我如何在Amazon EC2 linux上安装lxml依赖项？

我试过了：

sudo yum install libxml2-dev libxslt-dev python-dev

我得到了：

Loaded plugins: priorities,update-motd,upgrade-helper amzn-main/latest | 2.1 kB 00:00 amzn-updates/latest | 2.3 kB 00:00 No package libxml2-dev available. No package libxslt-dev available. No package python-dev available.

点也没有工作。

我得到了这样的包：

Apache 502错误 – 服务器挂断

在Amazon EC2 Windows 2008映像上运行Win32可执行文件

在Amazon EC2中创build子域

Amazon EC2区域和Windows Azure关联组 – 安全注意事项

SSH到AWS EC2问题 – key_load_public：没有这样的文件或目录

git clone --branch lxml-3.2.4 https://github.com/lxml/lxml

然后我尝试没有cython，因为sudo python setup.py install给了我RuntimeError: ERROR: Trying to build without Cython,but pre-generated 'src/lxml/lxml.etree.c' is not available

sudo python setup.py install --without-cython

然后我得到：

sudo python setup.py install --without-cython Building lxml version 3.2.4. WARNING: Trying to build without Cython,but pre-generated 'src/lxml/lxml.etree.c' is not available. WARNING: Trying to build without Cython,but pre-generated 'src/lxml/lxml.objectify.c' is not available. Building without Cython.

它真的希望我确保安装了libxml2和libxslt的开发包 。

如果我能做到这一点，我希望它能工作。 有任何想法吗？ 谢谢！ 看来人们对此有相关的问题，但大多数都在其他系统上。

更新：基于Vor的build议，我使用了-devel扩展，并且工作来安装依赖关系。

sudo yum install libxml2-devel libxslt-devel python-devel

不幸的是我得到这个：

AWS ec2 en_US.UTF-8问题

我有同样的问题。 在这行之后：

sudo yum install libxml2-devel libxslt-devel python-devel

我再次尝试

sudo yum install lxml

它的工作:)

sudo yum install libxml2-devel libxslt-devel python-devel

加

sudo yum install gcc

这对我有用。

在CentOS上是python-devel ，而不是python-dev 。 和其他人一样。

在这个过程中破坏了构建中间文件。 试试rm -rf / tmp / pip-build-root

以下为我工作：

sudo yum install libxml2-devel libxslt-devel python-devel

在AWS EC2实例上：

Amazon Linux AMI release 2015.09

在我的AWS机器上，我同时安装了python2.7和python3.4，而且我正在为python3.4安装lxml – 我发现我必须使用

sudo yum install python34-devel

EC2 t.micro上的问题是，你用尽了内存来编译lxml包。

当你运行：dmesg | 尾巴你会看到这个问题

内存不足：杀死进程9804（cc1）得分499或牺牲子女[167588.475046]杀死进程9804（cc1）total-vm：693864kB，anon-RSS：521696kB，file-RSS：0kB

唯一的方法是通过yum或其他包管理器来安装python-lxml包。

加上huapito的答案。 以下代码为我工作。 sudo yum install gcc libxml2-devel libxslt-devel python-devel sudo pip install lxml
