如何在ocaml中安装corebuild

我已经安装opam,并在此之后,我可以访问ocaml,ocamlc,buildocaml成功.

但我正在阅读Real World OCaml,它要求我运行一个名为的工具corebuild.

我无法安装(或运行)corebuild.

如果我搜索sudo find / -name corebuild...我可以看到像这样的文件

/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  

但是,我仍然不知道如何运行这个工具.
