ruby - 自 Chrome 版本 85 起在 Heroku 上启动无头 chrome 时出现 Selenium webdriver 错误（ruby）

Question

问题因重复而被关闭：

1. 这个问题是在 ruby​​ 中，而不是 python 和

2. 我在那个线程上尝试了解决方案，没有任何改变。编辑我的问题添加。

我有一个运行 buildpacks 的 Heroku 应用程序：

https://github.com/heroku/heroku-buildpack-google-chrome/

和

https://github.com/heroku/heroku-buildpack-chromedriver

我的设置与 chrome buidlpack 上描述的设置相同：

chrome_bin = ENV.fetch('GOOGLE_CHROME_SHIM', nil)

chrome_opts = chrome_bin ? { "chromeOptions" => { "binary" => chrome_bin } } : {}

Capybara.register_driver :chrome do |app|
  Capybara::Selenium::Driver.new(
    app,
    browser: :chrome,
    desired_capabilities: Selenium::WebDriver::Remote::Capabilities.chrome(chrome_opts)
  )
end

Capybara.javascript_driver = :chrome
session = Capybara::Session.new(:chrome)
session

在 2020 年 9 月将 Google Chrome 更新到版本 85 之前，这一直运行良好。现在它大约有五分之一的成功，另外四次我收到此错误：

我尝试向 chrome 添加其他参数（即使 buildpack 自动添加它们）无济于事。

我在这个解决方案中添加了两个论点：

未知错误：由于未知错误导致页面崩溃，会话被删除：无法从 ChromeDriver Selenium 崩溃的选项卡中确定加载状态

问题仍然存在。

chrome_opts = { "chromeOptions" => { "binary" => chrome_bin#,
                                          args: %w[headless disable-gpu no-sandbox disable-dev-shm-usage]
                                          } }

但仍然没有运气。

所以我的问题是：

How do I tell the buildpack to stick to chrome version 84? or

How do I avoid the error from happening on version 85 and above?

谢谢

Answer 1

Capybara.register_driver :chrome do |app|
  Capybara::Selenium::Driver.new app, browser: :chrome,
    options: Selenium::WebDriver::Chrome::Options.new(args: %w[headless disable-gpu disable-dev-shm-usage])
end

Capybara.javascript_driver = :chrome

这使它工作。
