安装ocamlfind（findlib），但从来没有可以在Mac中找到任何额外的软件包

Question

刚刚有一台新的Mac，Mountain Lion，我希望设置所有与ocaml相关的东西。

我用下面的命令：

opam switch 4.00.1 

opam install findlib 

opam install batteries 

所有安装成功没有错误。

但我不能使用batteries,bisect等。总是说package can't be found。

有什么想法？

我应该设置任何path什么的？

1. install homebrew

    ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)" 

2. Emacs for Mac OS X

3. Install tuareg-mode 

    http://forge.ocamlcore.org/forum/forum.php?forum_id=808 

    http://marmalade-repo.org/ 
    Add to your .emacs: (require 'package) (in home directory) 

    (add-to-list 'package-archives 
     '("marmalade" . 
      "http://marmalade-repo.org/packages/")) 
    (package-initialize) 

    M-x eval-buffer to evaluate it, and then do M-x package-refresh-contents to load in the package listing.\ 

    ** m-x list-packages ** 

    select tuareg package 

    click install 

4. Install OCaml, OPam, rlwrap

    opam switch 4.00.1 

    opam install batteries

    https://github.com/ocaml-batteries-team/batteries-included/blob/master/ocamlinit 

    Put the following in ~/.ocamlinit 

    #use "topfind";; 
    Toploop.use_silently 
      Format.err_formatter (Filename.concat (Findlib.package_directory 
      "batteries") "battop.ml");;

有你运行 “神奇” 命令来建立你的环境变量？

eval `opam config env`
