try the following command sudo pip2 install pyyaml

There should be a requirements.txt to install needed python libs for this repo.

Robot Blockly is currently being rewritten using the latest Google Blockly base, so this repo should only be used for research purposes.

Hi, I have the same problem. when looking at the code, it seems it is due a mix of python2 and python3 codes. ROS kinetic is powered by Pyhton 2 on my machine.

I am not sure that it is the best solution but it is a workaround that works for me.

Steps :

Code that works for me: 

#!/usr/bin/env python
import SimpleHTTPServer
import SocketServer
import socket
import os
from rospkg import RosPack

rp = RosPack()
frontend_path = rp.get_path('turtlebot3_blockly')
frontend_path += '/frontend'

print("Changing serve path to: " + frontend_path)

os.chdir(frontend_path)

HOST = socket.gethostname()
PORT = 1036
address = ("",PORT)

Handler = SimpleHTTPServer.SimpleHTTPRequestHandler

httpd = SocketServer.TCPServer(address, Handler)

print("serving at port", PORT)
httpd.serve_forever()

Hi, gdherbom.

I follow your instructions and got an error about "no module: crab_msgs.msg" in turtlebot3_blockly_backend.py

After comment those line about the "crab_msgs.msg" :

from crab_msgs.msg import apm_imu

from crab_msgs.msg import BodyCommand

from crab_msgs.msg import BodyState

from crab_msgs.msg import GaitCommand

from crab_msgs.msg import LegIKRequest

from crab_msgs.msg import LegJointsState

from crab_msgs.msg import LegPositionState

from crab_msgs.msg import LegsJointsState

: It work!

Thanks a lot for your help.
