Issue
I am learning angular 2 and for the first time I am using the angular CLI project to create a sandbox project.
I was able to run the command "ng serve" and it works great. I wanted to stop it from running so I ran "Control Z".
When I tried to run the "ng-serve" command again it gives me "Port 4200 is already in use."
I ran "PS" to get a list of the PID and killed the PID for the angular-cli and ran "ng-serve" again still it gives the same port in use error.
Solution
This is what I used to kill the progress on port 4200
For linux users:
sudo kill $(sudo lsof -t -i:4200)
You could also try this:
sudo kill `sudo lsof -t -i:4200`
For windows users:
Port number 4200 is already in use. Open the cmd as administrator. Type below command in cmd:
netstat -a -n -o
And then, find port with port number 4200 by right click on terminal and click find, enter 4200 in "find what" and click "find next": Let say you found that port number 4200 is used by pid 18932. Type below command in cmd:
taskkill -f /pid 18932
For UNIX:
alias ngf='kill -9 $(lsof -t -i:4200);ng serve'
Now run ngf (instead of ng serve) in terminal from the project folder. This will kill all processes using the port 4200 and runs your Angular project.
