我有一个简单的脚本blah.py(使用Python 2):

import sys
print sys.argv[1]

如果我执行我的脚本:

python c:/..../blah.py argument

它打印参数,但如果我执行脚本:

blah.py argument

发生错误:

IndexError ...

所以参数不会传递给脚本.

PATH中的python.exe.blah.py的文件夹也在PATH中.
python.exe是执行*.py文件的默认程序.

问题是什么？

当我开始金字塔pserve时,我得到了这个堆栈跟踪:

% python $(which pserve) ../etc/development.ini
Traceback (most recent call last):
  File "/home/hughdbrown/.local/bin/pserve", line 9, in <module>
    load_entry_point('pyramid==1.5', 'console_scripts', 'pserve')()

    return command.run()

我需要为.py文件设置关联以使用特定的python版本执行.但我需要仅为单个cmd.exe会话建立此关联(并行会话不应受影响).Windows是否允许这样做？

我怀疑答案是否定的,但是我希望看到一些证据,然后再将这个功能转化为virtualenv.
