Django（mod_wsgi）处理WSGI脚本时发生异常

Yao Hong Kok 发表于 Dev

姚洪角

我是Apache和mod_wsgi的初学者。我了解Apache服务器的基本思想。我需要救生员，因为我几乎没有人可以寻求帮助。

我的问题如下：

  1. 我可以运行，python manage.py runserver 0.0.0.0:8000并且我的应用程序可以在服务器上正常运行
  2. 但是，当我使用Apache服务器为我的网站提供服务时。事情进展不顺利。

返回的两个主要错误是：

 ImproperlyConfigured: Error loading psycopg2 module: /opt/payupjack/payupjack-env/lib/python2.7/site-packages/psycopg2/_psycopg.so: wrong ELF class: ELFCLASS32

和

  ImproperlyConfigured: Error importing middleware django_openid.consumer: "cannot import name utils"

资料夹结构

payupjack
  |-payupjack-env (virtualenv for payupjack)
      |- (virtualenv stuffs...)
      |- PayupJack (My application)
           |- All the code required by this application

我尝试过的

  1. 将virtualenv的site-package文件夹中的django_openid文件夹的用户所有权更改为“ www-data”

  2. 将“ www-data”用户添加到“ ubuntu”组（以便“ www-data”与“ ubuntu”享有相同的特权）

  3. 单独运行“ wsgi.py”，可以正常运行。

  4. 运行python manage.py runserver也很好

  5. 试图注释掉导入utils模块consumer.py（在django_openid模块中）的行，但是我仍然遇到相同的错误。这真的很奇怪，我不知道如何理解。

  6. 遵循了许多关于此问题的不同变体的Stackoverflow建议。到目前为止，一切都没有。

额外的信息

完整的Apache错误日志返回以下内容。

我还对整个硬盘进行了快速查找，只找到了一个与上述内容相匹配的python库，该库位于：

/usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0
姚洪角

该问题是由于路径问题引起的（感谢Graham指出了如何检查的位和位置psycopg2.so）。我的应用程序使用VirtualEnv。由于某些原因，我第一次没有正确设置VirtualEnv。因此，所有通过安装的软件包都pip保留在操作系统的python路径中，而不是VirtualEnv。

解决方案是删除操作系统的Python路径上安装的所有软件包。然后，重新创建一个新的VirtualEnv并执行典型的操作pip install。确保所有软件包都安装在VirtualEnv路径中。一旦这样做，一切都会变得很漂亮。
