Some references to JS libraries could not be resolved - scala.js

Question

I am trying to follow the ScalaJS Book tutorial. Based on their build.sbt sample here https://github.com/ochrons/scalajs-spa-tutorial/blob/master/build.sbt
I have created the following build.sbt
lazy val client = (project in file("client"))
.settings(
name := "client",
version := "1.0.0",
scalaVersion := "2.12.4",
libraryDependencies ++= Seq(
"org.scala-js" %%% "scalajs-dom" % "0.9.4",
"com.lihaoyi" %%% "scalatags" % "0.6.7",
"com.vmunier" %% "scalajs-scripts" % "1.1.1",
"org.webjars" % "font-awesome" % "5.0.6" % Provided,
"org.webjars" % "bootstrap" % "4.0.0" % Provided,
"com.lihaoyi" %% "utest" % "0.6.3" % Test
),
jsDependencies ++= Seq(
"org.webjars.bower" % "react" % "16.1.0" / "react-with-addons.js" minified "react-with-addons.min.js" commonJSName "React",
"org.webjars.bower" % "react" % "16.1.0" / "react-dom.js" minified "react-dom.min.js" dependsOn "react-with-addons.js" commonJSName "ReactDOM",
"org.webjars" % "jquery" % "3.3.1" / "jquery.js" minified "jquery.min.js",
"org.webjars" % "bootstrap" % "4.0.0" / "bootstrap.js" minified "bootstrap.min.js" dependsOn "jquery.js",
"org.webjars" % "chartjs" % "2.7.0" / "Chart.js" minified "Chart.min.js",
"org.webjars" % "log4javascript" % "1.4.13" / "js/log4javascript_uncompressed.js" minified "js/log4javascript.js"
),
skip in packageJSDependencies := false,
scalaJSUseMainModuleInitializer := true,
scalaJSUseMainModuleInitializer in Test := false,
testFrameworks += new TestFramework("utest.runner.Framework")
).enablePlugins(ScalaJSPlugin).dependsOn(SharedJS)
But when I do sbt ~fastOptJS I get an error

Answer 1

Take a look at:
https://github.com/reactjs/react-bower
there is no
react-with-addons.js
package ...
There are other projects like https://scalacenter.github.io/scalajs-bundler/getting-started.html
besides you can manually include external JS sources via cdn:
