我在运行命令包时遇到问题exec guard init rspec

Question

我正在阅读railstutorial.org的书。

我收到此错误：

$ bundle exec guard init rspec c:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/guard-2.0.3/lib/guard/interactor.rb:1:in require': cannot load such file -- pry (LoadError) from c:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/guard-2.0.3/lib/guard/inter actor.rb:1:in ' from c:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/guard-2.0.3/lib/guard/dsl.r b:2:in require' from c:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/guard-2.0.3/lib/guard/dsl.r b:2:in ' from c:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/guard-2.0.3/lib/guard.rb:6: in require' from c:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/guard-2.0.3/lib/guard.rb:6: in ' from c:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/guard-2.0.3/bin/guard:3:in require' from c:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/guard-2.0.3/bin/guard:3:in ' from c:/Ruby200-x64/bin/guard:23:in load' from c:/Ruby200-x64/bin/guard:23:in '

我的宝石文件为：1。 源 'https://rubygems.org' 红宝石 '2.0.0'

我缺少的东西？谢谢你的帮助！

明确添加pry或类似于您Gemfile。我使用pry-nav，当bundle install运行时，它会自动捆绑pry。

# Gemfile 
gem 'pry-nav', group: [:development, :test]

看起来像守卫需要pry被安装。

gem install pry
