flask error

[rvipin17]

if I do roslaunch rostful rostful.launch, getting following error:

File "/home/addverb/.environments/mir/local/lib/python2.7/site-packages/flask/__init__.py", line 21, in <module> from .app import Flask, Request, Response File "/home/addverb/.environments/mir/local/lib/python2.7/site-packages/flask/app.py", line 25, in <module> from . import cli, json File "/home/addverb/.environments/mir/local/lib/python2.7/site-packages/flask/cli.py", line 39, in <module> class NoAppException(click.UsageError): AttributeError: 'module' object has no attribute 'UsageError' [rostful-2] process has died [pid 9754, exit code 1, cmd /home/addverb/catkin_mir_ws/src/rostful/scripts/rostful -h 127.0.0.1 -p 8080 -s flask -c /home/addverb/catkin_mir_ws/src/rostful/instance/rostful.cfg -l /home/addverb/catkin_mir_ws/src/rostful/instance/rostful.log ~connections_list:=/connection_cache/list ~connections_diff:=/connection_cache/diff __name:=rostful __log:=/home/addverb/.ros/log/9dec2b6a-cd19-11e8-996d-dca26629e16b/rostful-2.log]. log file: /home/addverb/.ros/log/9dec2b6a-cd19-11e8-996d-dca26629e16b/rostful-2*.log
Also, if we create a virtual environment and run python -m rostful flask

I am getting the following error message:

How about verbose python option ? it should let you know what happened and what breaks.

I was able to solve this issue by installing all the deps. Thanks

Rostful install:

Navigate to your workspace,
$ cd ~/catkin_ws/src
$ git clone -b gopher-devel --recursive https://github.com/pyros-dev/rostful.git
$ cd rostful
$ cd deps
$ git clone --recursive https://github.com/pyros-dev/pyros-utils.git
$ cd pyros-utils
$ pip install .
$ cd ..
$ git clone --recursive https://github.com/pyros-dev/pyros.git
$ cd pyros
$ pip install .
$ cd ../..
$ pip install .
$ pip install -r requirements.txt
$ cd ../..
$ catkin_make
$ source devel/setup.bash
$ roslaunch rostful rostful.launch

The above steps will solve all dependencies with rostful. Browse to localhost:8080, you’ll be able to see your rostful localhost running.

Correct me if I am wrong

So there are a few different ways to do this... - You could clone everything ( even all the ros source ) and build everything together. - You could download packages from ros instead for things you are not interested in modifying/rebuilding. - You could run directly from a python setup with a virtualenv, and use pyros-setup to discover your ros distro dynamically on runtime. Or any combination of these. But you need to understand how your system works, how ros setup.bash modify your environment, how python expect his environment, and how pyros-setup can find ros distro by modifying your python runtime, and not your whole system (like ros does).

Hi,
In case it might help, I have updated a rostful usecase with turtlesim : asmodehn/rostful-examples#6
Let me know if you find it useful.
Thanks.
