Question

當我試圖對任何給定的Ruby文件運行spec測試時，我在Emacs中發現了這個錯誤。我的寶石是以標準方式設置的，模塊和課程在lib/，規格測試在spec/。我的.emacs文件包含以下條目：

;;紅寶石東西

(add-to-list 'load-path "~/.emacs.d/plugins/rvm.el") 
(require 'rvm) 
(autoload 'ruby-mode "ruby-mode" 
    "Mode for editing ruby files" t) 
(setq interpreter-mode-alist 
     (append '(("ruby" . ruby-mode)) 
      interpreter-mode-alist)) 
(autoload 'run-ruby "inf-ruby" 
    "Run an inferior Ruby process (irb)" t) 
(autoload 'inf-ruby-keys "inf-ruby" 
    "Set local key bindings for inf-ruby in ruby-mode") 
(add-to-list 'auto-mode-alist '("\\.rake$" . ruby-mode)) 
(add-to-list 'auto-mode-alist '("\\.gemspec$" . ruby-mode)) 
(add-to-list 'auto-mode-alist '("\\.rake$" . ruby-mode)) 
(add-to-list 'auto-mode-alist '("/[Rr]akefile$" . ruby-mode))

rspec的模式uses compilation--ensure-parse on line 435，在rspec-compilation-mode-font-lock-keywords變量。功能compilation--ensure-parse是在Emacs 24.1中引入的，所以推測rspec模式不能保證在早期的Emacs版本上工作。
