错误的连接到Oracle从py2exe会的程序：无法获得Oracle环境下处理

Question

我python程序(Python2.6)的工作现在我运行，它使用的蟒蛇解释，它连接到Oracle数据库(10g XE)没有错误。然而，当我汇编使用py2exe，可执行的版本将失败的"无法获取Oracle环境下处理"在电话给您.connect().

我已经尝试过的以下有没有喜悦：

• Oracle即时客户10g和11g
• Oracle XE客户
• 重新安装您-5.0.2开始-10g。win32-py2.6.msi
• 设置 ORACLE_HOME 以及路径
• 另一个计算机仅仅是一个Oracle的客户和exe
• 各种选项对于建设exe(没有压缩和/或使用拉链文件)

我的测试用例:

testora.py:

import cx_Oracle
import decimal # needed for py2exe to compile this correctly

def testora():
    """testora

    >>> testora.testora()
    <cx_Oracle.Connection to scott@localhost:1521/orcl>
    X
    """
    orcl = cx_Oracle.connect('scott/tiger@localhost:1521/orcl')
    print orcl
    curs = orcl.cursor()
    result = curs.execute('SELECT * FROM DUAL')
    for (dummy,) in result:
        print dummy

if __name__ == '__main__':
    testora()

build_testora.py:

from distutils.core import setup
import py2exe, sys

sys.argv.append('py2exe')

setup(
    options = {'py2exe': {
        'bundle_files': 2,
        'compressed': True
        }},
    console = [{'script': "testora.py"}],
    zipfile = None
    )

结果：

C:\Python26\working>python testora.py
<cx_Oracle.Connection to scott@localhost:1521/orcl>
X

Answer 1

你一定要排除的OCI.dll 当你建立与py2exe?如果版本的错误你的机器是不符合客户的版本，另一台机器上你的测试(我注意到你尝试了一11g客户，但10g你的机器上)，那么这种配置不会的工作(我忘了实际的错误消息，虽然).

Answer 2

订正build_testora.py为未来参考：

from distutils.core import setup
import py2exe, sys

sys.argv.append('py2exe')

setup(
    options = {'py2exe': {
        'bundle_files': 2,
        'compressed': True,
        'dll_excludes': ["oci.dll"]
        }},
    console = [{'script': "testora.py"}],
    zipfile = None
    )
