我正在完成 TestFirst Teaching 中的 Pig Latin 练习，但在制作 Ruby 文件并尝试运行 rake 后，出现以下错误：

我认为这可能与我正在运行的版本有关，但我完全不确定。

Mac OSX 10.8.2
Ruby 1.8.7 Rspec
2.13.1
Rake 10.0.4

笔记！当我在之前的练习（0-3）上运行 rake 时，它​​们工作得很好，但之后就没有任何效果了......

编辑：我更新了我的 rake 版本，现在当我尝试运行 rake 时，我仍然收到“rspec_config failed”错误，但我也得到了这个。帮助！！！

编辑#2：这是我的 Pig Latin 练习的源代码，因为它说这是一个语法问题。

def isvowel?(letter)
  vowels = ["a", "e", "i", "o", "u"]
  vowels.include?(letter)
end

def translate(word)
  i = 0
  cons = []

  while !isvowel?(word[i])
    cons << word[i]
    i+=1
  end

  word[i..-1] + cons.join()[0…i] + "ay"
end

def translates(string)
  if !string.include?(" ")
    translate(string)
  else
    new = string.split(" ").collect { |word| translate(word) }
  end

  new.join(" ")
end

它在 cons.join()[0…i] + "ay" 上窒息 - 我注意到你看起来很奇怪......这不是标准......

您是否复制并粘贴了这部分代码？... （一个奇怪且不需要的字符）和 ... （正确的 ruby​​ 运算符）之间的区别是破坏它的原因。只需删除另一个字符并手写点。
