Python apache2+；mod_wsgi

当我使用apache2+modwsgi启动应用程序时 我抓住

异常类型：ImportError 异常值：DLL加载失败：找不到指定的模块。 一致

from lxml import etree 从lxml导入etree 使用Django开发服务器，一切正常 Visual C++可重新分配2008安装< /P> Dependency walker告诉我们缺少msvcrt90.dll 但cx_Oracle也有同样的情况，但cx_Oracle的dll加载正确

有什么想法吗

windows 2003服务器64位和windows XP sp3 32位 python 2.7 32位 cx_Oracle 5.0.4 32位

UPD： 下载libxml2-2.7.7和libxslt-1.1.26

尝试使用setup.py build--编译器mingw32生成

我理解为什么导入cx_Oracle工作正常：cx_Oracle.pyd包含“MSVCRT.dll”依赖项，而etree.pyd没有它

这确实是因为“msvcrt90.dll”。在Python2.6的微补丁修订版中，他们停止为扩展模块自动构建DLL依赖项，而是依赖Python可执行文件来完成。但是，当嵌入到其他系统中时，您依赖于链接到DLL的可执行文件，而Apache则不依赖。因此，Python的变化打破了许多在Windows上嵌入Python的系统，唯一的解决方案是每个扩展模块都对所需的DLL有自己的依赖关系，而许多扩展模块都没有。psycopg2扩展受到了严重的影响，他们现在已经更改了构建，将依赖项添加回自己的内部。您可以在psycopg2出现问题时搜索该问题。解决方案之一是在Windows上使用MinGW编译器重建扩展
