linux 安装scala

1. 下载scala

到scala官网下载scala https://www.scala-lang.org/download/，目前最新版本是2.12.8

wget https://downloads.lightbend.com/scala/2.12.8/scala-2.12.8.tgz  #download scala binary file
mkdir /usr/local/scala   #create folder to put the unzipped scala file into
tar -xvzf scala-2.12..tgz && mv scala-2.12. /usr/local/scala/   #unzip scala binary file and move to the /usr/local/scala

2. 配置环境变量

vim /etc/profile   #add scala info to enviroment file.

在文件末尾添加以下内容

#scala
export SCALA_HOME=/usr/local/scala/scala-2.12.
export PATH=$SCALA_HOME/bin:$PATH

:wq保存退出

3. 使环境变量生效

source /etc/profil

4. 控制台输入scala -version

lenmom@M1701:~/workspace$ scala -version
Scala code runner version 2.12. -- Copyright -, LAMP/EPFL and Lightbend, Inc.
