我pyodbc上班很麻烦 我有unixodbc，unixodbc-dev，odbc- postgresql，pyodbc安装在我的Linux Mint的14。我的包我失去希望找到我自己的解决方案，任何帮助表示赞赏。请参阅以下详细信息：

运行：

>>> import pyodbc
>>> conn = pyodbc.connect("DRIVER={PostgreSQL};SERVER=localhost;DATABASE=test;USER=openerp;OPTION=3;")

给我：

>>> pyodbc.Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnect)')

＃odbcinst -j给出 ：

unixODBC 2.2.14
DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
FILE DATA SOURCES..: /etc/ODBCDataSources
USER DATA SOURCES..: /home/atman/.odbc.ini
SQLULEN Size.......: 4
SQLLEN Size........: 4
SQLSETPOSIROW Size.: 2

这使我认为存在unixodbc配置问题。这是我的unixodbc配置文件内容：

档案 /etc/odbcinst.ini ：
