Question

我查看了这个问题，发现每个人都和另一个相似：

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：

jinja2.exceptions.TemplateNotFound: home.html

Answer 1

函数render_template()在名为templates的文件夹中查找html模板。确保您的项目有此文件夹，并且所有html文件都放在其中。可以在here中找到有关典型Flask项目结构的更多详细信息。

jinja2.exceptions.TemplateNotFound：home.html
