Django-ImportError:无法导入名称

我有一个错误，我在Django 1.6.2和Django 1.5.5上安装了所有应用程序，并且有相同的问题

我的设置是：

Django 1.5.5

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # Uncomment the next line to enable the admin:
    'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    # 'django.contrib.admindocs',
    'polib',
    'easymode',
    'localeurl',
    'rosetta',
    'efc',
)

Django 1.6.2

INSTALLED_APPS += (
    "polib",
    "easymode",
    "localeurl",
    "rosetta",
    "efc",
)

下面是错误：

我都安装了。仍然有错误

你能帮忙吗

谢谢更新：

Rentgeen发现，问题出在django rosetta 0.7.4版本上。见下面他的评论

---

看起来你没有安装django rosetta。跑

pip install django-rosetta

从控制台。这将安装django rosetta及其相关设备（六个、请求和polib）

如果您安装了django rosetta，但没有安装polib，请运行

pip install polib

---

作为旁注，如果您计划在您的帐户上安装几个python项目，您可能需要查看virtualenv教程（针对Web派系或其他：），我强烈建议。

如果您在控制台中执行命令

import rosetta

或

import polib

，您会得到什么？您好，感谢您的回复，它们已经安装在sys路径和httpd.conf:，仍然不知道为什么仍然有错误。问题是django rosetta 0.7.4，我安装了0.7.0，现在可以工作：）奇怪的错误。我将要安装0.7.3，如果它有一个错误或什么。。。

pip install polib
