[Jython-dev] Error running Jython3

[Patrick P. <psy...@gm...>]

I was able to find the Jython3 package on GitHub, so I coned the
reposaitory.

I built it with Ant like I did for Jython 2.7.2a1+ (seeing no other
instructions in the README file).  It reported a successful build. I am
using the openJDK-9 (well, my system says: javac 9-internal). Could that
be the reson? I've had no problems until now and works when building 2.7.2.

When I execute  ./jython, I get the following:

java.io.FileNotFoundException:
src/resources/frozen_importlib/_frozen_importlib.class (No such file or
directory)

Should I build with a different Java? I have JDK1.8.0_151 and OpenJDK-8
also.

My system is Ubuntu 16.04.

Hi Patrick,

That's my fault, I forgot to commit the "frozen" module, also the path is
hardcoded, but will handle that later.
Will let you know when I have a fix.

Regards,
Isaiah

The file is actually there, but since it uses relative path, you have to
execute the command with "dist/bin/jython". Hope it helps.

Re: [Jython-dev] Error running Jython3

[Jeff A. <ja...@fa...>]

Hi Isaiah.

Since that module stops Jython 3 running on Windows, it would be good to 
have a little account of how to build it from source. There's a section 
in the developer guide intended for that. 
(http://jython-devguide.readthedocs.io/en/jython/setup_jy.html#manually-regenerated-files)

Generally we'd like to reduce/eliminate checked in blobs, but that's a 
longer work.

Hi Jeff,

That's not the problem that affects windows, i think on windows it requires
the `winreg` module, which is not implemented.

The `_frozen_importlib` is not normal blobs, it's the equivalent of cpython
frozen module, which is the compiled code of the `importlib/_bootstrap` and
`importlib/_bootstrap_external`, it's need to bootstrap the import
machinery. The problem here is that it should use
ClassLoader.getResourceAsStream to read the class file instead of using a
hardcoded file reader.

Cheers,
Isaiah
