pip安装lxml库，试了很多次，都会卡在这里：
用top命令查看系统资源，发现物理内存基本耗尽，但是虚拟内存没怎么用：

After finding a machine with the same version and installing it, copy the lxml under site-package and you can use it^_^The premise is that the target machine has libxml2, libxslt, libxml2-devel, libxslt installed -devel.
I don’t know what your specific problem is. Here are my installation steps:
apt-get install libxml2-dev, libxslt1-dev, python-dev pip install lxml
lxml installation takes a long time, more than 10 minutes, it is recommended to wait longer.
