在amazon ec2上的python34中安装lxml

Question

我在这个主题上看过很多线程，但我仍然无法在Amazon EC2上的python34中安装lxml模块。

我已经安装了请求模块

sudo easy_install-3.4 requests

但是，如果我尝试安装lxml模块

sudo easy_install-3.4 lxml

它失败了，我得到了

Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?

那么我尝试用以下命令安装libxml2：

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

我明白了

Nothing to do

那么如果已经安装了libxml2模块，问题出在哪里呢？

Answer 1

根据以下错误消息，它看起来不像您安装了编译器。

/usr/lib64 unable to execute 'gcc': No such file or directory

除了开发库之外，您还需要安装编译器。

sudo yum install gcc libxml2-devel libxslt-devel python-devel
sudo easy_install-3.4 lxml
