Macos 找不到_ocaml.ppx的js_,macos,ocaml,opam,js-of-ocaml,ocsigen,Macos,Ocaml,Opam,Js Of Ocaml,Ocsigen,我试图运行js_of_eliom，但它似乎没有ppx_派生这是我做make时得到的信息： js_of_eliom -ppx -c -package lwt -package js_of_ocaml.deriving -package js_of_ocaml.ppx simple_pomodoro.eliom Fatal error: exception Fl_package_base.No_such_package("js_of_ocaml.ppx", "") make: *** [_cli

我试图运行js_of_eliom，但它似乎没有ppx_派生这是我做make时得到的信息：

js_of_eliom -ppx -c -package lwt -package js_of_ocaml.deriving -package js_of_ocaml.ppx  simple_pomodoro.eliom
Fatal error: exception Fl_package_base.No_such_package("js_of_ocaml.ppx", "")
make: *** [_client/simple_pomodoro.cmo] Error 2

当我执行ocamlfind查询js_of_ocaml.ppx时，我得到了以下结果：

ocamlfind: Package `js_of_ocaml.ppx' not found

但我已经安装了ppx_，opam列表显示：

ppx_deriving           3.3  Type-driven code generation for OCaml >=4.02

我和el capitan一起在MacOSX上跑步（10.11）知道为什么会这样吗

编辑

哦，很抱歉，我还安装了js_of_ocaml，这是我的ocamlfind中显示的内容：

λ ~/ ocamlfind list | grep js_of_ocaml
js_of_ocaml         (version: 2.7)
js_of_ocaml.compiler (version: [distributed with js_of_ocaml])

ppx_派生

是一个驱动程序，它管理不同的派生程序。它本身并没有提供任何帮助。您需要安装

js\u of_ocaml

deriver，它是

js\u of_ocaml

包的一部分：

opam install js_of_ocaml

因此，您将拥有：

$ ocamlfind list | grep js_of_ocaml.ppx
js_of_ocaml.ppx     (version: [distributed with js_of_ocaml])
js_of_ocaml.ppx.internal (version: [distributed with js_of_ocaml])

ppx_派生
