I have installed KrakenJs on Windows 7. I have created project by using following command :
Yo Kraken
When I tried to run the project, it is giving following error (even after restarting system) :
E:\nodejs\test\kraken\Dust-01>npm start

Can some one guide me what I am doing wrong and how it can be rectified
Look into next two possibilities:
Try opening your command prompt 'As Administrator', that shall solve the issue if you are lacking permissions to open port.
Temporarily change the port used in Kraken to something irregular and long, example: 32482
Then move on from this, if 1st - then you have solved an issue, if 2nd - you are very likely trying to open a port, which is already used by other application.

I'm using the plugin gulp-server-livereload.
var server = require('gulp-server-livereload');
gulp.src(pathDir).pipe(server({
livereload: true,
directoryListing: true,
open: true,
port: 80
}));
How to stop the server?
I tried server.restart(), server.kill(), server.reset()
But always there are such errors:
Uncaught Error: listen EADDRINUSE 127.0.0.1:35729

at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:81:1

Please help me to solve my question or tell me another option how you can
implement what I need.
This error is occurring because of another process using the port. It is likely just a previous instance of this process, however it is possible that another application is using the port.
You will be unable to stop this using Node, as it is a process remaining from another run and processes do not have the permissions to 'manage' one another.
On Windows use task manager to kill the node process, on Mac you can use Activity Monitor, and on Unix/Linux you can use htop or similar.
Alternatively on Unix/Linux (incl. MacOS) you can use
sudo lsof -i :35729
to find the process id of the process ID using that port, then kill it:
kill -9 {PID}
To ensure your node server cleanly shuts down in future add event handlers:
process.on('SIGTERM', ..)
process.on('uncaughtException', ..)
and invoke code inside these to shut down your application.
500 Internal Server Error for URL:http://localhost:8100/api/timeline dev4living/HeyCommunity

-What should i do to fix this error?
-Your assistance will be very much appreciated.
The error states that the port you are trying to use is already occupied. Please check the app running in the port 8100 and stop that and try to run the app again. Changing the port number to something else apart from 8100 will also solve the problem.
The error is pretty self-explanatory buddy. It just means that the address you have used, i.e, the port number is currently in use by something else.
2 possible solutions:
Simply change the port number
using cmd to get the list of processes running. Identify the process running on that port. And use taskkill -pid command. Refer this stack overflow post for details regarding this method
I have problem with creating basic sails.js application on Cloud9 environment and connecting it to MySQL.
Steps I'm making:
Creating Cloud9 project
installing sails: npm -g install sails
creating project: sails new test
lifting: cd testProject/ and sails lift
Here it's working
Adding mySQL support: mysql-ctl start
still working
adding phpMyAdmin support: phpmyadmin-ctl install
And here, my application stops working. I'm getting exception:

Additionally I'm getting info about problem with starting my app, and ability to kill the process. Of course killing does not help.
Could youplease help me with that?
So what's happening is that you're starting your sails server, which binds to port 8080, and then you try to install phpmyadmin which tries to start apache (at port 8080 too!) causing it to actually fail since the port is already in use. You will have to stop sails before trying to install / run phpmyadmin since two servers can't listen on the same port.
I am trying to use the mean stack as described here : http://mean.io/

I tried the troubleshooting as specified on the site : Updating Grunt, bower and cleaning npm and bower caches worked well. but updating npm gives an error too:
npm ERR! error rolling back Error: Refusing to delete: /usr/local/bin/npm not in /usr/local/lib/node_modules/npm
This looks like a conflict between homebrew and npm.
but anyway i have version 1.3.21 installed.
There is the same error when i am trying node server.
do you have an idea on what i can do to make the server work ?
It may be too easy, but seems like your MongoDB server is not actually running. After having installed Mongo (on your Mac, I assume?), you have to open a Terminal window/tab, run mongod and leave it running (or use screen, etc.). You can try to access MongoDB CLI by typing mongo to make sure the server is running.
#desgnl: if you don't want to run mongod command everytime you are running the grunt, you can always use third party services like MongoDB Hosting: Database-as-a-Service by MongoLab https://mongolab.com Hope this helps too!
Salam (means Hello) :)
I've developed a node.js script on my windows seven machine and it's working fine. but when I run it on my Ubuntu 12.04, the following error shows up and halts my app:
throw er; // Unhandled 'error' event
^
Error: listen EACCES
at errnoException (net.js:901:11)
at Server._listen2 (net.js:1020:19)
at listen (net.js:1061:10)

at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
and the point that caused error is .listen(80) in this line:
http.createServer(onRequest).listen(80);
^
I've also tried some other port numbers (like 100, 300, 500,...) instead of 80 and the error was still the same.
On Ubuntu you can't listen on ports < 1024 without root privileges. Try running node under sudo.
sudo node app.js
You probably have apache running on port 80, so it's conflicting.
Use another port (NOT within 0-1023), or disable apache.
Cheers
You probably have something else running on port 80, so it's conflicting.
Read here to find out what is using port 80 and stop it
http://www.cyberciti.biz/faq/find-linux-what-running-on-port-80-command/
Usually it means another server like apache is enabled. so stop it.
sudo service apache2 stop
or You have npm start already running in another terminal
or skype is running. in which case go to settings and change it's port. logout n login
Go to Tools -> Options -> Advanced -> Connections and uncheck the box "use port 80 and 443 as alternative".src
or use another port
http-server -a localhost -p 8000
I suggest to install the latest node packets, maybe directly from Node.js server, maybe compiling it.
Try to set a port which is not reserved to any service, like 3700.
Could be heplful to see some other fragment of code, though.
This can also be caused if you have something else already listening on that port - you can try changing the port from the typical default 80 to something more like 10014 and see if that helps!
I was able to rectify the error by explicitely mentionining the "IP address" along with the port when listening to the server.
