更新Django& Tastypie我收到一个“无法导入名称ModelResource”。我该如何解决这个问题?
我目前正在尝试将Django安装更新为Django 1.5,以及最新版本的Tastypie。我之前已经完成了两次(一次在我的开发MacBook Pro上,再次在预发布服务器上,与我现在正在升级的服务器相同)。两次我都记得有麻烦,但两次我都让它工作......我不知道怎么做!
现在已经发生了第三次,我的疯狂“卸载然后重新安装直到它工作”策略到目前为止失败了。我正在运行Apache服务器,但我的预生产工作正常(我已经检查过所有django和模块版本都匹配)。
有没有人遇到过这个问题并且没有解决这个问题的神奇序列?

你的PYTHONPATH安装了tastypie吗?
如果你打开一个命令提示符(如果你使用它,请确保你在正确的虚拟环境中)并运行:
bash: echo $PYTHONPATH
或者,从异常点打开的python调试器:
>>>import os
>>>os.environ['PYTHONPATH'].split(os.pathsep)
然后确保您安装tastypie的目录位于列出的目录之一。
