OCaml 图形错误未绑定模块 mac OSX

Question

I'm on OSX 10.11.6 (and sometimes 10.13.6).我在 OSX 10.11.6（有时是 10.13.6）上。 I've done the following (per https://stackoverflow.com/a/29609483/2630028 ):我已经完成了以下操作（根据https://stackoverflow.com/a/29609483/2630028 ）：

brew install Caskroom/cask/xquartz
brew install ocaml
brew install pkg-config
brew install opam
opam install utop
opam install graphics

All commands are successful.所有命令都成功。 Unfortunately there is no longer a --with-x11 flag with the ocaml brew formula.不幸的是， ocaml brew 公式不再有--with-x11标志。 I tried to follow this doc: https://ocaml.org/learn/tutorials/structure_of_ocaml_programs.html#Modules-and-open .我试图遵循这个文档： https://ocaml.org/learn/tutorials/structure_of_ocaml_programs.html#Modules-and-open 。

In utop :在utop ：

utop # #load "graphics.cma";;
Cannot find file graphics.cma.

In a foo.ml file在 foo.ml 文件中

open Graphics;;

and running ocamlbuild foo.native :并运行ocamlbuild foo.native ：

File "foo.ml", line 1, characters 5-13:
1 | open Graphics;;
         ^^^^^^^^
Error: Unbound module Graphics
Command exited with code 2.

Is there any way to get this working without having to build from source?有没有办法让这个工作而不必从源代码构建？

Answer 1

Have you tried something like this?你有没有尝试过这样的事情？

utop -I $(ocamlfind query graphics)

It worked for me.它对我有用。 You may need to adapt the syntax to your shell (here bash ).您可能需要使语法适应您的 shell（此处为bash ）。
