我正在尝试让 intero运行。安装后，从现有堆栈项目中打开 Haskell 文件会导致：

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  signal(wrong-type-argument (stringp nil))
  flycheck-buffer()
  flycheck-buffer-automatically()
  flycheck-perform-deferred-syntax-check()
  set-window-buffer(#<window 1 on Lib.hs> #<buffer Lib.hs>)
  window--display-buffer(#<buffer Lib.hs> #<window 1 on Lib.hs> reuse ((inhibit-same-window)))
  display-buffer-same-window(#<buffer Lib.hs> ((inhibit-same-window)))
  display-buffer(#<buffer Lib.hs> (display-buffer-same-window (inhibit-same-window)))
  pop-to-buffer(#<buffer Lib.hs> (display-buffer-same-window (inhibit-same-window)) nil)
  pop-to-buffer-same-window(#<buffer Lib.hs>)
  find-file("~/test/src/Lib.hs" t)
  funcall-interactively(find-file "~/test/src/Lib.hs" t)
  call-interactively(find-file nil nil)
  command-execute(find-file)

当我flycheck-buffer在同一个缓冲区中运行时，即使源代码中有错误，也没有任何反应。

这是我的.emacs文件的内容：

(setq debug-on-error t)

(require 'package)
(add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/") t)
(package-initialize)
(package-refresh-contents)

(package-install 'intero)
(add-hook 'haskell-mode-hook 'intero-mode)

由于我在 Mac …
