无法在 cloud9 和 aws 中使用 Python 和 selenium 运行 chromedriver

Question

我尝试在 cloud9 和 aws lambda 中使用 python 和 selenium 执行抓取，但是，chromedriver （路径）似乎存在一些问题并且它没有运行。 我的代码是；

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

def lambda_handler(event, context):
    options = Options()
    options.add_argument('--headless')
    path = '/home/ec2-user/environment/testHW/chromedriver.exe'
    url = 'https://www.google.com'
    driver = webdriver.Chrome(executable_path=path, chrome_options=options)
    driver.get(url)
    driver.save_screenshot('screenshot.png')

我已经把chromedriver放在了相应的位置。 但是，我收到如下错误消息；

谁能指出问题出在哪里？

消息：“chromedriver.exe”可执行文件需要在 PATH 中。这个错误意味着它需要一个可执行路径

从您的目录结构看来，您使用的是 linux base os。去这个link 并下载 chromedriver for linux。

打开chromedriver所在的目录，现在打开终端并输入以下命令，允许chromedriver的可执行权限。

sudo chmod +x chromedriver

我希望它会起作用。
