mac os 上安装mysqldb,EnvironmentError: mysql_config not found

要在mac os上安装 mysqldb


首先,下载MySQLdb:http://sourceforge.net/projects/mysql-python/


下载MySQL-python-1.2.3.tar.gz

解压,运行setup.py:
python setup.py install
报错:
sh: mysql_config: command not found
Traceback (most recent call last):
File "setup.py", line 15, in <module>
metadata, options = get_config()
File "/Users/***/Downloads/MySQL-python-1.2.3/setup_posix.py", line 43, in get_config
libs = mysql_config("libs_r")
File "/Users/***/Downloads/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
参考:http://www.southsearepublic.org/article/2416/read/environmenterror_mysql_config_not_found/installing_mysqldb_for_python_on_mac_osx/
发现要修改site.cfg
mysql_config = /usr/local/mysql/bin/mysql_config
让mysql_config指向mysql在mac os中的安装位置。
之后再用高权限运行
sudo python setup.py install
如果运行的时候,还有问题:
>>> import MySQLdb
/Library/Python/2.7/site-packages/MySQL_python-1.2.3-py2.7-macosx-10.7-intel.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /Library/Python/2.7/site-packages/MySQL_python-1.2.3-py2.7-macosx-10.7-intel.egg/_mysql.pyc, but /Users/***/Downloads/MySQL-python-1.2.3
is being added to sys.path
Traceback (most recent call last):

Referenced from: /Users/***/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.7-intel.egg-tmp/_mysql.so
Reason: image not found
那么就需要解决动态引入的问题了(重新做一遍,并且设置环境变量):
$ sudo python setup.py clean
$ sudo python setup.py build
$ sudo python setup.py install
$ export
DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH

$python
>>> import MySQLdb

>>> conn=MySQLdb.connect(host="localhost",user="root",passwd="root",db="mysql")
>>> cursor =conn.cursor()
>>> sql ="select * from user"
>>> cursor.execute(sql)

>>> row=cursor.fetchone()
>>> print row
('localhost', 'root', '*81F5E21E35407D884A6CD4A731AEBFB6AF209E1B', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', '', '', '', '', 0L, 0L, 0L, 0L, '', '')
能够读取mysql.user表的信息了,说明已经mysqldb已经安装成功。

如果还是在eclipse中有问题,那就采用这里的办法http://yanghao.org/blog/archives/76
解决办法
eclipse->偏好设置->Pydev->Interpreter-Python->Environment里面增加下面内容,看图:


现在可以运行带有mysqldb的脚本了,不过还是有红叉,很不爽啊!!
