PyKE on IronPython

[Bill Janssen]

I found myself wanting to run PyKE on IronPython. Turned out to be
almost easy.

One problem with IP 2.7 is that it doesn't have the subprocess
module. So I had to move the "import subprocess" in pyke/special.py
further into the code. I'd post the patch, but this durn bulletin
board doesn't seem to have the necessary non-line-wrapping markup.

So, I'm finally actually working on this, and it's my first non-trivial excursion into PyKE, Python, .NET and (forward chaining) IronPython.

I'm trying to avoid creating a dependency on .NET 4, so I want to use IronPython 2.6.  I downloaded PyKE 1.1.1 and tried following the yellow brick road, it did the "build" thing OK but then failed in "install".  I tried commenting out the import subprocess line but it didn't help

Error messages below.  Any ideas?

Stephen,

Not sure what the problem is that you're having.  It looks like an IronPython issue.  Pyke encountered errors in IronPython that were reported Dec 2008 as item# 20143 to the ironpython project.  This was reported fixed in Ironpython 2.6.1 in Feb 2010.  So I would be sure that you are using 2.6.1 or later of IronPython.  But that bug was different than this one.

Bill apparently didn't have this problem, so wondering if there is some other problem with ironpython 2.6?  This would be a question for the ironpython folks.  I don't have a windows box to play with ironpython.
