运行spotify ruby​​脚本时收到encrypted_strings（LoadError）

Question

我正在尝试运行Ruby脚本来设置与spotify的令牌交换。我对Ruby一无所知，所以我不知道如何解决以下错误以响应以下命令：

ruby ./spotify_token_swap.rb
/Users/jeff/.rvm/rubies/ruby-2.1.5-dev/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- encrypted_strings (LoadError)
    from /Users/jeff/.rvm/rubies/ruby-2.1.5-dev/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from ./spotify_token_swap.rb:6:in `<main>'

kernel_require.rb的第54行是：

return gem_original_require(path)

如果有帮助，这是我的RubyGems环境：

gem env

我猜测有一个缺少的宝石，或者我的路径有问题。但我真的不知道。有人可以提供一些关于如何解决这个问题的手段吗？

良好的调试思路，但你有点太深了:)你不需要知道 Kernel.require如何工作，只是那个

  

如果找不到名为的文件，将引发LoadError。

您可能只需要安装encrypted_strings gem。
