编译中断。

出现这个问题的原因是，系统中的python是自带的，而没有安装python的开发包并没有安装，

所以在shell下执行如下命令：

$ sudo apt-get install python-dev

$ sudo easy_install sqlalchemy

缷载easy_install安装的包

（个人感觉easy_install没有pip方便，推荐大家使用pip安装和缷载https://pypi.python.org/pypi/pip）

如何缷载esay_install安装的sqlalchemy呢，这里是官方文档：

Because this distribution was installed --multi-version, before you can
import modules from this package in an application, you will need to
'import pkg_resources' and then use a 'require()' call similar to one of
these examples, in order to select the desired version:

    pkg_resources.require("SQLAlchemy")  # latest installed version
    pkg_resources.require("SQLAlchemy==0.9.8")  # this exact version
    pkg_resources.require("SQLAlchemy>=0.9.8")  # this version or higher
