安装 elm-html 时 Elm 'hello world' 示例失败

Question

尝试使用 Elm 0.17 的 hello world 示例

-- Main.elm

import Html exposing (text)

main =
  text "Hello, World!"

justin@justin-ThinkPad-X240:~/work/hello_world_elm$ elm make Main.elm --output=index.html
Some new packages are needed. Here is the upgrade plan.

  Install:
    elm-lang/core 4.0.0

Do you approve of this plan? (y/n) y
Downloading elm-lang/core
Packages configured successfully!
I cannot 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
justin@justin-ThinkPad-X240:~/work/hello_world_elm$ elm package install evancz/elm-html
To install evancz/elm-html I would like to add the following
dependency to elm-package.json:

    "evancz/elm-html": "4.0.2 <= v < 5.0.0"

May I add that to elm-package.json for you? (y/n) y

知道我可能做错了什么吗？ Ubuntu 14.04，从 npm 安装的 Elm 0.17

谢谢！

软件包 evancz/elm-html 已被版本 0.17 中的 elm-lang/html 替换。所以你应该安装它。
