Question

在亚马逊ec2实例上安装lxml时遇到问题。

你能帮我搞清楚吗？我认为基于wordsize.h问题安装gcc的方式可能有问题，但我不知道。

非常感谢任何帮助。

Answer 1

看起来它没有找到特定于平台的包含文件。即bits / wordsize.h

检查您是否有以下目录：

/usr/include/x86_64-linux-gnu/bits

如果存在，请尝试以下

cd /usr/include
ln -s /usr/include/x86_64-linux-gnu/* .

如果文件不存在，请尝试：

sudo apt-get install libc6-dev

如果您使用的是CentOS或Redhat

yum install glibc-devel glibc-headers

Answer 2

如果您尝试在Python 3 virtualenv中安装lxml，则需要安装python34-devel而不仅仅是python-devel：

sudo yum install python34-devel

在ec2上安装lxml时出错
