py2exeのプログラムからOracleに接続する際のエラー：Oracle環境ハンドルを取得できません

Question

Pythonインタプリタを使用してPythonプログラムを実行すると、pythonプログラム（Python 2.6）が正常に動作し、エラーなしでOracleデータベース（10g XE） 。ただし、py2exeを使用してコンパイルすると、cx_Oracle.connect（）の呼び出し時に実行可能なバージョンが「Oracle環境ハンドルを取得できません」というエラーが発生します。

ノー喜びで、次の試してみた：

• のOracleインスタントクライアント10gおよび11g
• のOracle XE Clientの
• をcx_Oracle-5.0.2-10g.win32-py2.6を再インストールします。 ORACLE_HOMEだけでなく、PATH
• ちょうどOracleクライアントを持つ別のコンピュータやexeファイルbuildiため
• さまざまなオプションを設定するMSI
• exeファイル（圧縮なしおよび/または使用したzipファイルを）ngの

私のテストケース：

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：

Answer 1

py2exeでビルドしたときにOCI.dllを除外していることを確認しましたか？マシン上のDLLのバージョンが、別のマシンのクライアントバージョンと互換性がない場合（私は11gのクライアントを試してみたが、マシン上で10gを試してみた）、この設定は機能しませんしかし）。今後の参考のため

Answer 2

改訂build_testora.py、：

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 
    )
