Here is updated code. Note, it assumes the web2py folder is at the top
level within the home directory of the current user (you can change that
back to the old behavior if desired). It also allows you to have multiple
versions in different folders, such as "/web2py-2.15", "web2py-master", etc.
The new code updates some of the global_settings -- including the web2py
version, which is causing the error you see.
import os
import sys
import xml.dom.minidom as xml
from IPython.core.magic import register_line_magic
from IPython.core import display

def w2p(line):
'''
`line` is of the form: app[/controller] [web2py_version], where
controller
and web2py_version are optional, and web2py_version is the folder suffix
(excluding the hyphen) identifying the version (e.g., "2.15", "dev",
etc.).
'''
line = 'test/default' if not line else line.encode('ascii')
line = line.split(' ')
# Add the web2py path to the Python search path.
web2py_path = os.path.join(os.path.expanduser('~'), 'web2py')
if len(line) > 1:
web2py_path += '-%s' % line[1]
sys.path.insert(1, web2py_path) # Ensure web2py is early in the search
path.

# Update global_settings.
global_settings.gluon_parent = global_settings.applications_parent =
web2py_path
global_settings.cmd_options = Storage(shell=True) # for code that tests
for shell
with open(os.path.join(web2py_path, 'VERSION'), 'rb') as version_info:
global_settings.web2py_version = version_info.read().split()[-1].
strip()
