我是榆树的新人.看到一种允许你开发前端内容的函数式语言很有意思.现在,即使我很好地遵循这里描述的步骤,我仍然遇到模块问题.

代码是

module Main where

import Html exposing ( Html )
import Signal

main : Signal Html.Html
main = Html.text "This should work."
       |> Signal.constant

我以前elm-reactor -a='localhost'能够查看我的输出.但我收到一个错误,无法找到模块"HTML":

I cannot find find module 'Html'.

Module 'Main' is trying to import it.

Potential problems could be:
  * Misspelled the module name
  * Need to add a source directory or new dependency to elm-package.json

(注意双重"发现"嘿嘿)修复建议没有帮助我.或者可能是因为我无法正确理解.json文件的使用.

ELM-的package.json:

{
    "version": "1.0.0",
    "summary": "testing elm",
    "license": "BSD3",
    "source-directories": [
        ".",
        "./bin/"
    ], …
