Gem :: Specification.reset期间未解决的规格：
启动Guard时，我得到以下输出： $ guard WARN: Unresolved specs during Gem::Specification.reset: lumberjack (>= 1.0.2) ffi (>= 0.5.0) WARN: Clearing out unresolved specs. Please report a bug if this causes problems. 这是什么意思，我该如何解决？ Guardfile的内容： guard 'livereload' do watch(%r{.+\.(css|js|html)$}) end guard 'sass', :input => 'css', :style => :compressed, :extension => '.min.css'
