proble與soaplib（LXML）用的Apache2 + mod_wsgi的

Question

當我啓動我的應用程序使用的Apache2 + modwsgi 我趕上

 
Exception Type: ImportError 
Exception Value: DLL load failed: The specified module could not be found. 

符合

 
from lxml import etree 

和Django開發服務器一切工作正常 視覺C++ Redistributable 2008安裝

依賴walker告訴msvcrt90.dll錯過了 但是有相同的地方與cx_Oracle相似，但cx_Oracle的dll加載正確

有什麼想法？

的Windows 2003 Server和64位的Windows XP SP3 32位 Python 2.7版32位 cx_Oracle 5.0.4 32位

UPD： 下載libxml2-2.7.7和的libxslt-1.1.26

嘗試建立與setup.py建立--compiler的mingw32

UPD2： 我明白爲什麼導入cx_Oracle工作正常：cx_Oracle.pyd包含「MSVCRT.dll」依賴etree.pyd沒有它

Answer 1

確實是因爲'msvcrt90.dll'。從Python 2.6的微補丁修訂版的某處，他們停止構建擴展模塊的DLL的自動依賴關係，並依賴於Python可執行文件。當嵌入到其他系統中時，您將依賴於鏈接到DLL的可執行文件，而在Apache的情況下則不會。因此，Python的改變已經打破了許多在Windows上嵌入Python的系統，並且唯一的解決方案是每個擴展模塊都有自己的依賴關係，這些DLL依賴於許多不需要的DLL。 psycopg2擴展受到了嚴重的影響，他們已經改變了他們的構建，現在將自己的依賴添加回來。你可能會去尋找psycopg2發生的問題。其中一個解決方案是使用Windows上的MinGW編譯器重新構建擴展。
