Python 防止烧瓶app'；从不需要的重新加载中删除开发服务器

我用命令

pymain.py

在运行一个flask应用程序。在我的文件中，最后一行是app.run（debug=True，port=7000）。我已经声明了

app=Flask（\uuuuu name\uuuuuu）

。我需要服务器每次重新启动。但是服务器会重新加载不需要的文件，甚至不允许我查看页面！日志是：

但是，我正在使用dir:

F:\flask app\app-1\main.py

上的文件，在我的VS代码中打开文件夹

F:\flask app\app-1

。我只想在更改文件夹中的文件时重新加载烧瓶：

F:\flask app\app-1

，而不是任何其他文件！有办法吗？一些规格：

C:\User\new>python -V
Python 3.9.1

C:\User\new>python -m flask --version
Python 3.9.1
Flask 1.1.2
Werkzeug 1.0.1

C:\User\new>cmd
Microsoft Windows [Version 10.0.19042.985]

我使用的是Windows 32位。

这有点奇怪，但我认为可能是因为您使用的是全局python解释器。我建议创建一个虚拟环境，如

python-m venv env

然后

\env\Scripts\activate

---

然后在那里安装所有软件包并再次尝试运行flask。

我没想到VENV会帮我！谢谢，这对我来说很有效。这对我来说甚至有些出乎意料。我不使用windows，但我认为可能是这样。不管怎样，很高兴它成功了。
