Question

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')

没有打开浏览器会话，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'

当从终端调用没有二进制文件的webdriver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工作正常。

任何人都可以帮忙解决这个问题吗？
