我安装了这个
我想在所有这些python安装上测试代码。
（关于缺少对Python 2.4./2.5的支持的相关问题： How do I setup virtualenv environments for Python 2.4 and 2.5 versions on Windows?）
这是我到目前为止所尝试的：
直接尝试virtualenv：
Python 2.6按预期工作：
C:\Users\martin\.virtualenvs>virtualenv -p c:\apps\Python26\python.exe env26
Running virtualenv with interpreter c:\apps\Python26\python.exe
New python executable in env26\Scripts\python.exe
Installing Setuptools..............done.
Installing Pip.............done.
C:\Users\martin\.virtualenvs>env26\Scripts\activate
(env26) C:\Users\martin\.virtualenvs>python
Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
Python 2.7和3.3也可以按预期工作。
尝试使用virtualenvwrapper：
Python 2.6,2.7和3.3按预期工作：
C:\Users\martin\.virtualenvs>mkvirtualenv -p c:\apps\Python26\python.exe env26_w
Running virtualenv with interpreter c:\apps\Python26\python.exe
New python executable in env26_w\Scripts\python.exe
Installing Setuptools.........done.
Installing Pip................done.
(env26_w) C:\Users\martin\.virtualenvs>python
Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
在Powershell上尝试virtualenvwrapper：
创建和激活Python 2.6不会出错，但会启动Python27 激活时：
PS C:\Users\martin> mkvirtualenv -p C:\apps\Python26\python.exe env_26_ps
New python executable in env_26_ps\Scripts\python.exe
Installing Setuptools........done.
Installing Pip.......................done.
Added activation script por Powershell to C:\Users\martin\.virtualenvs/env_26_ps\Scripts.
(env_26_ps)PS C:\Users\martin> python
Python 2.7.6 (default, Nov 10 2013, 19:24:18) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
env_26_ps\Scripts文件夹包含pip-2.7.exe和python.exe（2.7）等文件。
Python 3.3的类似行为
