系统，PIP和Virtualenv上的Python 2.7仍使用2.6-如何将它们切换为使用2.7 [英] Python 2.7 on System, PIP and Virtualenv still using 2.6 - How do I switch them to use 2.7

问题描述

我在MacOSx 10.6.8上，并且安装了python 2.7

I am on MacOSx 10.6.8 and I have python 2.7 installed

python -v产生:

python -v produces:

Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
dlopen("/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/readline.so", 2);
import readline # dynamically loaded from /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/readline.so

我跑了:

$ virtualenv venv

然后

$ . venv/bin/activate

然后执行python -v

and do a python -v

我得到:

Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49) 
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
dlopen("/Users/nkhdev/venv/lib/python2.6/lib-dynload/readline.so", 2);
import readline # dynamically loaded from /Users/nkhdev/venv/lib/python2.6/lib-dynload/readline.so

有人可以告诉我在我的系统中使用virtualenv创建和使用python 2.7的步骤吗?或拥有virtualenv，请使用python 2.7期间.我不在乎该版本是否是我的系统版本.

Can someone tell me the steps to use have virtualenv create and use python 2.7 from my system? Or have virtualenv, use python 2.7 period. I don't care if the version is my system version.

推荐答案

您可能使用了Apple提供的现有easy_install版本来安装pip等.默认情况下，easy_install与Python的特定实例相关联，在这种情况下，此实例为Apple提供的系统Python 2.6.通常，当您安装新版本的Python时，还需要为其安装新的easy_install.按照此处的说明中的说明，提供提供easy_install的Distribute软件包，然后使用它来安装pip并使用该pip安装virtualenv.

You probably used an existing, Apple-supplied version of easy_install to install pip et al. By default, easy_install is associated with a particular instance of Python, in this case, the Apple-supplied system Python 2.6. In general, when you install a new version of Python, you need to also install a new easy_install for it. Follow the instructions here for the Distribute package which provides easy_install, then use it to install pip and use that pip to install virtualenv.
