i have a problem running flask. It started fine until I loaded a simple login form.
when running flask via gitbash, I get an error like this
flask run
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.

* Debug mode: off
Usage: flask run [OPTIONS]
Try 'flask run --help' for help.

raise ImportError("The crypt module is not supported on Windows")
ImportError: The crypt module is not supported on Windows
btw, i used windows
remove this from the top of the file:
from crypt import methods
it should work again. At least it did for me. VSCode may have autogenerated this for you.
This thing occur most times with auto-import in vs code.
If you inspect your code critically, you'd notice that your vs-code editor has automatically included the line of code from crypt import methods above your imports.
Just comment or delete it out and try re-running your app again, you'd be in good shape.

I have developed the following message when running flask. I attempted to add overlapped, via pip install overlap. I can't find answers to this. This is my terminal output. Can someone please help?

Did you mean to import NULL from asyncio.windows_event? I'm guessing it was automatically imported by your IDE, None is likely what you're looking for instead of NULL, which isn't a keyword in Python.
So, I created a small flask API. Basically a wrapper for another API.
I used requests-futures to send multiple calls asynchronously.
I set up my virtual environment. Everything works exactly as I intend. However, when I try to run some tests I've written (using python -m unittest) this is the error I get:
======================================================================
ERROR: test (unittest.loader._FailedTest)

ImportError: Failed to import test module: test

I have reinstalled the module using pip. I made sure to pip freeze > requirements.txt just in case it was reading module availability from there. But all in all I'm stumped. If anyone could help me out here, I'd greatly appreciate it.
I have a strange error, that I never saw before.
I wrote a small http web server using flask and when I run I got the error bellow.
I am using virtual env and my python version is 3.8
What can be?
from flask import Flask, request
app = Flask(__name__)
#app.route("/")
def index():
print(request.get_json())
if __name__ == "__main__":
app.run(debug=True)

The issue comes from the first traceback:
ModuleNotFoundError: No module named 'http.server'; 'http' is not a package
You need to rename the http.py file to something else because it is overriding the standard library http module. To fix it, you will need to do the following:
Rename the file http.py to something else.
Remove .pyc files in the project
find . -name "*.pyc" -delete
Run the program again
Python3 uses socketserver, all lowercase. Python2 uses SocketServer
this maybe helps you
`
pip uninstall Flask
pip uninstall Werkzeug
pip install Flask
pip install Werkzeug

everyone. Can't understand where my problem is.
My structure is:
But in my cmd I have:

nt.

Thanks in advance
Maybe I should run it as
python run.py
?
I have init.py in my apps
Why, when I try to run a flask application from the console, I encounter an error: ModuleNotFoundError:
$ python run.py
Traceback (most recent call last):
File "run.py", line 1, in <module>
from src.app.controller import app

or
$ env FLASK_APP=run.py flask run

* Debug mode: off

Here is a project screenshot:
But if I run the application from Paycharm, then everything works fine.
How to solve this problem?
Just try to change the code to this:
from app.controller import app
from config import Config
The file run.py is already in the directory src. The error occurs, because there is no other folder called src in the directory where the file run.py is stored.
