Let\u00b4s say we have this warning “Port 4200 is already in use” when running the ng serve command<\/strong><\/em>“.<\/p>\n\n\n\n

And all the (IDE) terminal are closed.<\/p>\n\n\n\n

This is what I used to kill the progress on port 4200 :<\/p>\n\n\n\n

For linux users:<\/strong><\/p>\n\n\n\n

sudo kill $(sudo lsof -t -i:4200)<\/code><\/pre>\n\n\n\n
You could also try this:<\/p>\n\n\n\n
sudo kill `sudo lsof -t -i:4200`<\/code><\/pre>\n\n\n\n
<\/div>\n\n\n\n
For windows users:<\/strong><\/p>\n\n\n\n
Port number 4200 is already in use. Open the cmd as administrator. Type below command in cmd:<\/p>\n\n\n\n
netstat -a -n -o<\/code><\/pre>\n\n\n\n
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:<\/p>\n\n\n\n
taskkill -f \/pid 18932<\/code><\/pre>\n\n\n\n
Windows User ( Alternative 2<\/strong>)<\/p>\n\n\n\n
Open your cmd.exe<\/code> as administrator<\/code>,<\/p>\n\n\n\n
then Find the PID<\/code> of port 4200<\/code><\/p>\n\n\n\n
netstat -ano | findstr :4200<\/code><\/pre>\n\n\n\n
\nhttps:\/\/i.stack.imgur.com\/mOSAv.png\n<\/div><\/figure>\n\n\n\n
Here I have 3 PID :<\/p>\n\n\n\n
  • Red one is from “ng-serve” (127.0.0.1:4200) that LISTENING<\/code><\/li>
  • Green one is from “your browser”<\/li><\/ul>\n\n\n\n
    kill only port 4200 (kill the red PID):<\/p>\n\n\n\n
    taskkill \/PID 15940 \/F<\/code><\/pre>\n\n\n\n
    \nhttps:\/\/i.stack.imgur.com\/ATfte.png\n<\/div><\/figure>\n\n\n\n
    note : kill the green one will only lead your browser closed by force.<\/em><\/p>\n\n\n\n
    now you can do “ng-serve” to start your angular app at the same port 4200<\/p>\n\n\n\n
    <\/div>\n\n\n\n
    For UNIX:<\/strong><\/p>\n\n\n\n
    alias ngf='kill -9  $(lsof -t -i:4200);ng serve'<\/code><\/pre>\n\n\n\n
    Now run ngf<\/strong> (instead of ng serve<\/em>) in terminal from the project folder. This will kill all processes using the port 4200 and runs your Angular project.<\/p>\n","protected":false},"excerpt":{"rendered":"
