在更新版本的Html.app中替代MVCTodo

Question

我想更新榆树MVC Todo取代旧版本在elm-package.json中的新的。我的新elm-package.json是：

{
    "version": "2.0.0",
    "summary": "TodoMVC created with Elm and elm-html",
    "repository": "https://github.com/somenxavier/minuscule.git",
    "license": "BSD3",
    "source-directories": [
        "."
    ],
    "exposed-modules": [],
    "dependencies": {
        "elm-lang/core": "5.1.1 <= v < 6.0.0",
        "elm-lang/html": "2.0.0 <= v < 3.0.0",
        "elm-lang/dom": "1.1.1 <= v < 2.0.0",
        "elm-lang/virtual-dom": "2.0.4 <= v < 2.1.0",
        "elm-lang/navigation": "2.1.0 <= v < 2.2.0",
        "elm-community/string-extra": "1.4.0 <= v < 1.5.0"
    },
    "elm-version": "0.18.0 <= v < 0.19.0"
}

但是elm-reactor抱怨我

I cannot find module 'Html.App'. Module 'Todo' is trying to import it.

我知道html.app是已过时，但是如何在代码中替换它的引用呢？具体来说，如何替换这个

Html.App.map (\msg -> UpdateTask ( id, msg )) taskView

见更新Elm 0.18的文档。具体地说：

elm-lang/html将Html.App塌陷为Html。因此，您需要删除任何导入的Html.App导入，转而引用Html.program。

Html.App.map现在是Html.map。
