Ubuntu下Django环境搭建

参考：http://docs.djangoproject.com/en/dev/topics/install/#installing-development-version
 
以下内容根据上面的文档和网上资料整理一个完整步骤，方便参考
 
1. 获取最新Django,放到~/python路径下
 
svn co http://code.djangoproject.com/svn/django/trunk/ ~/python/django-trunk
 
  2. 创建软连接
 
首先查看SITE-PACKAGES-DIR： python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"

$ python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"
/usr/lib/python2.5/site-packages
$ export SITE-PACKAGES-DIR=/usr/lib/python2.5/site-packages
$ ln -s ~/python/django-trunk/django-trunk/django $SITE-PACKAGES-DIR/django
$ ln -s ~/python/django-trunk/django/bin/django-admin.py /usr/local/bin
 
现在我们就可以在任意目录执行django-admin.py startproject xx了
 
3 创建工程
 
$ pwd
~/share
$ django-admin.py startproject test
 
4 现在来试试看
$ python
Python 2.5.2 (r252:60911, Oct  5 2008, 19:24:49)

>>> from django.template import Template, Context
>>> t=Template('Simple Test')

根据报告的错误到网上找到了一篇文章：http://blog.csdn.net/mooninday/archive/2008/10/17/3092023.aspx

现在按这篇文章的方法来做
方法一：
>>> from django.template import Template, Context
>>> from django.conf import settings
>>> settings.configure()
>>> t = Template('My name is {{ my_name }}.')
>>> c = Context({'my_name': 'Daryl Spitzer'})
>>> t.render(c)

ok通过
 
方法二：
先确定python的路径
$ which python2.5
/usr/bin/python2.5
$ export PYTHONPATH=/usr/bin/python2.5:~/share
$ export DJANGO_SETTINGS_MODULE=test.settings
 
其中:~/share是django工程test所在的路径
测试一下
>>> from django.template import Template, Context
>>> from django.conf import settings
>>> t = Template('My name is {{ my_name }}.')
>>> c = Context({'my_name': 'Daryl Spitzer'})
>>> t.render(c)
 
ok通过

在Ubuntu中将
export PYTHONPATH=/usr/bin/python2.5:~/share
export DJANGO_SETTINGS_MODULE=test.settings
加到~/.profile文件中，每次登录就自动设置了
