Cygwin 中的 Opam 与 Windows emacs

Question

我在Cygwin中成功安装了https://github.com/fdopen/opam-repository-mingw、merlin和tuareg。现在我已经安装了 Windows emacs 并更改了 .emacs 以启用模式来编辑 Ocaml 文件。

设置应该是这样的吗？ Windows emacs 可以像这样使用 Cygwin OCaml 工具吗？

如果没有，那么我要求提供在 Cygwin 中设置 emacs 的详细信息。

更新：现在我的init.el是这个

;; Added by Package.el.  This must come before configurations of
;; installed packages.  Don't delete this line.  If you don't want it,
;; just comment it out by adding a semicolon to the start of the line.
;; You may delete these explanatory comments.
(package-initialize)

(setenv "PATH" (concat "c:/OCaml64/bin;" (getenv "PATH")))
(setq exec-path (cons "c:/OCaml64/bin/" exec-path))
(require 'cygwin-mount)
(cygwin-mount-activate)

(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.

cygwin-mount.el 在 site-lisp 文件夹中。

打开 .ml 文件或键入 M-x merlin-mode 时我没有看到任何变化

您确定 Tuareg 确实已加载吗？如果你转到*scratch*，键入(locate-library "tuareg")并执行它（当光标在右大括号之后时键入C-xC-e），你会在回显区域看到什么？

在你安装图阿雷格人的目录下，应该有一个文件tuareg-site-file.el。如果是这样，请输入您的 ~/.emacs，行： (load "/path/to/tuareg-site-file") 启用图阿雷格语。
