Question

我在lxml上安装CentOS-6时遇到问题。我尝试过一些类似问题的解决方案，例如pip install lxml error或Setup.py: install lxml with Python2.6 on CentOS，但这些问题无效。如何正确安装？发布后，

pip install lxml

日志就是这样，

我在Python 2.6.6上使用CentOS release 6.5。

在新环境设置/包安装过程中，可能遇到的最常见问题如下：

gcc - 构建C软件包需要Python编译器，核心为C。

$sudo yum install gcc
'错误：命令'gcc'失败并退出状态1 '当找不到头文件（#include）时发生，即未安装依赖项

解决方案：安装系统级依赖项（开发包）

$sudo yum install libxml2-devel libxml++-devel libxslt-devel
虽然在您的情况下，“ gcc：内部错误：已杀死（程序cc1）”不能是上述可能性，依赖性存在，因为没有“未找到”任何缺少的头文件或任何其他语法级别错误的错误。发生了什么（可能），gcc编译器崩溃了。存在相当大的可能性是内存问题，即内存不足。

虽然您没有提到是否已设置VM或本机安装 - 通常我们在设置VM时分配有限的内存。如果您正在使用VM，可能的方法是增加CentOS VM的已分配内存，或通过关闭任何不必要的运行程序和服务来释放一些内存。

P.S。我在安装lxml时遇到了同样的问题，并用更多内存解决了它。
