Bash

Question

我正在尝试从命令行安装 Ocaml-Top IDE。我已经使用 Homebrew 安装了 Ocaml 和 OPAM（brew install opam，brew install ocaml），但是当我输入：

opam install ocaml-top

我明白了

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

我需要将它添加到我的 PATH 中吗？

更新：建议有帮助，但包名有问题：我得到

[ERROR] No package named ocaml-top found.

您似乎错过了以下警告，特别是 opam init，当您运行 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".
