Elm 0.17中的图像
我正在尝试一个带有单个图像的测试示例:Elm 0.17中的图像,elm,Elm,我正在尝试一个带有单个图像的测试示例: import Html exposing (Html) import Graphics.Element main = image 960 500 "starry-night.jpg" 我正在用elm反应堆进行试验,但这个简单的结果无法编译: I cannot find module 'Graphics.Element'. Module 'Main' is trying to import it. Potential problems could be
import Html exposing (Html)
import Graphics.Element
main = image 960 500 "starry-night.jpg"
我正在用elm反应堆进行试验,但这个简单的结果无法编译:
I cannot find module 'Graphics.Element'.
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
我试着导入必要的grahics软件包
模块的名称是
Element
,而不是Graphics.Element
,因此编译器无法找到它
此外,image
函数返回一个元素
,而main
函数需要Html
类型的内容
程序的运行版本可能类似于
导入元素公开(…)
主要=
toHtml(图片960500“StarryNight.jpg”)
