It looks like Jinja2 has an optional "speedups" module that Jython is choking on:
http://bitbucket.org/mitsuhiko/jinja2-main/src/tip/setup.py You might try checking Jinja2 out from bitbucket, commenting out the "features" stanza in its setup.py and installing it into your virtualenv (if you're using one; otherwise just globally) by hand (jython setup.py install I guess) before trying to install repoze.bfg.jinja2. I suspect it might work after that. Yes, the "parser" module is related to the "ast" module (doesn't seem to be supported on non-CPython platforms). - C Diaz, Eduardo wrote: > Ok, I'm going to give it a try in a while for now, this is the problem > with jinja2, it needs to compile something > > easy_install -i http://dist.repoze.org/bfg/1.1/simple/ repoze.bfg.jinja2 > Searching for repoze.bfg.jinja2 > Best match: repoze.bfg.jinja2 0.5 > Processing repoze.bfg.jinja2-0.5-py2.5.egg > repoze.bfg.jinja2 0.5 is already the active version in easy-install.pth > > Using > /home/iamedu/Tests/jython/sys/Lib/site-packages/repoze.bfg.jinja2-0.5-py2.5.egg > Processing dependencies for repoze.bfg.jinja2 > Searching for Jinja2 > Reading http://dist.repoze.org/bfg/1.1/simple/Jinja2/ > Best match: Jinja2 2.1.1 > Downloading http://dist.repoze.org/bfg/1.1/Jinja2-2.1.1.tar.gz > Processing Jinja2-2.1.1.tar.gz > Running Jinja2-2.1.1/setup.py -q bdist_egg --dist-dir > /tmp/easy_install-wxGcPq/Jinja2-2.1.1/egg-dist-tmp-eTzSIB > warning: no files found matching 'Makefile' > warning: no files found matching 'ez_setup.py' > warning: no previously-included files matching '*' found under directory > 'docs/_build/doctrees' > error: Setup script exited with error: Compiling extensions is not > supported on Jython > > The problem with chameleon is that jython doesn't have the parser module. > > Going to keep checking with other templating engines. > > On Mon, Jan 4, 2010 at 4:10 PM, Chris McDonough <chr...@plope.com > <mailto:chr...@plope.com>> wrote: > > Diaz, Eduardo wrote: > > That helps with the zcml problem but now, there is a problem > with chameleon, is there another template language I can use?
