sbt - 如何在 scalajs-react 项目中使用 sbt-scalajs 插件排除 javascript 依赖项？

Question

如何使用 sbt-scalajs 插件排除 scalajs 依赖？

我正在尝试导入以下库

"org.webjars.bower" % "react-bootstrap-datetimepicker" % "0.0.14" / "react-bootstrap-datetimepicker.js"

但是这个库正在下载我的项目中已经存在的其他依赖项(“react”和“react-bootstrap”)，并且我遇到了版本冲突。

我试过使用排除功能

"org.webjars.bower" % "react-bootstrap-datetimepicker" % "0.0.14" exclude ("org.webjars.bower", "react") 

但这不允许我将/“react-bootstrap-datetimepicker.js”附加到命令中。

我得到的异常(exception)是:

org.scalajs.core.tools.classpath.JSLibResolveException: Some references to JS libraries could not be resolved:
- Ambiguous reference to a JS library: react-bootstrap.js
  Possible paths found on the classpath:

exclude是 sbt 的一个特性 libraryDependencies ，并且不会在 jsDependencies 中复制.所以你不能声明 exclude直接在你身上 jsDependencies .但是，由于 jsDependencies建立在 libraryDependencies 之上，你可以通过结合两者来实现你想要的，加上一点重复的代码:

libraryDependencies +=
  "org.webjars.bower" % "react-bootstrap-datetimepicker" % "0.0.14" exclude ("org.webjars.bower", "react")
jsDependencies +=
  "org.webjars.bower" % "react-bootstrap-datetimepicker" % "0.0.14" / "react-bootstrap-datetimepicker.js"
