Rails: Capyabra / Selenium Chrome-Driver Settings

this worked for me. Since the gem is deprecated, I just uninstalled the gem

 gem uninstall chromedriver-helper

then remove it from your gem file and run:

bundle update

after that, add the webdriver gem in-place, and bundle install

gem 'webdrivers', '~> 4.0'

bundle install

the warnings should be gone

It is not an error,it is a deprecation warning.

The gem chromedriver-helper is deprecated

NOTICE: This gem is out of support as of 2019-03-31 Please use https://github.com/titusfortner/webdrivers instead. See https://github.com/flavorjones/chromedriver-helper/issues/83 for details.

In you gemfile:

group :test do
     gem 'webdrivers', '~> 3.0'
end

group :development, :test do
    gem 'capybara'
end

I'll suggest you to move capybara in the development and test's group, and also update it, if is possible.
