Jython的安装教程

Basic Install

Jython 2.7.1 is distributed via an executable jar file installer. Afterdownloading it, either double click thejython_installer-2.7.1.jar or run java with the -jar option

java -jar jython_installer-2.7.1.jar

This will start the regular GUI installer on most systems, or aconsole installer on headless systems. To force the installer towork in headless mode invoke the installer as:

java -jar jython_installer-2.7.1.jar --console

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

Standalone mode

The standalone option does no caching and so avoids the startup overhead (most likely at the cost of some speed in calling Java classes, but I have not profiled it)

You can try it out by running the installer:

$ java -jar jython_installer-2.7.1.jar

then when you come to the "Installation type" page, select "Standalone".

The installation will generate a jython.jar with the Python standard library (/Lib) files included, which can be run as:

$ java -jar jython.jar

Of course you can run scripts just by calling them as you might expect:

$ java -jar jython.jar script.py

Or, add this file to the classpath of your application.

Installation options

You can get a list of installer options (to install Jython unattended, for example) by running:

$ java -jar jython_installer-2.7.1.jar --help
