selenium.common.exceptions.WebDriverException：消息：“ geckodriver”可执行文件必须与GeckoDriver Selenium Firefox一起放入PATH

Question

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，但我却看到一堆乱七八糟的文字，对我什么也没说。

使用Selenium的其他人会收到此错误，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"
Traceback (most recent call last):

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

During handling of the above exception, another exception occurred:

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

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()

Answer 2

对于可能没有多大帮助，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.

似乎Firefox Webdriver不在您的主程序看到的已定义搜索路径中。 有一个叫geckodriver的东西不可用。

检查此软件包的安装和配置。 向您的班主任和同学咨询以寻求帮助。 我怀疑维修是您本地设置的事情，这超出了我们的了解。
