安装和运行Selenium、Pycharm时出错

Question

我刚刚安装了selenium，当我对selenium进行pip检查时，我看到了以下内容：qdarkstyle 2.8.1需要未安装的helpdev。spyder 4.1.4具有要求pyqt5<5.13；python_version>="3〃；，但你有第5.15.1节。spyder 4.1.4具有pyqtwebengine<5.13；python_version>="3〃；，但是您有pyqtwebengine 5.15.1。

当我尝试在Pycharm中运行一个基本程序(如下所示(时，我看到了异常：

import time
from selenium import webdriver
driver = webdriver.Chrome("../Drivers/chromedriver.exe")
driver.set_page_load_timeout(10)
driver.get("http://google.com")
driver.find_element_by_name("q").send_keys("Automation step by step")
driver.find_element_by_name("btnK").click()
time.sleep(2)
driver.close()
driver.quit()

print("Test")

在处理上述异常的过程中，发生了另一个异常：

driver = webdriver.Chrome("../Drivers/chromedriver.exe")

问题是，您将错误的路径传递到ChromeDriver，请尝试将ChromeDrive放在Project目录中。此外，据我所知，您在Windows操作系统上运行，您需要将ChromeDriver添加为sys PATH变量上的exe文件。

您的错误可能与Chrome驱动程序有关。可以使用webdriver-manager要安装此模块，请使用pip install webdriver-manager并将此行粘贴到您的脚本

from webdriver_manager.chrome import ChromeDriverManager driver = webdriver.Chrome(ChromeDriverManager().install())
