How to install jython 2.7?

Question

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?

Solution 1

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.

Ubuntu Artful (17.10) has jython version 2.7.1.

So just upgrade to that.

The Jython devs are geniuses but they don't keep things up-to-date: 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)
