unittest导入错误与virtualenv +谷歌应用程序引擎Django

Question

我正在与谷歌应用程序引擎Django +压缩django。只要运行“python manage.py test”就可以成功，而且不会出错。

但与virtualenv，测试失败，导入unittest错误。与Django 1.1相同的错误。

- OSX 10.5.6 
- google-app-engine-django (r101 via svn) : r100 was failed with launcher 1.3.0 
- GoogleAppLauncher 1.3.0 
- Django 1.1 & 1.1.1 (zipped) : both failed 
- virtualenv 1.4.5 
- virtualenvwrapper 1.24 

错误消息：

Answer 1

这是相当复杂的实现。我研究了如何创建一个 的virtualenv - GAE - 现在Django的组合，我会回来 与后来的更多信息，但是这是我现在所拥有的：

这里的一个区别是，我使用Django-nonrel，但我也尝试过 google-app-engine-django，并且在virtualenv方面，他们似乎 的工作原理是一样的。

的virtualenv'd Python解释器将无法直接启动manage.py ：Django的manage.py和dev_appserver.py要广泛 控制sys.path，明显的方式，使共存 用的virtualenv可能。

然而，共存一定程度似乎是可能的：

我创建这样的目录结构：

./src < - Django的nonrel来源和我的消息来源 djangoappengine/< - 从wkornewald的到位桶来源 的Django/< - 也wkornewald的到位桶.. /< - 我们的应用程序

./www < - 我的Django根 manage.py，app.yaml中，settings.py，模板/等。 共应用/ < - Django的nonrel这里要包 .google_appengine < - 链接到我的安装GAE

我使用'python2.5 manage.py runserver'在 上面的'www /'目录启动开发服务器。

（基本处于 http://rh0dium.blogspot.com/2010/02/development-strategy-for-google-app.html 由rh0dium建议的目录结构）

创建我在上面的顶层目录的virtualenv：

$ virtualenv --python=python2.5 --no-site-packages --distribute . 

然后，我把两个文件中的lib/python2。5 /站点包：

gae.pth，

<full path to GAE> 
<full path to GAE>/lib/antlr3 
<full path to GAE>/lib/webob 
<full path to GAE>/lib/yaml/lib 

和django-nonrel.pth：

<project path>/src/django-nonrel 
<project path>/src 

（这些文件可能/（应该）被分开了，但我把它简单的 现在。

这样做与正确设置setup.py结合创建 开发蛋至少le我有一个交互式提示，可以导入Django设置可以导入的所有东西，用于播放和 测试。
