如何在 Firefox 中正确使用 selenium？ [复制]

Question

我正在尝试使 selenium 与 Firefox 71.00 x64 en-US 一起工作，我输入的代码是：

from selenium import webdriver
browser = webdriver.Firefox()

但是浏览器没有启动，即使我已经将 geckodriver（最新版本可下载）和 firefox.exe 的目录都添加到系统路径中，我仍然会收到此错误：

  File "C:\Users\Tommaso\AppData\Roaming\Python\Python38\site-packages\selenium\webdriver\common\service.py", line 72, in start
    self.process = subprocess.Popen(cmd, env=self.env,
  File "C:\Users\Tommaso\AppData\Local\Programs\Python\Python38\lib\subprocess.py", line 854, in __init__
    self._execute_child(args, executable, preexec_fn, close_fds,
  File "C:\Users\Tommaso\AppData\Local\Programs\Python\Python38\lib\subprocess.py", line 1307, in _execute_child
    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] Impossibile trovare il file specificato
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

  File "C:\Users\Tommaso\AppData\Roaming\Python\Python38\site-packages\selenium\webdriver\firefox\webdriver.py", line 164, in __init__
    self.service.start()

    raise WebDriverException(
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

通过将geckodriver.exe 添加到与python.exe 相同的目录来修复它。
