 Python 2（例如，Inkscape 需要）：
sudo apt-get install python2-lxml
If you are planning to install from source, then albertov's answerwill help. But unless there is a reason, don't, just install it from the repository.
如果您打算从源代码安装，那么albertov 的回答会有所帮助。但是除非有原因，否则不要从存储库中安装它。

For RHEL/CentOS, run "python --version" command to find out Python version. E.g. below:
对于 RHEL/CentOS，运行“python --version”命令来查找 Python 版本。例如下面：
$ python --version
Python 2.7.12
Now run "sudo yum search lxml" to find out python*-lxml package.
现在运行“sudo yum search lxml”来找出 python*-lxml 包。
$ sudo yum search lxml

python26-lxml.x86_64 : ElementTree-like Python bindings for libxml2 and libxslt
python27-lxml.x86_64 : ElementTree-like Python bindings for libxml2 and libxslt
Now you can choose package as per your Python version and run command like below:
现在您可以根据您的 Python 版本选择包并运行如下命令：
$ sudo yum install python27-lxml.x86_64
