python - jinja2.exceptions.TemplateNotFound: home.html

问题描述

我查看了这个问题，发现每个人都遇到了类似的问题：

from flask import Flask,render_template
app = Flask(__name__)



@app.route("/")
@app.route('/home')
def home():
   return render_template('home.html')


@app.route('/about')
def about():
    return render_template('about.html')

if __name__ == '__main__':
    app.run(debug=True)

错误：

解决方案

请注意目录名称。它应该是“模板”而不是“模板”。我犯了同样的错误，现在解决了
