Python 烧瓶未从静态加载索引

在推特上向我推荐了Flask之后，我才开始使用Python2.7和virtualenv。它目前在“Hello World！”中运行良好，但我无法让它服务于静态文件。目前我在start.py中有以下内容：

start.py位于项目根目录中，而index.html文件位于项目根目录的/static子目录中。但是，当我运行服务器进程并浏览到127.0.0.1时，我发现此堆栈跟踪出现500错误：

我尝试将

index.html

更改为

/static/index.html

，但这仍然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。

由于将模板放置在错误的目录中，因此出现错误。看一看。模板和静态文件是两种不同的东西。模板通常位于

Templates

子目录中（可通过在中设置参数进行更改）。

Ah是。我只是注意到我在指南中忽略了这一点。
