python – 从py2exe’d程序连接到Oracle时出错：无法获取Oracle环境句柄

当我使用 Python解释器运行它时,我的python程序(Python 2.6)工作正常,它连接到Oracle数据库(10g XE)而没有错误.但是,当我使用py2exe编译它时,可执行版本在调用cx_Oracle.connect()时失败并显示“无法获取Oracle环境句柄”.

我没有高兴地试过以下事情：

> Oracle即时客户端10g和11g
> Oracle XE客户端
>重新安装cx_Oracle-5.0.2-10g.win32-py2.6.msi
>设置ORACLE_HOME以及PATH
>另一台只有Oracle客户端和exe的计算机
>构建exe的各种选项(无压缩和/或使用zip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:Python26working>python testora.py
<cx_Oracle.Connection to scott@localhost:1521/orcl>
X

C:Python26working>python build_testora.py py2exe
