Question

在OS X下，OCaml工作正常，但在Linux（Ubuntu 14.04 LTS）下，它返回以下错误：

zsh-5.0% ocaml
        OCaml version 4.02.1

Findlib has been successfully loaded. Additional directives:
  #require "package";;      to load a package
  #list;;                   to list the available packages
  #camlp4o;;                to load camlp4 (standard syntax)
  #camlp4r;;                to load camlp4 (revised syntax)
  #predicates "p,q,...";;   to set these predicates
  Topfind.reset();;         to force that packages will be reloaded
  #thread;;                 to enable threads

No such package: core.top
No such package: core.syntax
File ".ocamlinit", line 13, characters 5-13:
Error: Unbound module Core

这些行应突出显示：

No such package: core.top
No such package: core.syntax

有什么想法吗？

根据卡卡杜的要求，这是我的.ocamlinit：

zsh-5.0% cat .ocamlinit 
(* Added by OPAM. *)
let () =
  try Topdirs.dir_directory (Sys.getenv "OCAML_TOPLEVEL_PATH")
  with Not_found -> ()
;;

#use "topfind";;
#camlp4o;;
#thread;;
#require "core.top";;
#require "core.syntax";;

open Core.Std;;

query core的输出是：

zsh-5.0% ocamlfind query core
ocamlfind: Package `core' not found

更新

尝试安装core（OCaml 4.02.1）：

zsh-5.0% opam install core

Answer 1

这显然是一些环境问题。我已经在新的Ubuntu 14.04上安装了OPAM，一切都很好。

Answer 2

首先，如果你真的不需要核心库，那么你可以从.ocamlinit文件中删除这一行：

#camlp4o;;
#thread;;
#require "core.top";;
#require "core.syntax";;

open Core.Std;;

然后一切都会正常。

下一个问题是安装。它看起来像oasis包的一个严重问题，它是许多软件包使用的最流行的工具之一。所以这个问题可能会再次发生，最好能够治愈它。我建议你尝试以下方法：

确保您的opam环境已正确激活。你的shell的rc脚本通常会这样做，但是输入并不难，
```
eval `opam config env`
opam install core
```
尝试将oasis固定到最新版本（可能由于某种原因，您有一个不起作用的旧版oasis（这仍然是oasis中的一个问题包，应该报告和修复）。固定后，你需要尝试再次安装核心：
```
 opam pin add oasis 0.4.5
 opam install core
```
如果您在上一点失败，请尝试安装ocaml编译器的最新版本（至2016年2月）
```
 opam init --comp 4.02.3
 eval `opam config env`
 opam install core
```

未绑定模块核心
