python - 安装和运行 Selenium、Pycharm 时出错

问题描述

我刚刚安装了 selenium，当我进行 pip 检查 selenium 时，我看到以下内容：qdarkstyle 2.8.1 需要 helpdev，但未安装。spyder 4.1.4 有要求 pyqt5<5.13; python_version >= "3"，但是你有 pyqt5 5.15.1。spyder 4.1.4 要求 pyqtwebengine<5.13; python_version >= "3"，但是你有 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")

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: '../Drivers/chromedriver.exe'

在处理上述异常的过程中，又出现了一个异常：

Traceback (most recent call last):

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

解决方案

您的错误可能与您的 Chrome 驱动程序有关。您可以webdriver-manager 用于安装此模块使用pip install webdriver-manager并将此行粘贴到您的脚本中

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