我已经安装了opam，之后我可以成功访问ocaml,ocamlc, buildocaml。如何在ocaml中安装corebuild
但我正在阅读Real World OCaml这是要求我运行一个名为corebuild的工具。我不能安装（或运行）corebuild。
如果我搜索sudo find/-name corebuild...我可以看到文件，如
/home/abhishek/.opam/repo/default/packages/core/core.109.38.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.42.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.35.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.34.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.47.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.41.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.32.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.37.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.45.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.36.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.40.00/files/corebuild
但还是那么我不知道该如何运行此工具。
