web2py version:

2.16.1-stable+timestamp.2017.11.14.05.54.25 (Running on Rocket 1.2.6, Python 2.7.15)

any idea?

thanks and best regards,

found the culprit is on the python version (not affected by the pre installed os or conda), already tested in conda python version from 2.7.10 till 2.7.14 is running well, when using 2.7.15 (latest) is return an error above

step for tested in conda that running well

conda create -y -n python2714_test python=2.7.14

source activate python2714_test

python -V

python ~/python/web2py/web2py.py --nogui --no-banner -a a -i 0.0.0.0 -p 8000

cd

rm -rf ~/python/web2py/applications/test

cp -R ~/python/web2py/applications/welcome/ ~/python/web2py/applications/test

rsync -zavr ~/git/web2py/test ~/python/web2py/applications/

rsync -zavur ~/git/web2py/test ~/python/web2py/applications/

curl http://127.0.0.1:8000/test/install_demo

but still can't find solution for 2.7.15 version, any hint?
