從py2exe'd程序連接到Oracle時出錯：無法獲取Oracle環境句柄

Question

當我使用Python解釋器運行python程序（Python 2.6）時，它正常工作，它連接到Oracle數據庫（10g XE）而沒有錯誤。但是，當我使用py2exe進行編譯時，可執行版本在調用cx_Oracle.connect（）時出現「Unable to acquire Oracle environment handle」失敗。

我已經試過沒有快樂如下：

• Oracle即時客戶端10g和11g
• 的Oracle XE客戶端
• 重新安裝cx_Oracle-5.0.2-10g.win32-py2.6。微星
• 設置ORACLE_HOME以及PATH
• 另一臺計算機上只是一個Oracle客戶端和EXE
• 爲buildi各種選項納克的exe（無壓縮和/或使用的壓縮文件）

我的測試用例：

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 
    ) 

結果：

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

Answer 1

當您使用py2exe構建時，您是否確保排除OCI.dll？如果你的機器上的DLL版本與你測試的其他機器上的客戶機版本不兼容（我注意到你嘗試了11g客戶機，但是在你的機器上嘗試了10g），那麼這個配置將不起作用（我忘記了實際的錯誤信息雖然）。

Answer 2

修訂build_testora.py，以供將來參考：

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 
    )
