我正在使用Eclipse在Ubuntu上编写Python 2.7.3代码。我是Python和Linux的初学者，同时也在使用模块pythonwifi 0.3.1。该代码将扫描frequency_channel_map中的频率，wifi.scan()应该检索一个包含在for循环中列出的信息的对象。
#!/usr/bin/python2
from pythonwifi.iwlibs import Wireless
frequency_channel_map = {
2412000000: "1",
2417000000: "2",
2422000000: "3",
2427000000: "4",
2432000000: "5",
2437000000: "6",
2442000000: "7",
2447000000: "8",
2452000000: "9",
2457000000: "10",
2462000000: "11",
2467000000: "12",
2472000000: "13",
2484000000: "14",
}
wifi = Wireless("wlan")
for ap in wifi.scan():
print "SSID: " + ap.essid
print "AP: "+ ap.bssid
print "Signal: " + str(ap.quality.getsignallevel())
print "Frequ: "+ str(ap.frequency.getfrequency())
print "Chanel :"+ frequency_channel_map.get(ap.frequency.getfrequency())
print "____"
获取并解决那个问题

IOError: [Errno 1] Operation not permitted
我不知道为什么会发生这种情况。已经搜索了2天的IOError: [Errno 1] Operation not permitted，但没有找到我能理解的东西。
