在 Python 中自动下载适合 Selenium 的 chromedriver

Question

不幸的是，Chromedriver 总是特定于您安装的 Chrome 版本。因此，当您通过 PyInstaller 将 python 代码和 chromedriver 打包到 Windows 的可部署 .exe 文件中时，它在大多数情况下都不起作用，因为您将无法在 .exe 文件中拥有所有 chromedriver 版本。

任何人都知道如何从网站自动下载正确的 chromedriver 的方法？

如果没有，我会想出一个代码来下载 zip 文件并将其解压缩到临时文件。

谢谢！

这是另一个解决方案，webdriver_manager不支持。此脚本将下载最新的 chrome 驱动程序版本。import requestsimport wgetimport zipfileimport os# get the latest chrome driver version numberurl = 'https://chromedriver.storage.googleapis.com/LATEST_RELEASE'response = requests.get(url)version_number = response.text# build the donwload urldownload_url = "https://chromedriver.storage.googleapis.com/" + version_number +"/chromedriver_win32.zip"# download the zip file using the url built abovelatest_driver_zip = wget.download(download_url,'chromedriver.zip')# extract the zip filewith zipfile.ZipFile(latest_driver_zip, 'r') as zip_ref:    zip_ref.extractall() # you can specify the destination folder path here# delete the zip file downloaded aboveos.remove(latest_driver_zip)

这是 Python 的另一种方法 -import chromedriver_autoinstallerfrom selenium import webdriveropt = webdriver.ChromeOptions()opt.add_argument("--start-maximized")chromedriver_autoinstaller.install()driver = webdriver.Chrome(options=opt)driver.get('https://stackoverflow.com/')这里有更多信息https://pypi.org/project/chromedriver-autoinstaller/

截至 2021 年 8 月，这是状态：-chromedriver-自动安装程序自动下载并安装支持当前安装的 chrome 版本的 chromedriver。此安装程序支持 Linux、MacOS 和 Windows 操作系统。安装pip install chromedriver-autoinstaller用法Just type import chromedriver_autoinstaller in the module you want to use chromedriver.例子from selenium import webdriverimport chromedriver_autoinstallerchromedriver_autoinstaller.install()  # Check if the current version of chromedriver exists                                      # and if it doesn't exist, download it automatically,                                      # then add chromedriver to pathdriver = webdriver.Chrome()driver.get("http://www.python.org")assert "Python" in driver.title
