and I got:

pip did not work either.
pip也不起作用。
I got the package like this:
我收到的包裹是这样的:
git clone --branch lxml-3.2.4 https://github.com/lxml/lxml
Then I tried without cython because sudo python setup.py install gave me RuntimeError: ERROR: Trying to build without Cython, but pre-generated 'src/lxml/lxml.etree.c' is not available
然后我尝试不使用cython，因为sudo python设置。py安装给了我运行时错误:错误:试图在没有Cython的情况下构建，但是预先生成了“src/lxml/lxml.etree”。c '是不可用的
sudo python setup.py install --without-cython
Then I got:

It really wants me to make sure the development packages of libxml2 and libxslt are installed.
它确实希望我确保安装了libxml2和libxslt的开发包。
If I can do that I hope it will work. Any ideas? Thanks! It seems people have related issues to this, but most are on other systems.
如果我能做到，我希望它能起作用。什么好主意吗?谢谢!似乎人们对此有相关的问题，但大多数都在其他系统上。
UPDATE: Based on Vor's suggestion I used the -devel extension and that worked to install the dependencies.
更新:基于Vor的建议，我使用了-devel扩展，并使用它来安装依赖项。
sudo yum install libxml2-devel libxslt-devel python-devel
Unfortunately I get this:

The problem on EC2 t.micro is that you run out of memory to compile the lxml package.
EC2 t上的问题。micro就是你用完内存来编译lxml包。
When you run: dmesg | tail you will see the issue
当您运行:dmesg |尾部时，您将看到问题
