Django 1.5 + TastyPie 0.10 给出“无法导入名称 ModelResource”

Question

更新 Django 和 Tastypie 后，我收到“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 安装更新到 Django 1.5，以及最新版本的 Tastypie。我之前做过两次（一次在我的开发版 MacBook Pro 上，一次在预发布服务器上，与我现在升级的服务器相同）。两次我都记得遇到了麻烦，但两次我都只是让它工作......我不知道怎么做！

它现在已经发生了第三次，我疯狂的“卸载然后重新安装直到它工作”的策略到目前为止已经失败了。我正在运行一个 Apache 服务器，但我的预生产正在运行（我检查了所有 django 和模块版本是否匹配）。

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？

Answer 1

您的 PYTHONPATH 中是否安装了 sweetpie？

---

如果您打开命令提示符（如果您使用它，请确保您在正确的虚拟环境中）并运行：

bash: echo $PYTHONPATH

或者，从在异常点打开的 python 调试器：

>>>import os
>>>os.environ['PYTHONPATH'].split(os.pathsep)

然后确保您安装了tastepie 的目录位于列出的目录之一中。
