我从下面的代码部分收到上述错误。是什么原因？

 1  require 'spec_helper'
 2
 3  before(:all) do
 4    puts "ServerSpec tests on #{ENV['TARGET_HOST']}"
 5  end

完全错误：

【解决方案1】：

before应该在describe内实现：

require 'spec_helper'

describe "My Tests" do
  before(:all) do
    puts "ServerSpec tests on #{ENV['TARGET_HOST']}"
  end
end

祝你好运！

您似乎错过了描述您的班级。如果没有describe，对象将成为接收者，而您将拥有NoMethodError。轻松修复：

describe MyClass do
  before(:all) do
    #
  end
end
