How to install Scala on Mac OS
Recently i started learning Scala, since it's compatible with Java and allows you to write in a more functional way. At a first look i thought that it's Java where you can write in Python way, but it's just my first feeling. I've started a nice course on Coursera and looking forward to learn this language better. First step of studying any language or framework is to set it up on your working machine ( Hi Captain Obviousness:) ) So, there are at least 2 ways of installing scala on your mac :
- You can use homebrew installer.
- First, make sure you have Xcode installed (it’s free in the Mac App Store) with its optional command line tools installed (in Xcode go to Preferences, Downloads, and click “Install” next to Command Line Tools).
- Next, install Homebrew by running the following in a terminal:
ruby -e “$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)”
- Note : Note: The above command is changed by the Homebrew guys from time to time. If the above command doesn’t seem to be working, check the Homebrew website for the latest incantation: http://brew.sh/
- Follow the instructions and enter your system password when prompted. Once Homebrew is installed, it’s super easy to install Scala by typing the following in a terminal:
brew install scala
* Homebrew will install Scala in /usr/local
Or you can install it manually
- Download scala-X.XX.tgz from the official site.
- Unzip archive and move it to /usr/local folder
sudo cp -R scala-X.XX /usr/local/scala
- Open your .bash_profile file :
sudo nano ~/.bash_profile
- Add scala/bin folder to your PATH
- Save it and restart your terminal. Now you can check if scala works by simply typing
- If everything was setup correctly you should see this on your screen :
Welcome to Scala version 2.11.0 (Java HotSpot(TM) 64-Bit Server VM, Java 1.7.0_51).
