unittest導入錯誤與virtualenv +谷歌應用程序引擎Django

Question

我正在與谷歌應用程序引擎Django +壓縮django。只要運行「python manage.py test」就可以成功，而且不會出錯。

但與virtualenv，測試失敗，導入unittest錯誤。與Django 1.1相同的錯誤。

- 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 

錯誤消息：

我也試圖與控制檯的進口，但它是好的。

> which python

這裏是我的環境：

$ mkvirtualenv --no-site-packages no-django 
$ mkvirtualenv --no-site-packages django-1.1 
$ mkvirtualenv --no-site-packages django-1.1.1 
(django-1.1)$ easy_install Django-1.1.tar 
(django-1.1.1)$ easy_install Django-1.1.1.tar 
$ mkdir google-app-engine-django-svn 
$ cp -r google-app-engine-django-svn google-app-engine-django-svn-django-1.1 
// copy appropriate django.zip 
$ cp -r google-app-engine-django-svn google-app-engine-django-svn-django-1.1.1 
// copy appropriate django.zip 

Answer 1

這是相當複雜的實現。我研究瞭如何創建一個 的virtualenv - GAE - 現在Django的組合，我會回來 與後來的更多信息，但是這是我現在所擁有的：

這裏的一個區別是，我使用Django-nonrel，但我也嘗試過 google-app-engine-django，並且在virtualenv方面，他們似乎 的工作原理是一樣的。

的virtualenv'd Python解釋器將無法直接啓動manage.py ：Django的manage.py和dev_appserver.py要廣泛 控制sys.path，明顯的方式，使共存 用的virtualenv可能。

然而，共存一定程度似乎是可能的：

我創建這樣的目錄結構：

./src < - Django的nonrel來源和我的消息來源 djangoappengine/< - 從wkornewald的到位桶來源 的Django/< - 也wkornewald的到位桶.. /< - 我們的應用程序

./www < - 我的Django根 manage.py，app.yaml中，settings.py，模板/等。 共應用/ < - Django的nonrel這裏要包 .google_appengine < - 鏈接到我的安裝GAE

我使用'python2.5 manage.py runserver'在 上面的'www /'目錄啓動開發服務器。

（基本處於 http://rh0dium.blogspot.com/2010/02/development-strategy-for-google-app.html 由rh0dium建議的目錄結構）

創建我在上面的頂層目錄的virtualenv：

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

然後，我把兩個文件中的lib/python2。5 /站點包：

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 

（這些文件可能/（應該）被分開了，但我把它簡單的 現在。

這樣做與正確設置setup.py結合創建 開發蛋至少le我有一個交互式提示，可以導入Django設置可以導入的所有東西，用於播放和 測試。
