一個pymssql 的程序在解釋器上運行正常，但是用py2exe打包后，提示
ImportError: No module named _mssql
百度了半天無果，然后bing,結果bing還是比百度靠譜，某神網的這段話，讓我有了靈感，英語真心不怎么好滴說：
FYI there is a separate newsgroup for py2exe at gmane.comp.python.py2exe. You may want to post there also. Just as a suggestion, put an import decimal at the top of your program. It looks like _mssql might be doing dynamic imports in __load method which will "confuse" py2exe because it can't know about dynamic imports which happen at runtime. -Larry Bates Chris wrote: I've just completed a project using the following (Windows XP, python 2.4.1, wxpython 2.6, and pymssql 0.7.3). The program runs great, but after I convert it to an exe (required for this project), it gives me the following error when I try to run it. Traceback (most recent call last): File "EstUpdate.py", line 6, in ? File "frmSplash.pyc", line 9, in ? File "pymssql.pyc", line 23, in ? File "_mssql.pyc", line 9, in ? File "_mssql.pyc", line 7, in __load ImportError: No module named decimal However, when I look in c:\python24\lib on the machine which ran py2exe, I see decimal.py and decimal.pyc. Can someone please help with this? I'm supposed to start testing the program today and I can't seem to move past this first step. Thanks!! Chris
解決辦法就是這句話：
Just as a suggestion, put an import decimal at
the top of your program. It looks like _mssql
might be doing dynamic imports in __load method
which will "confuse" py2exe because it can't
know about dynamic imports which happen at
runtime.
運行exe的時候提示缺什么模塊就import什么模塊，並在代碼里面顯示的調用一次，我在程序里是調用了__version__,如下代碼：
1 # -*- coding:gbk -*- 2 import pymssql 3 import _mssql 4 import uuid 5 import decimal 6 7 decimal.__version__ 8 uuid.ctypes.__version__ 9 _mssql.__version__
調用之后，打包完直接就可以運行了。
