def _is_dev_mode():
    # quick hack to check if the program is running in dev mode.
    # if 'has_key' in os.environ  
    if os.environ.has_key('SERVER_SOFTWARE') \
        or os.environ.has_key('PHP_FCGI_CHILDREN') \
        or 'fcgi' in sys.argv or 'fastcgi' in sys.argv \
        or 'mod_wsgi' in sys.argv:
           return False
    return True

在上面的代码中显示以下错误

if os.environ.has_key('SERVER_SOFTWARE') \
AttributeError: '_Environ' object has no attribute 'has_key'
