Question

After uncompressing web2py latest source on Linux Redhat 64bit (Python 2.7.3), I start the server and the first call generates this stack trace:

Anyone can help please?

Answer 1

This issue was related to sqlite3 missing from Python’s installation.

Recompiling Python with that library fixed the problem.
