Я запустил новый проект на платформе AWS C9
, и у меня возникла проблема с отображением веб-страницы с помощью фреймворка Flask
Фреймворк работает правильно, он может возвращать сообщения (по умолчанию), но когда я пытаюсь вернуть шаблон (HTML-страницу), я получаю сообщение об ошибке: "TemplateNotFound"
Я оставлю код ниже и сообщения об ошибках
import os
from flask import Flask, render_template, request
app = Flask(__name__)
@app.route("/")
@app.route("/home")
def home():
return render_template('templates/home.html')
@app.route("/about")
def about():
return "<h1>Flask is working</h1>"
if __name__=="__main__":
app.run(host='0.0.0.0', port=8080)
app.debug = True
Трассировка стека: -
