pypyodbc 过去曾为我工作，但由于某种原因它不起作用。我在 ~/.odbc.ini 中定义了这个

[as400]

Trace                   = 0

并且可以与$ isql as400.

但是使用以下程序：

import pypyodbc

conn = pypyodbc.connect("Driver={as400};System=mysystem;Uid=myuser;Pwd=mypass;")

我收到此错误：

Traceback (most recent call last):
  File "dbtest.py", line 3, in <module>
    conn = pypyodbc.connect("Driver={as400};System=mysystem;Uid=myuser;Pwd=mypass;")
  File "/home/wwerner/.virtualenvs/devtools/lib/python3.4/site-packages/pypyodbc.py", line 2435, in __init__
    self.connect(connectString, autocommit, ansi, timeout, unicode_results, readonly)
  File "/home/wwerner/.virtualenvs/devtools/lib/python3.4/site-packages/pypyodbc.py", line 2484, in connect
    check_success(self, ret)
  File "/home/wwerner/.virtualenvs/devtools/lib/python3.4/site-packages/pypyodbc.py", line 988, in check_success
    ctrl_err(SQL_HANDLE_DBC, ODBC_obj.dbc_h, ret, ODBC_obj.ansi)
  File "/home/wwerner/.virtualenvs/devtools/lib/python3.4/site-packages/pypyodbc.py", line 964, in ctrl_err
    raise Error(state,err_text)
pypyodbc.Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified')

我尝试在 pypyodbc 源中寻找某种方式来反映这种isql -v能力，但VERBOSE = True不是这样。我还发现了一个错误，显然它过去只是发送第一封信，我想也许不知何故我遇到了这个问题，但我不知道在哪里可以找到它。

我怎样才能让它再次工作？

您的 Python 脚本失败，因为“as400”是您创建的 ODBC DSN的名称，因此您需要在连接字符串中使用DSN=as400而不是。Driver={as400}
