Así que estaba creando un bot, un bot de Reddit, que vivirá en Heroku, pero a partir de la implementación, surgen problemas. La compilación se desarrolló sin problemas, hasta que iba a ver la aplicación y aparece el error de aplicación. Resulta que obtuve OSError: [Errno 98] Address already in use , pero todo funcionaba sin problemas en mi shell de Python. Aquí está mi código + estructura:

aplicación.py:

 import praw import Levenshtein import os from bs4 import BeautifulSoup as bs import requests def g(url): r = requests.get(url) if r.status_code == 404: raise Exception page = r.text soup=bs(page,'html.parser') soup = soup.find('ul',{'class':'music_list clearfix'}) soup = soup.find_all('li') return [[i.find('a')['href'],i.find('p').contents[0],i.find('h3').contents[0]] for i in soup] def k(): h = 1 l = [] while 1: try: l+=g('https://hololive.hololivepro.com/en/music?paged=%d' % h) h+=1 except: break return l from flask import Flask from threading import Thread app = Flask('') @app.route('/') def home(): return "Server Alive!" def run(): app.run(host='localhost',port=8080) def keep_alive(): t = Thread(target=run) t.start() reddit = praw.Reddit( client_id="******", client_secret="*******", user_agent="web:mv_bot:v0.1 (by u/khang1411)", username="khang1411_bot", password='*******', ) def comp(w1,w2): w2 = w2.lower() w1 = w1.lower() if w1 in w2: return 1 w2 = ''.join(ch for ch in w2 if ch.isalnum() or ch == ' ') w1 = ''.join(ch for ch in w1 if ch.isalnum() or ch == ' ') l = 0 for i in w2.split(): j = Levenshtein.ratio(w1,i) if j>l: l=j j = Levenshtein.ratio(w1,w2) if j > l: l = j return l def form(l,mode,other): if mode == 'author': return ('These are the songs that matched the author %s: \n\n' % other) + '\n\n'.join(l) + '\n\n' + '^(This comment is made by a bot, if you have improvements/complaints please contact u/khang1411)' elif mode == 'title': return ('These are the songs that matched the title %s: \n\n' % other) + '\n\n'.join(l) + '\n\n' + '^(This comment is made by a bot, if you have improvements/complaints please contact u/khang1411)' def fromauthor(author): w = ['%s by %s at link %s' % (l[2],l[1],l[0]) for l in k() if comp(author,l[1]) > 0.85] return w def fromtitle(title): w= ['%s by %s at link %s' % (l[2],l[1],l[0]) for l in k() if comp(title,l[2]) > 0.85] return w if __name__ == '__main__': keep_alive() subreddit = reddit.subreddit("test") for comment in subreddit.stream.comments(skip_existing=True): print(comment.body) if '!mv' in comment.body: try: if comment.body.split()[1] == 'author': comment.reply(form(fromauthor(' '.join(comment.body.split()[2:])),'author',' '.join(comment.body.split()[2:]))) #comment.reply() elif comment.body.split()[1]=='title': comment.reply(form(fromtitle(' '.join(comment.body.split()[2:])),'title',' '.join(comment.body.split()[2:]))) except: pass

Ejecutarlo en Repl.it y Python Shell funciona, pero no en Heroku.

P/D: implementé la aplicación Heroku a través de GitHub, esta es la imagen:

Intenté cambiar el host y el puerto, pero no funcionó. ¿Cómo puedo arreglar esto? Gracias,
