Question

我使用的是Ubuntu x64

当我执行以下代码时：

from selenium import webdriver
x = webdriver.Firefox()
x.get('any address')

我得到了一个错误的错误：

 % python seleniumtest.py 
Traceback (most recent call last):
  File "seleniumtest.py", line 2, in <module>
    x = webdriver.Firefox()
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 85, in __init__
    keep_alive=True)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 90, in __init__
    self.start_session(desired_capabilities, browser_profile)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 177, in start_session
    response = self.execute(Command.NEW_SESSION, capabilities)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 234, in execute
    response = self.command_executor.execute(driver_command, params)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/remote_connection.py", line 401, in execute
    return self._request(command_info[0], url, body=data)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/remote_connection.py", line 432, in _request
    resp = self._conn.getresponse()
  File "/usr/lib/python2.7/httplib.py", line 1051, in getresponse
    response.begin()
  File "/usr/lib/python2.7/httplib.py", line 415, in begin
    version, status, reason = self._read_status()
  File "/usr/lib/python2.7/httplib.py", line 371, in _read_status
    line = self.fp.readline(_MAXLINE + 1)
  File "/usr/lib/python2.7/socket.py", line 476, in readline
    data = self._sock.recv(self._rbufsize)
socket.error: [Errno 104] Connection reset by peer

这是什么问题？我该怎么办呢？

我解决了这个问题在终端执行fallowing命令：

终端1：% sudo Xvfb :10 -ac 终端2：$ export DISPLAY=:10

执行以下代码：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()

返回此错误：

 % python seleniumtest.py
Traceback (most recent call last):
  File "seleniumtest.py", line 4, in <module>
    driver = webdriver.Firefox()
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 81, in __init__
    self.binary, timeout)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/extension_connection.py", line 51, in __init__
    self.binary.launch_browser(self.profile, timeout=timeout)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/firefox_binary.py", line 68, in launch_browser
    self._wait_until_connectable(timeout=timeout)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/firefox_binary.py", line 98, in _wait_until_connectable
    raise WebDriverException("The browser appears to have exited "
selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.

我的Firefox和Selenium版本：

% firefox -v
Mozilla Firefox 47.0

 % pip show selenium

Answer 1

尝试使用以下代码：

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

try:
    driver = webdriver.Firefox()
except:
    binary = FirefoxBinary('C:/Program Files (x86)/Mozilla Firefox/firefox.exe')
    driver = webdriver.Firefox(firefox_binary=binary)

也可能是你的Mozilla Firefox版本有问题，当我的Firefox自动更新时，webdriver.Firefox()对我不起作用所以我不得不将Firefox版本降级到36.0

Answer 2

也许你需要Firefoxdriver for selenium。我使用Chrome进行硒，然后下载Chromedriver。您可以从https://sites.google.com/a/chromium.org/chromedriver/downloads下载。你可以参考https://sites.google.com/a/chromium.org/chromedriver/getting-started。

from selenium import webdriver
import time
chrome_driver_path = "/home/shifeng/shifengworld/tool/chrome_driver_downloads/chromedriver"
browser = webdriver.Chrome(executable_path = chromedriver_path)
href = "http://stackoverflow.com"
browser.get(href)
time.sleep(2)

我的需要是可以的。

Selenium Webdrive socket.error
