python - 错误pyodbc用python连接sql server

Question

我正在尝试从 sqlserver 自动迁移到 postgres，所以我尝试使用 pyodbc 然后安装了它

pip install pyodbc 

在我尝试使用以下代码与 python 建立连接之后:

import pyodbc

cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=192.168.0.12;DATABASE=Aval;UID=sa;PWD=1032')
cursor = cnxn.cursor()
cursor.execute("select * from user")
rows = cursor.fetchall()
for row in rows:
    print row.user_id, row.user_name

当我尝试运行它时出现以下错误:

Traceback (most recent call last):
  File "migracion.py", line 1, in <module>
    import pyodbc
ImportError: dlopen(/usr/local/lib/python2.7/site-packages/pyodbc.so, 2): Library not loaded: /usr/local/lib/libodbc.2.dylib
  Referenced from: /usr/local/lib/python2.7/site-packages/pyodbc.so
  Reason: image not found

环境信息:

• SO: Mac 优胜美地
• python版本:2.7.10
• pip 版本:来自/usr/local/lib/python2.7/site-packages (python 2.7) 的 pip 7.1.0

你需要安装正确的odbc

对于 mysql brew install mysql-connector-odbc 和对于 postgres brew install psqlodbc
