Question

我已经使用无堆栈Python设置了Apache2 mod_python环境，它正在运行。当我使用sys.version测试Python环境时，它会显示

2.5.2 Stackless 3.1b3 060516 (python-2.52:76701, Dec  8 2009, 02:13:34) 
[GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu4)]

在浏览器中。

但当我import stackless显示时：

MOD_PYTHON ERROR

此外，我无法加载MySQLdb，nltk等。所有这些模块都可以在命令行中加载。所以我的猜测是某种程度上mod_python引用旧的Python安装。

可能是什么问题？

我已经针对无堆栈安装了所有内容。如您所见，我对sys.version的回复是

2.5.2 Stackless 3.1b3 060516 (python-2.52:76701, Dec 8 2009, 02:13:34) [GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu4)]

这是代码的回复：

import sys
def index(req):
  return sys.version

但是，如果我在下面添加import stackless，则会抛出上述错误：

import sys
import stackless
def index(req):
  return sys.version

我有什么遗失的东西吗？

mod_python是针对特定版本的Python编译的，只会调用该版本。你可能需要针对Stackless重新编译它，假设这是可能的。

mod_python没有加载无堆栈的Python
