Question

尝试在Mac OS X 10.6.6上构建任何版本的pymssql。版本1.0.2（稳定）和1.9.909（主干）都构建和安装，但在导入时返回以下错误。有没有人在这个项目上取得成功？（注意我在此期间使用 pyodbc ，但是如果可能的话，想要消除ODBC层）

Python 2.6.5 (r265:79359, Mar 24 2010, 01:32:55)

Answer 1

fab（fabric）脚本我写的是为了做到这一点

import os
from fabric.api import local

def prep_dev_env():
    os.chdir('/tmp/')
    local('cvs -d:pserver:freetds.cvs.sourceforge.net:/cvsroot/freetds login')
    local('cvs -z3 -d:pserver:freetds.cvs.sourceforge.net:/cvsroot/freetds checkout -P freetds')
    os.chdir('/tmp/freetds/')
    local('sudo ./autogen.sh --with-tdsver=7.0')
    local('sudo make')
    local('sudo make install')
    os.chdir('/tmp/')
    #assumes macports is installed
    local('sudo port install mercurial')
    local('hg clone https://code.google.com/p/pymssql/')
    os.chdir('/tmp/pymssql/')
    local('python setup.py config')
    local('python setup.py build')
    local('python setup.py install')
    return

Answer 2

使用tdsver 7.2，请参阅here

在我的虚拟环境中：

pip install cython >> ok
vim `locate Formula/freetds.rb`
#:s:7.1:8.0:g # Change version 7.1 to 8.0...
#:wq
cd /tmp
wget http://pypi.python.org/packages/source/p/pymssql/pymssql-1.0.2.tar.gz#md5=04dc4aa591acacbc8f183daeea21b690
tar -xzvf pymssql-1.0.2.tar.gz
cd pymssql-1.0.2
python setup.py config
python setup.py build
sudo python setup.py install

最后，成功！
