selenium.common.exceptions.WebDriverException：消息：“ geckodriver”可执行文件必须在GeckoDriver Selenium Firefox的PATH中

问题内容：

我不了解Pycharm-或Python足够好以解决问题所在。在我看来，似乎应该执行这些简单的代码，但我却收到一堆乱七八糟的文字，对我什么也没说。

其他使用Selenium的人都会收到此错误，知道如何解决吗？物理代码-

"C:\Users\Noah Linton\PycharmProjects\EdgenuityBot\venv\Scripts\python.exe" 
"C:/Users/Noah Linton/PycharmProjects/EdgenuityBot/Edgenuity Bot"

During handling of the above exception, another exception occurred:

os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' 
executable needs to be in PATH.


Process finished with exit code 1

执行代码

 from selenium import webdriver

driver = webdriver.Firefox()
driver.get("https://auth.edgenuity.com/Login/Login/Student")
button = driver.find_element_by_id('LoginSubmit')
button.click()

问题答案：

错误说明了一切：

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

这意味着 GeckoDriver 二进制文件不在 Classpath中

使用 Selenium v​​3.x时， 您必须从该
URL
 下载最新的 GeckoDriver
并将其存储在系统中，并在启动 Webdriver 和 Web Browser 会话时提及绝对路径，如下所示：
__
 

from selenium import webdriver

driver = webdriver.Firefox(executable_path="C:\\path\\to\\geckodriver.exe")
driver.get("https://auth.edgenuity.com/Login/Login/Student")
button = driver.find_element_by_id('LoginSubmit')
button.click()
