I would like to use Node-Red on my RaspberryPi B 3+ with GrovePi, but I get the same error message every time again and again.
[node-red-contrib-grovepi/grovepi] Error: Cannot find module 'i2c-bus'
i2c is enabled in the raspi-config and I have everything installed that I've read on Node-Red/RPI Configuration.
Thanks to all!

Check your IPv4 address with the ipconfig command
Open webpro/conf/app.conf and paste the IPv4 address into the http.addr parameter
Hi I have installed Kamalio it start first time but when I stop and start it again it gives sctp_core_destroy(): SCTP API not initialized . I have already installed sctp module.
yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg
load_module(): could not find module <db_mysql> in </usr/lib/kamailio/modules>
[sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized
From the log it is obvious that you have successfully compiled & installed SCTP module, however it could NOT be initialized.
Note that is error could must often than not be as a result of other errors in your cfg file.
Few tips:
Can you run kamailio -c and to be sure there is NO error in your cfg.
Found error? use this command to monitor what the exact issue is. Run from a different terminal tail -fn200 /var/log/syslog
On the second terminal try restarting you Kamalio server sudo service kamalio restart
Revisit terminal 1 and look out for the first line with CRITICAL output like the one below CRITICAL: <core> [core/cfg.y:3413]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 366, column 41: syntax error
Line 366 mostly is the issue so visit that file at that line (366) to fix the proble
sudo nano +366 /usr/local/etc/kamailio/kamailio.cfg
Let me know if it helps
Following the official guide of Titan DB here, and trying to run the command:
graph = TitanFactory.open('conf/titan-cassandra-es.properties')
I got this error:
Backend shorthand unknown: conf/titan-cassandra-es.properties
Obviously, the reason is the incorrect path to the
titan-cassandra-es.properties
file. So I changed it to:
graph = TitanFactory.open('../conf/titan-cassandra-es.properties')
and got this error:
Encountered unregistered class ID: 141.
The error happens in the following version:
titan-0.5.4-hadoop2
On titan-1.0.0-hadoop2 instead of this error message I get this one:
Invalid import definition: 'com.thinkaurelius.titan.hadoop.MapReduceIndexManagement'; reason: startup failed: script14747941661821834264593.groovy: 1: unable to resolve class com.thinkaurelius.titan.hadoop.MapReduceIndexManagement # line 1, column 1. import com.thinkaurelius.titan.hadoop.MapReduceIndexManagement ^
1 error
And on titan-1.0.0-hadoop2 I get this one:
The input line is too long.
The syntax of the command is incorrect.
Does anyone know how to handle this issue?
It seems like you have not even managed to get Titan 1 to start up yet.
I do not believe Titan 1 has been deployed to support Windows out of the box. I.e. the downloadable package will not just work with windows.
Saying that I have managed to get Titan DB 1 to work on windows. To do so, all you have to do is install Cassandra 2.x on Windows. This guide may help you out. Start cassandra and enable thrift connections.
With that done you should be able to get Titan doing basic operations on windows. From there you may find dealing with you current errors easier.
Side Note: Windows support for Titan 0.5.x may be more substantial. So you could look into that as well.
So I am new to veins and I am trying to learn how to use this framework. I started following this tutorial http://veins.car2x.org/tutorial/ I reached the last step and everything was working fine. In the last step and when i tried to run the veins example form omnetpp I got the following error :
<!> Error in module (Veins::TraCIScenarioManagerLaunchd)
RSUExampleScenario.manager (id=6) at event #1, t=0: Connection to

Can someone please help. I am a beginner and I am facing some problems,Thank you.
You have asked sumo-launchd.py to run SUMO as Sumo/bin/sumo.exe, but your system cannot find the file specified. Most likely, you need to run SUMO more like this /c/Users/user/src/sumo-0.25.0/bin/sumo.exe (depending on where you put sumo.exe)
I am trying to setup a network in the container (using Docker's libnetwork and libcontainer), but I keep running into this issue. As far as I can tell it's looking into some_app to get some sandbox information?

I was wondering if anyone could help me make sense of this and perhaps prevent it. Are these two separate errors?
Thank you
Here is the library I am trying to use
It took me a while to figure this out, but here goes:
Just like in Docker, libnetwork creates a veth interface pair. It then moves one end of the veth pair into the container namespace. During this process libnetwork tries to execute commands registered at runtime on the current instance of the binary (some_app in this case).
These commands do not exist on the external interface of some_app however. They are injected later using a library called reexec. For this to work, reexec needs to be initialized like this:
if reexec.Init() {
return
}
Also note that according to this thread libnetwork is currently not supported for applications outside of Docker.
NB: I discovered this by reading the source code, so I might be wrong but my issue went away after this.
