python-flask fails at runtime on Yocto/poky #138
Description
The flask application fails to start on poky. There are two methods of starting the main application:
root@qemux86-64:~# python -m flask run
Could not import runpy module
root@qemux86-64:~# flask run
Traceback (most recent call last):
File "/usr/bin/flask", line 6, in <module>
from pkg_resources import load_entry_point
ImportError: No module named pkg_resources
Python also fails to import the flask module:
>>> import flask
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/site-packages/flask/__init__.py", line 21, in <module>
from .app import Flask, Request, Response
File "/usr/lib/python2.7/site-packages/flask/app.py", line 35, in <module>
from .logging import create_logger
File "/usr/lib/python2.7/site-packages/flask/logging.py", line 12, in <module>
import logging
ImportError: No module named logging
I'm using the master branch of poky and meta-openembedded, both up-to-date when this issue was created. My local.conf file was generated by the oe-init-build-env script and has the following line appended:
IMAGE_INSTALL_append = " python-flask"
My bblayers.conf file:
# POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = "2"
BBPATH = "${TOPDIR}"
BBFILES ?= ""
BBLAYERS ?= " \
