macos上安装mysqldb，EnvironmentError:mysql

$ 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 /Library/Python/2.7/site-packages/MySQL_python-1.2.3-py2.7-m

$ 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
/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

>>> conn=MySQLdb.connect(host="localhost",user="root",passwd="root",db="mysql")
>>> cursor =conn.cursor()

能够读取mysql.user表的信息了，说明已经mysqldb已经安装成功。

或者修改bash_profile文件

PATH="/usr/local/mysql/bin:${PATH}"
export PATH
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
export VERSIONER_PYTHON_PREFER_64_BIT=yes
export VERSIONER_PYTHON_PREFER_32_BIT=no
