Selenium Webdriver管道损坏，命令之间有间隔时出错？

Question

Ubuntu 18.x + selenium webdriver(Firefox)

面对一个怪异的问题，如果我run全部一起使用，以下代码块将起作用

from selenium import webdriver

url = 'https://indiamart.com'

driver = webdriver.Firefox()

driver.get(url)

driver.find_element_by_xpath(xpath).click()

url我尝试过的每件事都在发生这种情况。

但是，如果我一次执行一行，它会给出

Traceback (most recent call last):

  File "<input>", line 1, in <module>

  File "/media/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 326, in get

    self.execute(Command.GET, {'url': url})

  File "/media/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 312, in execute

    response = self.command_executor.execute(driver_command, params)

  File "/media/lib/python3.6/site-packages/selenium/webdriver/remote/remote_connection.py", line 472, in execute

    return self._request(command_info[0], url, body=data)

  File "/media/lib/python3.6/site-packages/selenium/webdriver/remote/remote_connection.py", line 495, in _request

    self._conn.request(method, parsed_url.path, body, headers)

  File "/usr/lib/python3.6/http/client.py", line 1239, in request

    self._send_request(method, url, body, headers, encode_chunked)

  File "/usr/lib/python3.6/http/client.py", line 1285, in _send_request

    self.endheaders(body, encode_chunked=encode_chunked)

  File "/usr/lib/python3.6/http/client.py", line 1234, in endheaders

    self._send_output(message_body, encode_chunked=encode_chunked)

  File "/usr/lib/python3.6/http/client.py", line 1065, in _send_output

    self.send(chunk)

  File "/usr/lib/python3.6/http/client.py", line 986, in send

    self.sock.sendall(data)

BrokenPipeError: [Errno 32] Broken pipe

这是error在code

driver.get(url)

但是，如果我在执行之后再次执行同一行，Broken Pipe error则会得到url。

我非常非常困惑。有人可以帮我吗。

Answer 1

这是最新版本的geckodriver v0.21.0与最新版本的硒v3.11相匹配的已知错误。要变通解决此错误，请执行以下操作：a）将geckodriver降级到v0.20.1或更早的版本b）等待在即将发布的selenium和/或geckodriver版本中推出该错误修正/缓解措施此错误源于Keep-Alive功能v 0.21中新增的支持。但是，来自geckodriver的默认超时为0.21设置为5s，这特别短。
