本文介绍如何安装Scala并配置环境变量，通过示例代码验证Scala环境是否安装成功。具体步骤包括安装JDK 5.0，设置.bashrc文件中的PATH环境变量，并运行Scala自带示例进行测试。
1. install jdk5.0
2. set env
vi .bashrc
export PATH=the path/scala-2.8.0.final/bin:$PATH
3. test
You may test the distribution by running the following commands:
$ sbaz install scala-devel-docs
$ scalac your path/doc/scala-devel-docs/examples/sort.scala
$ scala examples.sort
[6,2,8,5,1]
[1,2,5,6,8]
$ scala
scala> examples.sort.main(null)
[6,2,8,5,1]
[1,2,5,6,8]
scala>:quit
it's ok now
2. set env
vi .bashrc
export PATH=the path/scala-2.8.0.final/bin:$PATH
3. test
You may test the distribution by running the following commands:
$ sbaz install scala-devel-docs
$ scalac your path/doc/scala-devel-docs/examples/sort.scala
$ scala examples.sort
[6,2,8,5,1]
[1,2,5,6,8]
$ scala
scala> examples.sort.main(null)
[6,2,8,5,1]
[1,2,5,6,8]
scala>:quit
it's ok now
