Question

我是 Ruby 的新手，很少练习。我在编译以下视频中演示的 instabot 时遇到了困难： Build an Instagram autofollow bot

出现的错误是：

C:/Ruby23-x64/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- watir (LoadError)
        from C:/Ruby23-x64/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
        from auto_follow.rb:1:in `<main>'

我的代码是这样的：

require 'watir '
require_relative 'credentials'

username = $username
password = $password

user = 'justinbieber'

#abrir o browser e navegar até a página de login

browser = Watir::Browser.new :chrome
browser.goto = "https://www.instagram.com/accounts/login/"

#navegando para os campos de login e senha e injetando informações
puts "Login in..."
browser.text_field(:name => "username").set "#{username}"
browser.text_field(:name => "password").set "#{password}"


#clicando no botao
browser.button(:class => '_ah57t _84y62 _i46jh _rmr7s').click

sleep(360)

您需要安装 "watir" gem 才能在您的代码中 require 它：

gem install watir

如果你仔细听，around 1:00 youtube 视频会告诉你这一点，但实际上并没有在屏幕上显示出来:)
