File "C:UsersAdministratorAppDataLocalProgramsPythonPython36-32libsite-packageswifiscan.py", line 39, in all

stderr=subprocess.STDOUT)

我们打开C:UsersAdministratorAppDataLocalProgramsPythonPython36-32libsite-packageswifiscan.py

找到`    def all(cls, interface):
    """
    Returns a list of all cells extracted from the output of iwlist.
    """
    try:
        iwlist_scan = subprocess.check_output(['/sbin/iwlist', interface, 'scan'],
                                              stderr=subprocess.STDOUT)
    except subprocess.CalledProcessError as e:
        raise InterfaceError(e.output.strip())
    else:
        iwlist_scan = iwlist_scan.decode('utf-8')
    cells = map(Cell.from_string, cells_re.split(iwlist_scan)[1:])

    return cells`
    
    其中这句我们发现 哦 这TMD写死了  
     iwlist_scan = subprocess.check_output(['/sbin/iwlist', interface, 'scan'],
                                              stderr=subprocess.STDOUT)
         所以你的windows完全不支持 /sbin/iwlist wlan0 scan 这条命令啊 这是在linux下运行的。。。
