I'm not a member of this community but happen to be lurking here and the issue you paste is not complex.
Is this question on-topic for this list, or would it better go in a python or jinja help community?
although I run
pip install jinja2.ext
It looks like you might be trying to build without reading the README. `pip3 install jinja2` works for me.
line 911, in main
It looks like your config resulted in the makefile using python2. The README says that python3 is required. I don't know if that's the cause of your issue, but it's a present issue.
You can test your jinja setup with:
pip3 install jinja2
>> import jinja2.ext
Myself, when I try to build the website, I have a different issue:
~/src/www $ ./bootstrap
Synchronizing submodule url for 'build-system/taler-build-scripts'
Synchronizing submodule url for 'inc'
~/src/www $ ./configure
info: running with python sys.version_info(major=3, minor=9, micro=6, releaselevel='final', serial=0)
required option '--variant' missing
Curious if others have the --variant problem, but I understand that this isn't a support list.
