selenium.common.exceptions.WebDriverException：消息：“geckodriver”可执行文件需要在 GeckoDriver Selenium Firefox 的 PATH 中

Question

我对 Pycharm 或 Python 的了解不足以解决问题所在。似乎我觉得应该执行这段简单的代码，但我得到一堆乱七八糟的文本，对我没有任何意义。

其他使用 Selenium 的人收到此错误并知道如何修复它？ 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:

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()

Answer 1

对于它可能有什么帮助，回溯的关键部分是

FileNotFoundError: [WinError 2] The system cannot find the file specified

line 3, in <module>
driver = webdriver.Firefox()

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

Firefox 网络驱动程序似乎不在您的主程序看到的已定义搜索路径中。有一个名为 geckodriver 的东西不可用。

检查此软件包的安装和配置。请咨询您的班级导师和同学寻求帮助。我怀疑维修是由您当地的设置引起的，超出了我们这里的知识范围。

Answer 2

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

使用 Selenium v​​3.x 时，您必须从 url 下载最新的 GeckoDriver 并将其存储在您的系统中，并在启动时提及绝对路径webdriver 和 Web Browser 会话如下：

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()
