ruby - 协议(protocol).rb :153:in `read_nonblock' : end of file reached (EOFError)

Question

我的 ruby​​ selenium-driver 脚本出现问题，该脚本直到最近一直运行良好。我想不出我对我的环境所做的任何更改可能会阻止它工作。

代码如下:

#!/usr/bin/env ruby

require 'capybara'
require 'selenium-webdriver'
require 'pry'
require 'capybara/dsl'

Capybara.register_driver :chromedriver do |app|
  Capybara::Selenium::Driver.new(app, :browser => :chrome)
end

Capybara.current_driver = :chromedriver

class BulkDoAction
  include Capybara::DSL

  def initialize(file)
    @value_ids = File.readlines file
  end

  def delete(value_id)

    puts "#{Time.now} -> saving value=#{value_id}"
    visit "https://www.url.com/#{value_id}/confirmSave"

    click_button "Save"
    sleep 5.0
  end

  def run
    visit 'https://www.url.com/login'

    fill_in 'Email or Username', with: 'XXX'
    fill_in 'password', with: 'XXX'
    click_button "Login"
    sleep 5.0

    @value_ids.each_with_index do |val_id, idx|
      puts "Doing #{idx + 1} out of #{@value_ids.size}"
      delete val_id.to_i
      sleep 3.0
    end
  end
end

BulkDoAction.new('test.txt').run

我更改了一些值，因为其中包含敏感信息。

但是，每当我将其运行为:

./bulk.rb

我得到以下异常:

    from ./bulk.rb:63:in `<main>'

当我同时运行 brew 安装的 ruby​​ 并强制运行 2.0.0 系统 ruby​​ 时，我得到了这个。

我觉得我的 gem 和正在阅读的剧本有问题，但我无法弄清楚。

这是我的 gem 列表:

addressable (2.4.0)
archive-zip (0.7.0)
bigdecimal (1.2.6)
capybara (2.10.1)
childprocess (0.5.9)
chromedriver-helper (1.0.0)
coderay (1.1.1)
ffi (1.9.14)
io-console (0.4.3)
io-like (0.3.0)
json (1.8.1)
method_source (0.8.2)
mime-types (3.1)
mime-types-data (3.2016.0521)
mini_portile2 (2.1.0)
minitest (5.4.3)
multi_json (1.12.1)
nokogiri (1.6.8.1)
power_assert (0.2.2)
pry (0.10.4)
psych (2.0.8)
rack (2.0.1)
rack-test (0.6.3)
rake (10.4.2)
rdoc (4.2.0)
rubyzip (1.2.0)
selenium-webdriver (3.0.0)
slop (3.6.0)
test-unit (3.0.8)
webdriver-firefox (0.0.15)
websocket (1.2.3)
xpath (2.0.0)

所以澄清一下，当 chrome 打开时，我什至没有访问 URL，它停留在“数据；”然后在终端抛出异常。

脚本没有任何变化，所以我认为这与我的环境有关。

如果有人有任何想法，我将不胜感激，同时我会继续努力弄清楚!

我发现了同样的错误，我已经将 chromedriver 升级到版本 2.25 (chromedriver_mac64.zip 2016-10-22 06:23:51 4.35MB)。

现在，它运行得非常好。
