Установка ocamlfind.1.8.0 на macOS Sierra

Question

Я следую dev.realworldocaml.org , чтобы выучить OCaml. Я застрял при установке, где я не могу получить доступ к библиотеке ocamlfind.

Мой ocaml по умолчанию - 4.07.0, установленный через homebrew:

PrisBook: ~ prisc_000 $ список пивоваров ocaml

/ USR / местные / Подвал / OCaml / 4.07.0_1 / бен / OCaml

Опам - это опам V2:

PrisBook: ~ prisc_000 $ opam --version 2.0.0

Когда я пытаюсь установить opam install core utop, я получаю следующую ошибку.

> PrisBook:~ prisc_000$ opam switch
#  switch   compiler             description
→  default  ocaml-system.4.07.0  default
PrisBook:~ prisc_000$ opam install core utop

Я не совсем уверен, что здесь происходит, так как я новичок в этом. Как установить ocamlfind на Mac?

Спасибо.

Answer 1

Моя версия OCaml: The OCaml toplevel, version 4.07.0
Моя версия опама: 2.0.1

Я столкнулся с той же проблемой при установке ocamlfind 1.8.0. Это потому, что мой /usr/local/lib/ocaml/nat.cmi файл предназначен для более старой версии OCaml. Я удалил папку /usr/local/lib/ocaml и переустановил OCaml через homebrew. Тогда команда opam install core utop хорошо работает на моей стороне.

Answer 2

Может показаться, что ошибка возникает вокруг скрипта песочницы opam, работающего

Решение:

Решение, в данном случае, заключалось в том, чтобы перейти к usr/local/bin, где у меня были показаны некоторые предыдущие версии opam и opam v2. Я вручную удалил все опам. Затем я запустил brew remove camlp4 ocamlbuild ocaml, чтобы opam видел только изолированную версию компилятора ocaml. Я удалил каталог ~ / .opam, а затем переустановил его из git через wget https://raw.github.com/ocaml/opam/master/shell/install.sh потому что opam v2 еще не доступен на homebrew, который устанавливает opam 1.2.

Затем я запустил opam install core utop, и ocamlbuild 1.8.0 успешно установлен.

Примечание: эта установка не сломала мои проекты mindml.
