Question

我好多年没有编程了。我正在尝试学习自动化工作任务。在遇到一些问题后，我能够成功为 Python 安装 selenium。

这是我试图测试以确保安装成功的简单程序。

注意 - 我在安装 selenium 时遇到问题，所以我必须设置路径和其他一些东西。所以我认为其中一些变化可能影响了这个 Python 程序的运行。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()

当我在命令提示符下运行程序时，这就是我得到的。

>py main.py
Traceback (most recent call last):
  File "C:\Users\jonab\AppData\Local\Programs\Python\Python39\lib\site-packages\selenium\webdriver\common\service.py", line 72, in start
    self.process = subprocess.Popen(cmd, env=self.env,

    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

    driver = webdriver.Firefox()

    raise WebDriverException(

我确实参考了这篇文章并运行了他们的代码，但遇到了不同的错误。 Python Selenium Traceback (most recent call last):
