自chrome 85版以来在Heroku上启动无头铬时(ruby)

Question

问题因重复而结束：

1. 这个问题是用红宝石写的，而不是python和

1. 我在那个线程上尝试了解决方案，没有什么改变。编辑我的问题补充一下。

我有一个Heroku应用程序运行构建包：

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

和

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

我的设置与在chrome buidlpack上描述的相同：

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

我在用宝石

gem "selenium-webdriver“

在谷歌Chrome在2020年9月升级到85版之前，这一切都非常顺利。现在它大约成功了5次中的1次，其余4次我得到了这样的错误：

我尝试过向chrome添加额外的参数(即使buildpack自动添加它们)，但没有效果。

我补充了有关这个解决方案的两个论点：

未知错误:会话因页崩溃而被删除，从未知错误:无法确定加载状态从选项卡崩溃与ChromeDriver硒

问题依然存在。

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

但还是没有运气。

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

这让它起作用了。
