无法在Mac上安装sbt

嗨，我一直在尝试按照http://www.scala-sbt.org/0.13/tutorial/Manual-Installation.html上的说明在Mac上安装SBT 。

但是我被困在第一步：

将sbt-launch.jar放入〜/ bin。

我想我已经将sbt放入bin中了

然后我尝试通过brew安装它，安装过程顺利。但是然后当我检查sbt版本以确认安装时。我收到新的错误消息：

vtmbpr:~ VT$ brew install sbt

already exists. You may want to remove it:
  rm '/usr/local/bin/sbt'

To force the link and overwrite all conflicting files:
  brew link --overwrite sbt

To list all files that would be deleted:
  brew link --overwrite --dry-run sbt

Possible conflicting files are:
/usr/local/bin/sbt
==> Caveats
You can use $SBT_OPTS to pass additional JVM options to SBT:
   SBT_OPTS="-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256M"

This formula is now using the standard typesafe sbt launcher script.
Project specific options should be placed in .sbtopts in the root of your project.
Global settings should be placed in /usr/local/etc/sbtopts

对于每个人来说，这可能是一个非常简单的问题，但令人难以置信的是，他们陷入了长达3个小时的Coursera课程的“获取我的工具设置”阶段。

更新以删除并通过brew重新安装。之后如何判断sbt是否正常运行？我尝试运行sbt --version，但引发了一系列错误。
