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”。
我尝试了下面的事情并不高兴：
ORACLE_HOME以及PATH 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

cx_Oracle.InterfaceError: Unable to acquire Oracle environment handle
答案 0 :(得分：8)
在使用py2exe构建时，您确定要排除OCI.dll吗？如果您机器上的DLL版本与另一台机器上的客户端版本不兼容，那么您测试它（我注意到您在机器上尝试了11g客户端但是10g），那么此配置将无法工作（我忘记了实际的错误消息）虽然）。
答案 1 :(得分：2)
修改build_testora.py，以备将来参考：
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
)
