Question

运行时，我收到此脚本的错误另外我应该提一下我刚开始学习Python

import requests
import subprocess
import json
import sys
import threading
import time
from Queue import Queue

numberOfViewers = int(sys.argv[1])
builderThreads = int(sys.argv[2])
startTime = time.time()
numberOfSockets = 0
concurrent = 25
urls = []
urlsUsed = []

def getURL(): # Get tokens
    output = subprocess.Popen(["livestreamer", "twitch.tv/ispazzcraft", "-j"], stdout=subprocess.PIPE).communicate()[0]
    return json.loads(output)['streams']['worst']['url'] # Parse json and return the URL parameter

def build(): # Builds a set of tokens, aka viewers
    global numberOfSockets
    global numberOfViewers
    while True:
        if numberOfSockets < numberOfViewers:
            numberOfSockets += 1
            print "Building viewers " + str(numberOfSockets) + "/" + str(numberOfViewers)
            urls.append(getURL())

def view(): # Opens connections to send views
    global numberOfSockets
    while True:
        url=q.get()
        requests.head(url)
        if (url in urlsUsed):
            urls.remove(url)
            urlsUsed.remove(url)
            numberOfSockets -= 1
        else:
            urlsUsed.append(url)
        q.task_done()

if __name__ == '__main__':
    for i in range(0, builderThreads):
        threading.Thread(target = build).start()

    while True:
        while (numberOfViewers != numberOfSockets): # Wait until sockets are built
            time.sleep(1)

        q=Queue(concurrent*2)
        for i in range(concurrent):
            try:
                t=threading.Thread(target=view)
                t.daemon=True
                t.start()
            except:
                print 'thread error'
        try:
            for url in urls:
                print url
                q.put(url.strip())
                q.join()
        except KeyboardInterrupt:
            sys.exit(1)

这是错误

Traceback (most recent call last):
  File "C:\Python27\Scripts\test.py", line 9, in <module>
    numberOfViewers = int(sys.argv[1])
IndexError: list index out of range

其他人说他们通过安装请求包修复了它，我做了但我仍然收到此错误我也看了，我确实有最新版本的请求包

您应该提供2个命令行参数（数字）来使用此脚本：

numberOfViewers = int(sys.argv[1])
builderThreads = int(sys.argv[2])

例如，如果脚本的名称是test.py：

test.py 1 2

Python请求包脚本错误
