我的Python
服务器上安装了两个centOS
版本。
[ethan@demo ~]$ python2.6 --version
Python 2.6.6
[ehtan@demo ~]$ python --version
Python 2.7.3
某些必要的centOS
软件包需要旧版本(2.6),因此我无法将其删除。
当我使用pip
安装软件包时,它们将安装在Python 2.6
中。但我希望将它们安装到Python 2.7
。
如何更改此行为?
例如,以下是我尝试安装Wand
[ethan@demo ~]$ pip install Wand
Requirement already satisfied (use --upgrade to upgrade): Wand in /usr/lib/python2.6/site-packages
Cleaning up...
[ethan@demo ~]$ python2.6
Python 2.6.6 (r266:84292, Jul 10 2013, 22:48:45)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import wand
>>> exit()
[ethan@demo ~]$ python
Python 2.7.3 (default, Oct 11 2013, 15:59:28)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import wand
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named wand
>>> exit()

你需要分别为每个python版本安装pip。
要为Python2.7安装pip,请运行
sudo easy_install-2.7 pip
使用pip-2.7安装Wand
sudo pip-2.7 install Wand
