説明
A major issue is that the json module is broken for python-light on OpenWrt. The module won't work without another system package called python-codecs.
As an alternative Python package, python-base on OpenWrt provides a much smaller subset of the Python standard library than python-light. Modules like atexit, tarfile, time, binascii, and even __future__ are all unavailable.
These modules are all imported without checking their existence.
