下載MySQL-python-1.2.3.tar.gz
進入到MySQL-python目錄運行 python setup.py install 出現錯誤。
因爲要使用setup.py需要安裝python-setuptools
下面是setuptools安裝:
· 下載 http://peak.telecommunity.com/dist/ez_setup.py
· 運行 python ez_setup.py
再一次進入到MySQL-python目錄運行python setup.py install
再次出現錯誤:
sh: mysql_config: not found Traceback (most recent call last): File "setup.py", line 15, in <module> metadata, options = get_config() File "/root/MySQL-python-1.2.3/setup_posix.py", line 43, in get_config libs = mysql_config("libs_r") File "/root/MySQL-python-1.2.3/setup_posix.py", line 24, in mysql_config raise EnvironmentError("%s not found" % (mysql_config.path,)) EnvironmentError: mysql_config not found
用find / -name mysql_config命令在系統裏查找mysql_config,
結果爲空,原因是libmysqlclient-dev庫沒有裝上。
於是 apt-get install libmysqlclient-dev
再查詢一次mysql_config文件,
可以得到該文件的地址,我這裏是/usr/bin/mysql_config
編輯site.cfg文件,修改mysql_config變量爲上面的地址:
mysql_config = /usr/bin/mysql_config
然後再運行python setup.py install,
又提示錯誤:
In file included from _mysql.c:29: pymemcompat.h:10:20: error: Python.h: No such file or directory _mysql.c:30:26: error: structmember.h: No such file or directory In file included from /usr/include/mysql/mysql.h:44, from _mysql.c:40: . . . _mysql.c:2808: warning: return type defaults to 'int' _mysql.c: In function 'DL_EXPORT': _mysql.c:2808: error: expected declaration specifiers before 'init_mysql' _mysql.c:2886: error: expected '{' at end of input error: command 'gcc' failed with exit status 1
經過google,這裏還需要裝python-dev庫,
果斷安裝之:
apt-get install python-dev
再一次python setup.py install,
終於成功裝上MySQLDB:

最後install:
sudo python setup.py install
搞定!

setuptools:
介紹setuptools,就要從distutils講起。Distutils屬於Python的標準庫,是從版本1.6以來就有的,其作用,主要是用來創建和使用安裝包,我們常見的setup.py就是基於這個工具集創建,並且被這個工具集所使用的。這個模塊的主要功能都在distutils.core裏面,作爲開發者,通常是導入distutils.core中的setup,來創建一個setup.py文件。
setuptools,則是在distutils基礎上的一個增強包,提高了創建分發包,使用分發包的能力。在這個增強的模塊裏面,新增加了easy_install.py,同時開始支持egg文件的構建和使用。對開發者來說,增加了MANIFEST,PyReg,PYPI等特性。
這裏,要提一下常用到的egg文件,egg文件,就像是java中的jar包,把代碼和資源打包起來成爲一個zip壓縮包,並且冠於egg後綴。
