Question

刚买了一台新的Mac，Mountain Lion，我希望能够设置所有与ocaml相关的东西。

我使用了以下命令：

opam switch 4.00.1

opam install findlib

opam install batteries

所有安装均成功且没有错误。

但我无法使用batteries，bisect等。总是说package can't be found。

有什么想法吗？

我应该设置path还是其他什么？

让你运行“魔术”命令来设置你的环境变量吗？

eval `opam config env`

安装了ocamlfind（findlib），但在Mac上永远找不到任何额外的包
