Question

我正在尝试建立basic Scala.js tutorial，并且遇到了这个奇怪的错误。

与教程中显示的项目设置没有太大区别，但以防万一我的build.sbt：

enablePlugins(ScalaJSPlugin)

scalaVersion := "2.12.1"

name := "algorithms1_4_34"
version := "1.0"

libraryDependencies ++= Seq("org.scalatest" % "scalatest_2.12" % "3.0.1" % "test",
            "org.scalacheck" %% "scalacheck" % "1.13.4" % "test",
             "org.scala-js" % "scalajs-dom_sjs0.6_2.12" % "0.9.1",
             "be.doeraene" %%% "scalajs-jquery" % "0.9.1")

// This is an application with a main method
scalaJSUseMainModuleInitializer := true

skip in packageJSDependencies := false
jsDependencies +=
  "org.webjars" % "jquery" % "2.1.4" / "2.1.4/jquery.js"
jsDependencies += RuntimeDOM

...和JSApp文件：

package ca.vgorcinschi.algorithms1_4_34

import scala.scalajs.js.JSApp
import org.scalajs.jquery.jQuery

object HotAndColdJS extends JSApp{

   def main(): Unit = {
     jQuery(()=>setupUI())
  }

  def addClickedMessage():Unit ={
    jQuery("body").append("<p>You clicked the button!</p>")
  }

  def setupUI():Unit = {
    //click envokes an event handler
    jQuery("#click-me-button").click(()=> addClickedMessage())
    jQuery("body").append("<p>Hello World!</p>")
  }
}

我可以毫无问题地运行compile，fastOptJS，reload和eclipse（我正在使用eclipsePlugin）命令。唯一的问题是run命令。为了公平起见，我确实在本教程的流程中添加了一些内容，但仅仅是因为从应用程序的根目录运行此命令（npm install jsdom）导致run中的失败（npm WARN enoent ENOENT）。按照建议here进行此操作后，我跑了：

npm init
npm install
npm install jsdom

这就是我现在所处的位置。这是使用run运行应用时遇到的错误：

如果有人能帮我一把，我将不胜感激。

Answer 1

jsdom v10引入了一些重大改变。 v9和Scala.js＆lt; = 0.6.15没有为那些人准备。这就是导致您遇到错误的原因。

升级到Scala.js 0.6.16将解决您的问题。它支持jsdom v9和v10。

TypeError：jsdom.createVirtualConsole不是函数
