如何在Repl.it上使用硒？

Question

我正在尝试在Repl中使用Selenium，但是由于某些原因，它似乎不起作用，有什么方法可以修复这个问题吗？

chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')

driver = webdriver.Chrome(options=chrome_options)

driver.get("https://www.youtube.com/watch?v=dQw4w9WgXcQ")

views = driver.find_element_by_class("view-count style-scope ytd-video-view-count-renderer")
print(views)

这是我似乎要犯的两个错误。

Answer 1

您需要转到replit.nix，单击隐藏的文件，然后您将看到它，您需要将pkgs.chromium和pkgs.chromedriver导入到dep中。

{ pkgs }: {
deps = [
    pkgs.python38Full
    pkgs.chromium
    pkgs.chromedriver
];
