在bash上运行Flask:无法导入"app" [英] Running Flask on bash: Could not import "app"

问题描述

我在Flask上编写了此代码:

I made this code on Flask:

from flask import Flask

app = Flask(__name__)

@app.route('/')
def index():
    return "hi"

即使如此，我还是尝试使用 flask run 运行它，它显示以下消息:

Even so, fi I try to run it with flask run it shows this message:

* Serving Flask app "app.py"
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
Usage: flask run [OPTIONS]

Error: Could not import "app".

我在做什么错了?

应用程序结构:

website/
  | - app.py

推荐答案

from flask import Flask

app = Flask(__name__)

@app.route('/')
def index():
    return "hi"


if __name__ == '__main__':
  app.run(host='0.0.0.0', port=30006, debug=True)

在放置此代码的同一目录中运行.

Run in the same directory where this code is placed.

python3 file_name.py

您可以在

http://0.0.0.0:30006/
