Configure Scala language development environment on Mac

Configure Scala language development environment on Mac

1. Install JDK

Scala is a language based on the Java platform, so you need to install JDK (Java Development Kit) first.
You can download and install JDK from Oracle's official website, or use Homebrew to install JDK.

Execute the following command in the terminal to install JDK using Homebrew:

brew install openjdk@8

2. Install Scala

After installing the JDK, you can use Homebrew to install Scala. Execute the following command in the terminal:

brew install scala

After the installation is complete, you can check whether the Scala version is correct with the following command:

scala -version

3. Install SBT

SBT (Scala Build Tool) is a build tool for Scala projects. You can use Homebrew to install SBT, or you can download and install it from the SBT official website.

You can install SBT using Homebrew by executing the following command in Terminal:

brew install sbt

4. Write and run Scala code

After installing Scala and SBT, you can use any text editor to write Scala code. For example, a Scala file can be opened with the Vim editor:

vim HelloWorld.scala

Enter the following code in the editor:

object HelloWorld {
    
    
  def main(args: Array[String]): Unit = {
    
    
    println("Hello, world!")
  }
}

After saving the file, the Scala code can be run using SBT:

sbt run

This command will automatically compile and run HelloWorld.scalathe code in and output "Hello, world!".

The above is a common way to configure the Scala language development environment on Mac. This way can not only install Scala and SBT, but also install and manage other development environments and tools. If you need more complex Scala language development, you may need to install other development environments and tools.
