Question

我有一个以前工作的Scala脚本，当我尝试在新PC上运行它时，编译失败。

所以我制作了简单的脚本进行测试：

#!/bin/sh
exec scala -J-Xmx2g "$0" "$@"
!#

println("test")

尝试运行它我得到了：

test.scala

看起来Scala正在编写我脚本附近的内容，但我不太清楚如何调试它并修复它。

Answer 1

我遇到了同样的问题，并通过升级到Scala 2.12.6来解决了这个问题：

sudo apt remove scala-library scala
wget www.scala-lang.org/files/archive/scala-2.12.6.deb
sudo dpkg -i scala-2.12.6.deb

Answer 2

通过为2.11.12版禁用fsc对我有用：

#!/usr/bin/env -S scala -nc

Answer 3

安装最新的scala 2.12.6 manualy（来自tar gz）现在一切正常，打印测试

Scala脚本不能在Ubuntu上运行
