Bash -安装Ocaml

Question

我正在尝试从命令行安装。我已经安装了使用Homebrew的Ocaml和OPAM (brew安装opam，brew安装ocaml)，但是当我进入时：

opam install ocaml-top

我得到了

[ERROR] No OPAM root found at /Users/student/.opam.

我需要把这个加到我的道路上吗？

更新:建议得到了帮助，但是包名有一个问题:我得到了

[ERROR] No package named ocaml-top found.

在运行opam init时，您似乎忽略了以下警告，特别是brew install opam

$ brew info opam
...
==> Caveats
OPAM uses ~/.opam by default for its package database, so you need to
initialize it first by running (as a normal user):

$  opam init

Run the following to initialize your environment variables:

$  eval `opam config env`

To export the needed variables every time, add them to your dotfiles.
  * On Bash, add them to `~/.bash_profile`.
  * On Zsh, add them to `~/.zprofile` or `~/.zshrc` instead.

Documentation and tutorials are available at https://opam.ocaml.org, or
via "man opam" and "opam --help".
