In Python3 I have a program to test the web framework bottle:
from bottle import route, run
@route('/')
def index():
return "olá pessoas"
if __name__ == '__main__':
run()
I am running the programs inside a virtualenv, in the command line. But there is this error:
(live-de-python) reinaldo@reinaldo-Inspiron-5567:~/Documentos/Code/live-de-python/repo$ python3 basic_bottle.py

OSError: [Errno 98] Address already in use
I'm using Ubuntu. Does the error say that port 8080 is already in use? But I have no other program open
Please, does anyone know what it can be?
The port 8080 is already used by an other process. You probably launched the script and forgot to end it. Check with
$ ps -aux | grep basic_bottle
Or simply change the port with run(port=8090).
