在我的Mac OS X Lion上，我在terminal中input以下内容：
hobbes3@hobbes3:~$ which python /usr/local/bin/python hobbes3@hobbes3:~$ python Python 2.7.1 (r271:86832, Jun 16 2011, 16:59:05) [GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> ^D hobbes3@hobbes3:~$ /usr/local/bin/python Python 2.7.2 (default, Feb 23 2012, 00:05:44) [GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> 部分/usr/local/bin/如下所示：

为什么我第一次inputpython我得到v2.7.1，但是当我键入完整path/usr/local/bin/python我得到v2.7.2？
我使用自制软件安装了v2.7.2，我想使用该版本，因为我相信我的Django安装在v2.7.2 python下。
因为可怜的bash被混淆了。 清除python的哈希项。
hash -d python
