解决python 缺少　＇python.

最近用pip安装工具包老是出现错误

错误如下：

In file included from greenlet.c:5:0:

greenlet.h:8:20: 致命错误： Python.h：没有那个文件或目录

编译中断。

error: Setup script exited with error: command 'gcc' failed with exit status 1 

解决方法是安装python-dev，这是Python的头文件和静态库包:

ubuntu　下安装

sudo apt-get install python-dev

Centos 下安装

yum install python-devel
