Question

我正在运行Selenium和PhantomJS将搜索词输入网站并检索每个搜索词的点击次数。我必须这样做130,000次以上，所以代码运行良好一天，直到程序突然出现以下错误：

Traceback (most recent call last):
  File "CBBPlyNwsScrape.py", line 82, in <module>
     browser = webdriver.PhantomJS()
  File "/Library/Python/2.7/site-packages/selenium/webdriver/phantomjs/webdriver.py", line 50, in __init__
     self.service.start()
  File "/Library/Python/2.7/site-packages/selenium/webdriver/phantomjs/service.py", line 69, in start
     raise WebDriverException("Can not connect to GhostDriver")
selenium.common.exceptions.WebDriverException: Message: 'Can not connect to GhostDriver'

我在Mac OSX和Python 2.7.3上运行它。我安装了Selenium和PhantomJS的最新版本。任何人都可以告诉我发生了什么以及为什么GhostDriver长时间正常工作并突然停止了吗？

在ghostdriver.log文件中，这是它包含的全部内容：

PhantomJS is launching GhostDriver...
[ERROR - 2013-12-01T05:14:34.491Z] GhostDriver - Main - Could not start Ghost Driver => {

     {
        "sourceURL": ":/ghostdriver/main.js",
        "line": 82
     }
  ]
}

安装最新的幻像js修复了这个错误，这是在默认的ubuntu 12.04 phantomjs destro中发生的

Answer 2

我遇到了同样的问题。我不知道为什么程序在调用phantomJS webdriver时遇到问题，但答案是编写一个简单的异常WebDriverException。以下代码为我做了诀窍

from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException, WebDriverException
import unittest, time, re, urllib2

f = open("mother.txt","r") #opens file with name of "test.txt"
l = "1"
m = "2"
n = "3"
aTuple = ( l, m, n ) # create tuple
e = int(0)


for line in f:          
    e += 1
    try:
        h = str(e)
        j = line
        g = open("yes4/" + h + ".txt","w") #opens file with name of "test.txt"
        for item in aTuple:
            driver = webdriver.PhantomJS('phantomjs')
            base_url = j + item
            verificationErrors = []
            accept_next_alert = True
            driver.get(base_url)
            elem=driver.find_element_by_id("yelp_main_body")
            source_code=elem.get_attribute("outerHTML").encode('utf-8').strip()
            g.write(source_code)
            driver.quit()
    except WebDriverException:
        print "e"       
        h = str(e)
        j = line
        g = open("yes4/" + h + ".txt","w") #opens file with name of "test.txt"
        for item in aTuple:
            driver = webdriver.PhantomJS('phantomjs')
            base_url = j + item
            verificationErrors = []
            accept_next_alert = True
            driver.get(base_url)
            elem=driver.find_element_by_id("yelp_main_body")
            source_code=elem.get_attribute("outerHTML").encode('utf-8').strip()
            g.write(source_code)
            driver.quit()
    else:
        print h
