Ruby/Heroku Selenium :: WebDriver ::错误:: WebDriver错误:无法连接到chromedriver 127.0.0.1:9516 [英] Ruby / Heroku Selenium::WebDriver::Error::WebDriverError: unable to connect to chromedriver 127.0.0.1:9516

问题描述

我试图用红宝石在Heroku上运行无头铬.我已经安装了构建包 https://github.com/heroku/heroku-buildpack -google-chrome/和 https://github.com/heroku/heroku- buildpack-chromedriver 并已将Selenium driver_path设置到正确的位置(在将其设置为buildpack设置的GOOGLE_CHROME_BIN变量后，我已经像设置Selenium驱动程序路径之前得到了cannot find Chrome binary一样进行了检查.获取unable to connect to chromedriver).

I'm trying to run headless chrome on Heroku with ruby. I've installed the buildpacks https://github.com/heroku/heroku-buildpack-google-chrome/ and https://github.com/heroku/heroku-buildpack-chromedriver and have set the Selenium driver_path to the correct location (I've checked this as before setting the Selenium driver path I get cannot find Chrome binary, after setting it to the GOOGLE_CHROME_BIN variable set by the buildpack I get the unable to connect to chromedriver).

当我尝试使用Watir::Browser.new :chrome或Watir::Browser.new :chrome, headless:true启动Selenium/Watir时，我会得到Selenium::WebDriver::Error::WebDriverError: unable to connect to chromedriver 127.0.0.1:9516

When I try to start Selenium / Watir with Watir::Browser.new :chrome or Watir::Browser.new :chrome, headless:true I get Selenium::WebDriver::Error::WebDriverError: unable to connect to chromedriver 127.0.0.1:9516

任何建议都值得赞赏

推荐答案

由于配置错误以及将正确的选项哈希传递给Watir::Browser.new的组合，我们也遇到了同样的问题.我们正在使用watir (6.10.3)，selenium-webdriver (~> 3.4, >= 3.4.1)和ruby '2.4.0'.

We also had the same problem due to the combination of configuration errors and passing the correct options hash to Watir::Browser.new. We are using watir (6.10.3), selenium-webdriver (~> 3.4, >= 3.4.1) and ruby '2.4.0'.

为了使所有内容都能在Heroku上正常运行，我们添加了以下buildpack:

To get everything working on Heroku we added the following buildpacks:

• https://github.com/heroku/heroku-buildpack-google-chrome
• https://github.com/heroku/heroku-buildpack-chromedriver
• heroku/ruby​​

• https://github.com/heroku/heroku-buildpack-google-chrome
• https://github.com/heroku/heroku-buildpack-chromedriver
• heroku/ruby

要成功初始化浏览器，您需要将路径传递给options哈希内的chromedriver bin. heroku-buildpack-chromedriver为bin搜索路径提供环境变量GOOGLE_CHROME_SHIM.最后，将在本地和Heroku上运行的代码如下所示:

To successfully initialize the browser you need to pass the path to chromedriver bin within the options hash. heroku-buildpack-chromedriver provides an environment variable GOOGLE_CHROME_SHIM for the bin search path. At the end the code which will work locally and on Heroku looks like this:

opts = {
    headless: true
}

if (chrome_bin = ENV.fetch('GOOGLE_CHROME_SHIM', nil))
  opts.merge!( options: {binary: chrome_bin})
end 

browser = Watir::Browser.new :chrome, opts
browser.goto "your url"
