Steps to reproduce:
- I followed this tutorial https://code.visualstudio.com/docs/python/tutorial-flask step by step but i used virtualenv instead of env because my project is written in python 2.7

I've no output because i can't debug
I don't know if this is a bug but i couldn't find any info about this error anywhere. I could debug flask with vscode in os x without problems, but in windows i receive this error. I repeat the tutorial multiple times but the result is always the same. The tutorial is written by python 3 but i changed the "env" to "virtualenv", i don't know if i should make any other change.
i think the problem is with python extension but i didn't be able to find any config file to modify this command:
C:\Users\s3rgy0\envs\venv\Scripts\python.exe c:\Users\s3rgy0.vscode\extensions\ms-python.python-2020.2.64397\pythonFiles\ptvsd_launcher.py --default --client --host localhost --port 51765 -m flask run --no-debugger --no-reload --host=192.168.0.163 --port=3002
If i could remove this options: "--default --client --host localhost --port 51765" it should work, but i don't know how.
Please help.
Thanks.
@enigmadevs can you check if you have ptvsd
installed in C:\Users\s3rgy0\envs\venv\Scripts\python.exe
environment? if so can you uninstall it.
No, ptvsd is not in this path.
I have the same problem. I found out that the command would work work fine in python 3.8 environment. The problem is that my project is not compatible with python 3.8 and therefore i have to use python 2.7.
@int19h thanks for your feedback. Now i'm getting another error
