The steps needed to install Scala on Ubuntu are slightly complicated, as you need the latest version of Scala (not the one that comes with Ubuntu). If you have already installed Scala, the instructions below will remove them and install the correct versions for you.
This is what you should do:
- Copy the BASH script below into a file called
install-scala.sh
- Open a command line.
cd
to wherever you storedinstall-scala.sh
- Make the script executable by executing the following command on the shell (remember you don't type in the
$
, that's the shell prompt!):
$ chmod +x install-scala.sh
- Run the script like this (you will be asked to enter your password):
$ ./install-scala.sh
- Check that Scala was installed properly, like this:
$ source ~/.bashrc $ scala Welcome to Scala version 2.9.1.final (Java HotSpot(TM) Server VM, Java 1.6.0_22). Type in expressions to have them evaluated. Type :help for more information. scala> // Press Ctrl+d to get out of this interpreter
- You should now have Scala version 2.9.1 correctly installed.
