无法运行webdriver.selenium webdriver的Firefox

Question

I am having trouble using Selenium

I am using Python 3.6, on a Windows 7 machine at my workplace. Firefox is 61.0.1 (64-bit) Python is loaded in C:\\Program Files (x86)\\Python36-32

My work is in H:\\PythonPrograms

I have successfully installed selenium: C:\\Windows\\System32> pip install selenium Requirement already satisfied: selenium in c:\\program files (x86)\\python36-32\\lib\\site-packages (3.13.0)

Per other advice found here, I downloaded geckodriver.exe and placed it both into C:\\Program Files (x86)\\Python36-32 and H:\\PythonPrograms .

My path includes: C:\\Program Files (x86)\\Python36-32\\Scripts\\;C:\\Program Files (x86)\\Python36-32\\;H:\\PythonPrograms

I am following the steps on "Automate the Boring Stuff with Python" (Al Sweigart) p. 257

>>> from selenium import webdriver
>>> browser = webdriver.Firefox()
Traceback (most recent call last):
  File "<pyshell#4>", line 1, in <module>
    browser = webdriver.Firefox()
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 159, in __init__
    log_path=log_path)
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\selenium\webdriver\firefox\service.py", line 44, in __init__
    log_file = open(log_path, "a+") if log_path is not None and log_path != "" else None
PermissionError: [Errno 13] Permission denied: 'geckodriver.log'


>>> browser = webdriver.Firefox(executable_path=r'H:\PythonPrograms')
Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    browser = webdriver.Firefox(executable_path=r'H:\PythonPrograms')
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 159, in __init__

PermissionError: [Errno 13] Permission denied: 'geckodriver.log'

(IT's not the permissaion on geckodriver.log. This even happens when I delete that file and try again. Also I checked permissions: )

When I run Python as administrator from a new Python session:

>>> from selenium import webdriver
>>> browser = webdriver.Firefox(executable_path=r'H:\PythonPrograms')
Traceback (most recent call last):
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\selenium\webdriver\common\service.py", line 76, in start
    stdin=PIPE)
  File "C:\Program Files (x86)\Python36-32\lib\subprocess.py", line 709, in __init__
    restore_signals, start_new_session)
  File "C:\Program Files (x86)\Python36-32\lib\subprocess.py", line 997, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    browser = webdriver.Firefox(executable_path=r'H:\PythonPrograms')
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 160, in __init__
    self.service.start()
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\selenium\webdriver\common\service.py", line 83, in start
    os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'PythonPrograms' executable needs to be in PATH.

I don't understand what is happening between me running Python normally vs running as administrator. Whichever, neither way gives me expected output.

added new run example by changing the executable_path to include the program name and remove the "r" qualifier. Here are the new results:

>>> from selenium import webdriver
>>> browser = webdriver.Firefox(executable_path='H:\PythonPrograms\geckodriver.exe')
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    browser = webdriver.Firefox(executable_path='H:\PythonPrograms\geckodriver.exe')
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 170, in __init__
    keep_alive=True)
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 156, in __init__
    self.start_session(capabilities, browser_profile)
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 251, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 320, in execute
    self.error_handler.check_response(response)
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.SessionNotCreatedException: Message: Unable to find a matching set of capabilities

而不是使用正则表达式，请尝试使用exe文件名提供确切的路径

browser = webdriver.Firefox(executable_path='H:\PythonPrograms\yourexenamehere.exe')
