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要求pyqt5<；5.13; python_版本>；=“3”，但您有pyqt5 5.15.1。 spyder 4.1.4要求pyqtwebengine<；5.13; python_版本>；=“3”，但您有pyqtwebengine 5.15.1

当我尝试在Pycharm中运行基本程序（如下所示）时，我看到异常：

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")

在处理上述异常期间，发生了另一个异常：

Answer 1

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

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

Answer 2

问题是您向ChromeDriver传递了错误的路径，请尝试将ChromeDriver放在项目目录中。 另外，据我所知，您正在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
