Serverspec错误：“不知道如何构建任务”

Serverspec出现问题。我试图从一个CloudBees jenkins构建服务器使用ansible来测试部署在云VM上的基础架构。我使用Serverspec为每个角色创建了一个测试。现在我只是想检查我是否可以正确运行测试，并连接到我的虚拟机。Serverspec错误：“不知道如何构建任务”

事情是，一旦我运行“rake spec”，我会得到一个“不知道如何构建任务”规范：84'“错误，这不在我的代码中。

整个日志是在这里：

这里是我的Rakefile：

1 require 'rake' 
    2 require 'rspec/core/rake_task' 
    3 
    4 hosts = %w(
    5 84.39.33.93 
    6) 
    7 
    8 task :spec => 'spec:all' 
    9 
10 namespace :spec do 
11 task :all => hosts.map {|h| 'spec:' + h.split('.')[0] } 
12 hosts.each do |host| 
13  short_name = "sca-vm" 
14  role  = "common" 
15 
16  desc "Run serverspec to #{host}" 
17  RSpec::Core::RakeTask.new(short_name) do |t| 
18  ENV['TARGET_HOST'] = host 
19  t.pattern = "spec/base,#{role}/*_spec.rb" 
20  end 
21 end 
22 end                   
~

spec_helper.rb：

require 'serverspec' 
require 'net/ssh' 

set :backend, :ssh 

if ENV['ASK_SUDO_PASSWORD'] 
    begin 
    require 'highline/import' 
    rescue LoadError 
    fail "highline is not available. Try installing it." 
    end 
    set :sudo_password, ask("Enter sudo password: ") { |q| q.echo = false } 
else 
    set :sudo_password, ENV['SUDO_PASSWORD'] 
end 

host = ENV['TARGET_HOST'] 

options = Net::SSH::Config.for(host) 

options[:user] ||= Etc.getlogin 

set :host,  options[:host_name] || host 
set :ssh_options, options 

# Disable sudo 
# set :disable_sudo, true 


# Set environment variables 
# set :env, :LANG => 'C', :LC_MESSAGES => 'C' 

# Set PATH 
# set :path, '/sbin:/usr/local/sbin:$PATH'

最后，这里是我使用的test_spec它只是验证一个名为now.txt的plaint文本文件的存在：

require 'spec_helper' 

describe file('~/now.txt') do 
    it { should be_file } 
end

我现在很困惑。你们能帮我理解发生了什么吗？

代码段

hosts.map {|h| 'spec:' + h.split('.')[0] }

单独收率：[ “规格：84”]。现在，任务规范：全部取决于该任务。在循环开始

hosts.each do |host|

有只定义了一个任务，它被称为“SCM-VA”：

RSpec::Core::RakeTask.new(short_name) do |t| 
    # ... 
end

另外请注意，这个任务是为主机的每一个元素定义（在你的例如，这只是一个，但你假设hosts是一个数组，因为我认为）。

在命令行上尝试rake -T -A以列出所有任务，即使是没有说明的任务，也可以查看Rake实际已知的任务。

换句话说：代码示例声明spec：所有依赖于未定义的任务（或任务）。

如果更改行

RSpec::Core::RakeTask.new('spec:' + host.split('.')[0]) do |t|

代码不会引发异常，但我不知道能解决你的问题。也许重要的是'scm-vm'实际上是任务名称的一部分。

但是，如果这就是你想要的，你应该将host.split('.')[0]重构为它自己的方法。
