Selenium WebDriver - 无法连接到 Mozilla geckodriver

Question

自从我上次设置 Centos 7 服务器后，我无法再运行自动化案例了你能帮忙吗？

我的宝石文件如下：

source 'https://rubygems.org' git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.5.3'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' gem 'rails', '~> 5.2.2'
# Use sqlite3 as the database for Active Record gem 'sqlite3', '~> 1.3.6'
# Use Puma as the app server gem 'puma', '~> 3.11'
# Use SCSS for stylesheets gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets gem 'uglifier', '>= 1.3.0'
# See https://github.com/rails/execjs#readme for more supported runtimes
# gem 'mini_racer', platforms: :ruby

# Use CoffeeScript for .coffee assets and views gem 'coffee-rails', '~> 4.2'
# Turbolinks makes navigating your web application faster. Read more: https://github.com/turbolinks/turbolinks gem 'turbolinks', '~> 5'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder gem 'jbuilder', '~> 2.5'

# Reduces boot times through caching; required in config/boot.rb gem 'bootsnap', '>= 1.1.0', require: false

group :development, :test do   # Call 'byebug' anywhere in the code to stop execution and get a debugger console   gem 'byebug', platforms: [:mri, :mingw, :x64_mingw] end

group :development do   # Access an interactive console on exception pages or by calling 'console' anywhere in the code.   gem 'web-console', '>= 3.3.0'   gem 'listen', '>= 3.0.5', '< 3.2'   # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring   gem 'spring'   gem 'spring-watcher-listen', '~> 2.0.0' end

gem 'rspec'

group :test do   
# Adds support for Capybara system testing and selenium driver
gem 'capybara', '>= 2.15'
gem 'selenium-webdriver'
# Easy installation and use of chromedriver to run system tests with Chrome 
gem 'chromedriver-helper'
gem 'geckodriver-helper'
gem 'cucumber-rails', :require => false
gem 'database_cleaner'
gem 'rspec-retry'
gem 'rubyXL' 
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data 
gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

我已经从 [change log][1] 尝试了 3.12.0 之前的所有版本，但每次仍然得到相同的错误，如下所示：

  unable to connect to Mozilla geckodriver 127.0.0.1:4444 (Selenium::WebDriver::Error::WebDriverError)

已经半天多了，还没找到合适的解决方案。

谢谢！

可能有用，2 周后我得到了解决方案，当时捆绑更新更新了一些 gem，然后 Chrome 和 Frirefox 浏览器成功启动。
