$ sudo easy_install sqlalchemy [sudo] password for ovonel: Searching for sqlalchemy Reading http://pypi.python.org/simple/sqlalchemy/ Best match: SQLAlchemy 0.9.8 Downloading https://pypi.python.org/packages/source/S/SQLAlchemy/SQLAlchemy-0.9.8.tar.gz#md5=470ca4da4a0081efc830f0d90dd91682 Processing SQLAlchemy-0.9.8.tar.gz Running SQLAlchemy-0.9.8/setup.py -q bdist_egg --dist-dir /tmp/easy_install-niIczD/SQLAlchemy-0.9.8/egg-dist-tmp-K7Kb1x warning: no files found matching '*.jpg' under directory 'doc' warning: no files found matching 'distribute_setup.py' warning: no files found matching 'sa2to3.py' warning: no files found matching 'ez_setup.py' no previously-included directories found matching 'doc/build/output' lib/sqlalchemy/cextension/processors.c:10:20: 致命错误： Python.h：没有那个文件或目录 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 Searching for sqlalchemy Reading http://pypi.python.org/simple/sqlalchemy/ Best match: SQLAlchemy 0.9.8 Downloading https://pypi.python.org/packages/source/S/SQLAlchemy/SQLAlchemy-0.9.8.tar.gz#md5=470ca4da4a0081efc830f0d90dd91682 Processing SQLAlchemy-0.9.8.tar.gz Running SQLAlchemy-0.9.8/setup.py -q bdist_egg --dist-dir /tmp/easy_install-Nu0lzS/SQLAlchemy-0.9.8/egg-dist-tmp-R1tVSz warning: no files found matching '*.jpg' under directory 'doc' warning: no files found matching 'distribute_setup.py' warning: no files found matching 'sa2to3.py' warning: no files found matching 'ez_setup.py' no previously-included directories found matching 'doc/build/output' zip_safe flag not set; analyzing archive contents... sqlalchemy.testing.plugin.noseplugin: module references __file__ Adding SQLAlchemy 0.9.8 to easy-install.pth file Installed /usr/local/lib/python2.7/dist-packages/SQLAlchemy-0.9.8-py2.7-linux-x86_64.egg Processing dependencies for sqlalchemy Finished processing dependencies for 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：
