Django haystack 语法错误

Question

我正在尝试运行一个在我同事的机器上运行良好的 Django 项目，但是当我尝试运行server.

时我从 haystack 收到一个错误

我在你安装的应用程序中包含 haystack。

Linux ubuntu 3.5.0-44-generic #67-Ubuntu SMP 11 月 12 日星期二 19:36:14 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Python 3.2.3

pip 6.0.8 来自 /usr/local/lib/python3.2/dist-packages (python 3.2)

Name: django-haystack
Version: 2.3.1
Location: /usr/local/lib/python3.2/dist-packages
Requires: Django

欢迎提出任何想法

谢谢

这似乎是 Python 版本问题。 Python 3.2 没有字符串的 u 前缀，因为字符串在 Python 3 中默认是 unicode。前缀在 Python 3.3 中重新引入，以便与 2.7 兼容更容易.见 3.3 release notes.

请注意 PyPI page for Haystack 2.3.1 提到 3.3+ 作为要求。

您应该将 Python 版本升级到 3.3。
