python - 在 mac OS 上从 python 运行 firefox selenium webdriver 无法启动

Question

当尝试使用下一个简单脚本从 Pycharm IDE 或终端启动 firefox 时:

from selenium import webdriver
a = webdriver.Firefox(firefox_binary='/usr/local/bin/geckodriver')

没有打开浏览器 session ，我遇到了这个问题:

Traceback (most recent call last):
  File "/Users/avihaiezaguy/Desktop/a.py", line 2, in <module>
    a = webdriver.Firefox(firefox_binary='/usr/local/bin/geckodriver')
  File "/Library/Python/2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 150, in __init__
    keep_alive=True)
  File "/Library/Python/2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 92, in __init__
    self.start_session(desired_capabilities, browser_profile)
  File "/Library/Python/2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 179, in start_session
    response = self.execute(Command.NEW_SESSION, capabilities)
  File "/Library/Python/2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 236, in execute
    self.error_handler.check_response(response)
  File "/Library/Python/2.7/site-packages/selenium/webdriver/remote/errorhandler.py", line 104, in check_response
    status = value["status"]
KeyError: 'status'

当 webdriver 在没有二进制文件的情况下从终端调用时，浏览器打开，我得到:

Traceback (most recent call last):
  File "/Users/avihaiezaguy/Desktop/a.py", line 2, in <module>
    a = webdriver.Firefox()
  File "/Library/Python/2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 150, in __init__
    keep_alive=True)
  File "/Library/Python/2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 92, in __init__
    self.start_session(desired_capabilities, browser_profile)
  File "/Library/Python/2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 180, in start_session
    self.session_id = response['sessionId']
KeyError: 'sessionId'

另一方面，Chrome 运行良好。

谁能帮忙解决这个问题？

将 selenium 从 3.0.2 升级到 3.3.1

pip install -U selenium

现在可以了!
