Groom your app's Scala environment with scalaenv like rbenv :) Support offered for all official versions, including dotty and scala3.

Do you need sbt version management? Please refer to sbtenv in the case of use sbt.

1. git clone scalaenv into ~/.scalaenv.

   $ git clone git://github.com/scalaenv/scalaenv.git ~/.scalaenv

2. Add ~/.scalaenv/bin to your $PATH for access to the scalaenv command.

   $ echo 'export PATH="${HOME}/.scalaenv/bin:${PATH}"' >> ~/.zshrc

3. Add scalaenv init to your shell to enable shims and autocompletion.

   $ echo 'eval "$(scalaenv init -)"' >> ~/.zshrc

   Bash note: Modify your ~/.bash_profile file instead of ~/.zshrc.

4. Restart your shell so that PATH changes take effect. (Opening a new terminal tab will usually do it.) Now check if scalaenv was set up:

   $ type scalaenv
   #=> "scalaenv is a shell function"

   Same as in previous step, use ~/.bash_profile for Bash.

5. Install each version of scala.

   $ scalaenv install scala-2.13.4

   If show all available version, please use the following command:

   $ scalaenv install -l
   All available versions:
     scala-2.13.1
     scala-2.13.2
     scala-2.13.3
     scala-2.13.4
     ...

   If want to install manually, please download scala archive and extract into ~/.scalaenv/versions/.

   $ curl -LO http://www.scala-lang.org/files/archive/scala-2.13.4.tgz
   $ tar xf scala-2.13.4.tgz -C ~/.scalaenv/versions/

As an alternative to installation via GitHub checkout, you can install scalaenv using the Homebrew package manager on macOS.

$ brew update
$ brew install scalaenv

Or, if you would like to install the latest development release:

$ brew install --HEAD scalaenv

To upgrade HEAD package use --fetch-HEAD option:

$ brew upgrade --fetch-HEAD scalaenv
