找不到'rubyzip'（〜> 1.0）

Question

When trying to execute my ruby script I receive the following error message

C:/Ruby24-x64/lib/ruby/2.4.0/rubygems/dependency.rb:308:in `to_specs': Could 
not find 'rubyzip' (~> 1.0) among 14 total gem(s) (Gem::MissingSpecError)
Checked in 'GEM_PATH=C:/Users/me/.gem/ruby/2.4.0;C:/Ruby24-

I run gem env and the following is returned

My script is the sample ruby script on seleniumhq page.

require 'rubygems'
require 'selenium-webdriver'

driver = Selenium::WebDriver.for :IE
driver.get "http://google.com"

element = driver.find_element :name => "q"
element.send_keys "Cheese!"
element.submit

puts "Page title is #{driver.title}"

wait = Selenium::WebDriver::Wait.new(:timeout => 10)
wait.until { driver.title.downcase.start_with? "cheese!" }

 puts "Page title is #{driver.title}"
driver.quit

Thanks, Scott

Answer 1

For some reason I was unable to install rubyzip. I needed to

• download the gem into my system
• navigate to the folder
• execute gem install --force --local *.gem

When I did the above steps the gem was installed.
