※ 引述《smile2359630 (。。。)》之銘言： : 小弟剛步入linux系統沒多久而已,目前遇到一個問題 : 我想在macbook上使用speedometer這個網路監測軟體,想說都是以unix下去發展出來的OS, : 執行上照理說可行的，但目前遇到下面問題 : speedometer -rx eth0 時顯示以下 : Traceback (most recent call last): : File "/usr/local/bin/speedometer", line 1093, in <module> : console() : File "/usr/local/bin/speedometer", line 797, in console : wait_all(cols) : File "/usr/local/bin/speedometer", line 1088, in wait_all : tap.wait_creation() : File "/usr/local/bin/speedometer", line 856, in wait_creation : if self.feed() is None: : File "/usr/local/bin/speedometer", line 610, in networkfn : f = open('/proc/net/dev') : IOError: [Errno 2] No such file or directory: '/proc/net/dev' 這個程式寫法是抓 linux 特有的 /proc/net/dev 分析內容，所以 linux 適合使用， mac 沒該檔案所以運作失敗。要改寫支援 mac 也很簡單，剛看一下大約這樣子 /usr/local/bin/speedometer.py 檔案打開，幾個地方要改： 1. 找一下一開始 import 部分語法 #!/usr/local/opt/python@2/bin/python2.7 # speedometer.py # Copyright (C) 2001-2011 Ian Ward # # This module is free software; you can redistribute it and/or # modify it under the terms of the GNU Lesser General Public # License as published by the Free Software Foundation; either # version 2.1 of the License, or (at your option) any later version. # # This module is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU # Lesser General Public License for more details. __version__ = "2.8" import time import sys import os import string import math import re 在 import re 之後，多加一行: import psutil 2. 下面這段要改: def network_feed(device,rxtx): """network_feed(device,rxtx) -> function that returns given device stream speed rxtx is "RX" or "TX" """ assert rxtx in ["RX","TX"] r = re.compile(r"^\s*" + re.escape(device) + r":(.*)$", re.MULTILINE) def networkfn(devre=r,rxtx=rxtx): f = open('/proc/net/dev') dev_lines = f.read() f.close() match = devre.search(dev_lines) if not match: return None parts = match.group(1).split() if rxtx == 'RX': return long(parts[0]) else: return long(parts[8]) return networkfn 改成： def network_feed(device,rxtx): """network_feed(device,rxtx) -> function that returns given device stream speed rxtx is "RX" or "TX" """ assert rxtx in ["RX","TX"] r = re.compile(r"^\s*" + re.escape(device) + r":(.*)$", re.MULTILINE) def networkfn(devre=r,rxtx=rxtx): if rxtx == 'RX': return psutil.net_io_counters(pernic=True)[device].bytes_recv else: return psutil.net_io_counters(pernic=True)[device].bytes_sent return networkfn 主要是 networkfn() 裡面改改就好。最後系統用 pip install psutil 安裝上該 python module，剛剛跑一下可以運作。 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 122.117.155.17 ※ 文章網址: https://www.ptt.cc/bbs/Linux/M.1523509703.A.842.html
