我正在编写一个程序,它将在网站上搜索文章中的特定条目,我正在使用selenium webdriver for Python.

在尝试连接到网站时,我遇到了以下异常:

Traceback (most 
recent call last):
  File "search.py", line 26, in <module>
    test.search_for_keywords()
  File "search.py", line 13, in search_for_keywords
    browser = webdriver.Firefox()
  File "C:\Python27\lib\site-packages\selenium-3.0.0b2-py2.7.egg\selenium\webdriver\firefox\webdriver.py", line 65, in __init__
    self.service.start()
  File "C:\Python27\lib\site-packages\selenium-3.0.0b2-py2.7.egg\selenium\webdriver\common\service.py", line 86, in start
    self.assert_process_still_running()
  File "C:\Python27\lib\site-packages\selenium-3.0.0b2-py2.7.egg\selenium\webdriver\common\service.py", line 99, in assert_process_still_running
    % (self.path, return_code)
selenium.common.exceptions.WebDriverException: Message: Service geckodriver unexpectedly exited. Status code was: 2

它说网络驱动程序意外退出.我该如何解决这个问题？我正在尝试使用python版本2.7.12与firefox版本48.0连接

我有一个程序可以为我创建工作笔记,它有效,但是有一个我想摆脱的尾随破折号:

def prompt(input)
  print "[#{Time.now.strftime('%T')}] #{input}: "
  STDIN.gets.chomp
end

def work_performed
  count = 0
  notes = ''
  while true
    input = prompt("Enter work notes[#{count += 1}]")
    notes << "\n" + "#{input}\n"
    if input.empty?
      return notes
    else
      while input.empty? != true
        input = prompt('Enter work notes[*]')
        notes << "  - #{input}\n"
      end
    end
  end
end

运行时:

test
  - tset  
  -
test  
  - tset  
  - 
tset  
  - tset  
  - 

我怎样才能重构这个以消除关卡末端的尾随破折号？
