"Autoloading未能定义函数Haskell -交互式-带来“在Emacs上运行Haskell的问题

Question

在haskell repl in emacs之后，我可以安装软件包。我使用MELPA稳定存储库('("melpa-stable" . "http://stable.melpa.org/packages/") t))

• ghc
• 哈斯克尔模式
• 飞检
• 飞检-haskell

我还用cabal安装了二进制文件。

• 阴谋集团安装ghc-mod (5.3.0.0)
• 阴谋集团安装快乐(1.19.5)

MacOSX10.10.4上的阴谋版本1.22.6.0，GNU Emacs版本24.5.1。

问题是，当我尝试用C-‘运行ghci时，我收到了错误消息。

command-execute: Autoloading failed to define function haskell-interactive-bring

对于C-c C-l，我有一条错误消息。

command-execute: Autoloading failed to define function haskell-process-load-or-reload

可能出什么事了？

这是init.el中与Haskell相关的代码。

;; Haskell

; http://www.mew.org/~kazu/proj/ghc-mod/en/preparation.html
(autoload 'ghc-init "ghc" nil t)
(autoload 'ghc-debug "ghc" nil t)
(add-hook 'haskell-mode-hook (lambda () (ghc-init)))
;;(add-hook 'haskell-mode-hook 'turn-on-haskell-indentation).

  (setenv "PATH" (concat my-cabal-path ":" (getenv "PATH")))
  (add-to-list 'exec-path my-cabal-path))
(custom-set-variables '(haskell-tags-on-save t))

(add-hook 'haskell-mode-hook 'turn-on-haskell-indentation)

(eval-after-load 'haskell-mode '(progn

  (define-key haskell-mode-map (kbd "C-c C-n C-c") 'haskell-process-cabal-build)
  (define-key haskell-mode-map (kbd "C-c C-n c") 'haskell-process-cabal)))
(eval-after-load 'haskell-cabal '(progn
  (define-key haskell-cabal-mode-map (kbd "C-`") 'haskell-interactive-bring)
  (define-key haskell-cabal-mode-map (kbd "C-c C-k") 'haskell-interactive-ode-clear)
  (define-key haskell-cabal-mode-map (kbd "C-c C-c") 'haskell-process-cabal-build)
  (define-key haskell-cabal-mode-map (kbd "C-c c") 'haskell-process-cabal)))

(custom-set-variables
 '(haskell-interactive-mode-hide-multi-line-errors nil)
 '(haskell-process-log t)
 '(haskell-process-type (quote cabal-repl)))

已添加

在Emacs中，自动完成显示“haskell-交互式-带来”功能是可用的。

然而，autoloading失败了。

Answer 1

问题是我有"haskell.el“来存储所有与haskell相关的配置设置。这导致了一些冲突，使得ELPA/haskell...包中的“ELPA/haskell...”无法正确加载。

当我把我的"haskell.el“改名为"haskell_config.el”时，一切似乎都很好。
