The problem is using batteries

Format.err_formatter (Filename.concat (Findlib.package_directory
"batteries") "battop.ml");;
but when I launch ocaml
, I get this: 但是当我启动ocaml
,我得到了这个:
$ ocaml

Topfind.reset();; to force that packages will be reloaded
#thread;; to enable threads

What's the problem? 有什么问题?
Is there a reason why you're not using OPAM? 你有没有使用OPAM的原因? ( https://github.com/OCamlPro/opam ) ( https://github.com/OCamlPro/opam )
Install OPAM, switch to your favorite version of the 4.0x compiler (for example opam switch 4.00.1
), and run: opam install batteries
. 安装OPAM,切换到您最喜欢的4.0x版本编译器(例如opam switch 4.00.1
),然后运行: opam install batteries
。 I recommend doing opam install utop
and using utop
instead of the vanilla toplevel. 我建议使用opam install utop
并使用utop
而不是vanilla toplevel。 In either case: 在任一情况下:
Put the following in your ~/.ocamlinit
将以下内容放在~/.ocamlinit
#use "topfind";;
#require "batteries";;
open Batteries;;
This is all you need to get batteries working. 这就是让电池工作所需的一切。
