它在django 1.4.2+上运行良好，我使用的是 django1.4 然后升级它

pip install django==1.4.5 --upgrade

Django 1.3有问题smart_bytes，从您的回溯中它显示相同的错误，它已在Django 1.4中解决，尝试将Django升级到最新版本1.5。

见https://github.com/django/django/blob/master/django/utils/encoding.py#L149

此外，在升级 Django 之前，请务必查看发行说明。

更新：

很抱歉，哇，真是个脑残；）。

我不知道该函数的完整历史，但查看 Github 上的 django.utils.encoding .. 标记为 1.3.7；此文件不包含 Tastypie 尝试导入的函数。https://github.com/django/django/blob/1.3.7/django/utils/encoding.py

如果你无法升级 Django，你需要修补你的 Tastypie.utils.dict 文件以使用你所拥有的。
