10.04 – 如何更改我的PYTHONPATH使3,2是我的默认Python而不是2.7.2？

我的python3.2位于/usr/lib/python3.2中.我不确定这是否意味着它已安装,但我认为现在是这样.

关于我的系统的一些事实：

$which python
/usr/local/bin/python

当我在终端输入python时,我得到以下内容

$python
Python 2.7.2 (default, Dec 19 2011, 11:12:13) 
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more @R_193_4045@ion.

然后找到我做的路径

>>> sys.info
>>> sys.path
['', '/usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg', '/usr/local/lib/python2.7/site-packages/pip-1.0.2-py2.7.egg', '/usr/local/lib/python2.7/site-packages/PIL-1.1.7-py2.7-linux-x86_64.egg', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages']

所以知道这一切,如何将我的默认系统python从2.7.2更改为3.2？

解决方法:

更改默认python并不好.许多系统程序依赖于python2而不是python3.如果你想使用python3,你只需输入命令python3.
