ScalaJS中的链接器错误：“引用不存在的类”

Question

当我在一个Scala项目中尝试链接到FastParse时，我收到了一堆链接错误，我刚刚试图在这个项目中构建一个ScalaJS web应用。

我将FastParse的ScalaJS依赖项添加到我的build.sbt中:下面是相关行(完整文件here)：

libraryDependencies ++= Seq(
  "com.lihaoyi" %%% "fastparse" % "0.4.1"
)

我的错误很多，但这里有一个具有代表性的错误：

[error]   called from parsers.MainParser$$anonfun$impls$1.apply()fastparse.core.Parser

我做错了什么？

Answer 1

问题是，我的build.sbt中需要的是FastParse的JVM版本。这显然破坏了我的构建。我删除了这一行并清理了构建，现在项目的ScalaJS和ScalaJVM版本都可以很好地构建了。

(非常感谢李浩一为我发现了问题)
