Webapp dont work

[Diee92]

hello, first thanks for the program, I have a problem with the webapp, I installed it in windows, everything is working but when I want to start the page it shows me this error

Traceback (most recent call last):
File "/usr/local/bin/nxbt", line 33, in
sys.exit(load_entry_point('nxbt', 'console_scripts', 'nxbt')())
File "/vagrant/nxbt/cli.py", line 321, in main
from .web import start_web_app
File "/vagrant/nxbt/web/init.py", line 1, in
from .app import start_web_app
File "/vagrant/nxbt/web/app.py", line 9, in
from flask import Flask, render_template, request
File "/usr/local/lib/python3.8/dist-packages/flask/init.py", line 19, in
from . import json
File "/usr/local/lib/python3.8/dist-packages/flask/json/init.py", line 15, in
from itsdangerous import json as _json
ImportError: cannot import name 'json' from 'itsdangerous' (/usr/local/lib/python3.8/dist-packages/itsdangerous/init.py)

any ideas? Thank you

The only workaround for nxbt to work is by downgrading Flash to version 1.0.3 then remove the "from itsdangerous" from line 15 in the file "/usr/local/lib/python3.8/dist-packages/flask/json/init.py", that's it.

it worked! Thanks a lot

any ideas?

I'd like to try updating the dependencies. from what I see they are about a year old and some libs had major upgrades which introduce breaking changes. also, from what ive seen some code (i think dependency code) would not run with python3.8 or later.

for the specific error you encountered you can try downgrading jinja2. but i fear that'll let you spiral down the dependency mess i encountered :D (no critique, just saw what i stated above)

Ok, i'll try to find the........ (looking at l4desu-mizu's post before i could say "workarounds.")

Well, i was too late then, better luck next time for me...... ¯\_(ツ)_/¯

same error here, any ideas?

although I should try updating the dependencies yet again, you could try the branch that I've linked (not tested for a while)

I tried doing all of this today and am still getting the "ImportError: cannot import name 'escape' from 'jinja2' (/usr/local/lib/python3.8/dist-packages/jinja2/init.py)" when trying to launch the webapp

I found this fork from useful-forks and luckily it works. Just create a venv, activate it, and run below to install it.

pip install git+https://github.com/piratasdoraio/nxbt.git
