我在flask中有以下代码app.py

从烧瓶导入烧瓶,呈现模板,请求
从flask_引导导入引导
app=烧瓶(名称)
引导(应用程序)
@应用程序路径(“/”)
def home():
返回渲染模板(“home.html”)
如果uuuu name uuuuuu='\uuuuuuu main\uuuuuuu':
app.run()
Where home.html:

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <title>Cheppers DevOps Challeng | Home</title>
  </head>
  <body>
    {% extends "template.html" %}
    {% block content %}
    {% endblock %}
  </body>
</html>

我试图卸载并安装Flask引导程序,但仍然没有任何结果。

我发现它出了什么问题


很明显,我导入的烧瓶引导程序库是错误的,pycharm无法识别。我发现在1.1.0版上运行的引导烧瓶

看起来像是在html文件的某个地方调用的“引导”。也许在template.html中?
