selenium + firefox + webdriver 遇到的坑

lunix中启动webdriver时报错一：

测试代码为：

#!/usr/bin/python
# -*- coding: utf-8 -*-


from selenium import webdriver

driver = webdriver.Firefox()
driver.get("https://www.baidu.com")

运行报错信息如下：

Traceback (most recent call last):
  File "maimai_web.py", line 14, in <module>
    driver = webdriver.Firefox()
  File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/firefox/webdriver.py", line 152, in __init__
    keep_alive=True)
  File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 98, in __init__
    self.start_session(desired_capabilities, browser_profile)
  File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 188, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 256, in execute
    self.error_handler.check_response(response)
  File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py", line 194, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status 1

处理方法：

#!/usr/bin/python
# -*- coding: utf-8 -*-


from pyvirtualdisplay import Display
from selenium import webdriver


display = Display(visible=0, size=(1920, 1080))
display.start()
driver = webdriver.Firefox()
driver.get("https://www.baidu.com")

结果：

运行ok，搞定！

坑二、webdriver实例化报错

采用多线程调用webdriver时候，偶尔会出现这样的错：selenium.common.exceptions.WebDriverException: Message: connection refused

Exception in thread Thread-2:
Traceback (most recent call last):
  File "/usr/local/python3.6/lib/python3.6/threading.py", line 916, in _bootstrap_inner

    response = self.execute(Command.NEW_SESSION, parameters)
  File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 256, in execute
