CentOS7安装Murano-agent时的error:command 'gcc' failed with exit status 1

在build  Symphony 的CentOS image的时候，需要安装Murano-agent，

git clone 下来Murano-agent的包以后，先执行以下命令安装依赖

pip install -r requirement.txt

这个时候出现了这个错误：

In file included from greenlet.c:5:0:
greenlet.h:8:20: fatal error: Python.h: No such file or directory
compilation terminated.
error: Setup script exited with error: command 'gcc' failed with exit status 1`

这是因为没有安装Python development 需要的headers导致的

可以做如下处理

yum install python-devel

yum install libevent-devel

就可以解决这个问题了
