How do I install Jython 2.7?

thufir@doge:~$ jython --version
"my" variable $jythonHome masks earlier declaration in same scope at /usr/bin/jython line 15.
Jython 2.5.3
thufir@doge:~$ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.10
DISTRIB_CODENAME=yakkety
DISTRIB_DESCRIPTION="Ubuntu 16.10"

Is there perhaps a particular package which will install 2.7, or another repo?

To install Jython 2.7:

  • Download it from their official website

  • Double click the jython_installer-2.7.0.jar or run java -jar jython_installer-2.7.0.jar. For headless mode add --console.

The installer will then walk through a similar set of steps in graphical or console mode: showing the license, selecting an install directory and JVM and actually copying Jython to the filesystem. After this completes, Jython is installed in the directory you selected. Executing a script in the install directory, jython on Unix-like systems, will start up the Jython console, which can be used to dynamically explore Jython and the Java runtime, or to run Jython scripts.

  • The Jython devs are geniuses but they don't keep things up-to-date: https://github.com/jythontools/jython (--> "releases") is the best place to go for the latest version, at time of writing 2.7.2a (which you wouldn't know from the official website) – mike rodent Jan 25 '18 at 20:50

Ubuntu Artful (17.10) has jython version 2.7.1.

So just upgrade to that.
