查看此SO post,我尝试将以下代码粘贴到Putty和Windows命令行中。
def size(root: Leaf, left: Branch, right: Branch) : Int = {
def go(branch: Branch, acc: Int) : Int = branch match {
case Nil => acc
case branch.left != Nil && branch.right != Nil => go(branch.left, acc) +
go(branch.right, acc)
case branch.left != Nil => go(branch.left, acc)
case branch.right != Nil => go(branch.right, acc)
case _ => 0
}
root match {
case Nil => go(left, 0) + go(right, 0)
case _ => 1 + go(left, 0) + go(right, 0)
}
}
然而,即使我只是粘贴到Putty和Windows 7命令行,以下输出:

由于我认为,当我尝试粘贴时,这种意外的输出行为不会编译。

检查那里是否有TAB字符。按TAB键时,sbt会触发代码完成。它也以粘贴模式运行。所以它可能试图完成你的陈述并完成错误。
