I have installed python2.7.3 in d:\Python27\python  ,and
mkdir in g:\microblog, downloaded virtualenv.py in g:\microblog,when
cd into g:microblog, i want to install flask in the g:\microblog.

     g:\microblog>d:\Python27\python  virtualenv.py flask
     Overwriting flask\lib\orig-prefix.txt with new content
     New python executable in flask\Scripts\python.exe
     Traceback (most recent call last):
       File "g:\microblog\flask\lib\site.py", line 67, in <module>
         import os
       File "g:\microblog\flask\lib\os.py", line 397
         yield from walk(new_path, topdown, onerror, followlinks)
                  ^
     SyntaxError: invalid syntax
     ERROR: The executable flask\Scripts\python.exe is not functioning
     ERROR: It thinks sys.prefix is u'g:\\microblog' (should be 
u'g:\\microblog\\flas
     k')
     ERROR: virtualenv is not compatible with this system or executable
     Note: some Windows users have reported this error when they 
installed Python for
      "Only this user" or have multiple versions of Python installed. 
Copying the app
     ropriate PythonXX.dll to the virtualenv Scripts/ directory may fix 
this problem.
