导入库的Scala问题

  • 772

我想导入这个。build.sbt文件的内容

name := "abdesante"

version := "0.1"

scalaVersion := "2.13.3"
libraryDependencies += "com.bot4s" %% "telegram-core" % "4.4.0-RC2"

这是 sbt 的输出：

我究竟做错了什么？除了写台词libaryDependencies，什么都没做。这可能是因为它是 2.12 的，但它的成本是 2.13？

    是的，你的假设是正确的。这个适用于Scala 2.11 和 2.12。

    该存储库有一个关于 Scala 2.13 的未解决问题。作为您的问题的解决方案 - 使用 Scala 2.12。

    `%%` 操作符表示项目中安装的rock的版本会被添加到依赖的名字中。在您的情况下，这两行完全相同： 
    libraryDependencies += "com.bot4s" %% "telegram-core"      % "4.4.0-RC2"
libraryDependencies += "com.bot4s" %  "telegram-core_2.13" % "4.4.0-RC2"
