我刚开始在推特上向我推荐使用带有Python 2.7和virtualenv的Flask。它目前适用于“Hello World!"但是我不能让它来提供静态文件。目前我在 start.py :
中有这个from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def home():
author = "Old Mother Hubbard"
name = "Arthur Dent"
return render_template('index.html', author=author, name=name)
if __name__ == "__main__":
app.run()
start.py 位于项目根目录中,我在项目的 / static 子目录中有 index.html 文件根。但是,当我运行服务器进程并浏览到127.0.0.1时,我的堆栈跟踪出现了500错误:

TemplateNotFound: index.html

我尝试将index.html
更改为./static/index.html
,但这仍会导致基本相同的错误。当模板位于文件夹中时,为什么会出现TemplateNotFound
错误?
我正在使用项目根目录中的python start.py
启动服务器进程。
答案 0 :(得分:1)
您收到错误是因为您将模板放在了错误的目录中。看看quickstart。模板和静态文件是两回事。模板通常位于templates
子目录中(可以通过在App constructor中设置参数来更改。)
