I use flask inside a virtualenv (on a Linux machine) which causes the library to fail as it won't have the permission to write to /tmp/ngrok/ngrok.

Potentially could you save it in the virtualenv?

This is the traceback.

Hi,

The permission to the ngrok download file are not correctly setup under Python 3.7. I solved this by modifiying line 29 of flask_ngrok.py with: os.chmod(executable, 777) to os.chmod(executable, 0o777) Sorry if I am not following the standard process for patching, I am not a developper.

Also a side not it would be good if flask-ngrok carry the kwargs arguments to the call of app.run.

have some error code I can't fix it Use a production WSGI server instead.

As you are replacing the current run function, you break any existing functionality that relies on passing in parameters. Maybe you can pass them through your function into the old function?

When attempting to write a simple flask websocket app with socketio, adding this package produces TypeError: new_run() got an unexpected keyword argument 'host'

Add an option to set an auto-token and the ngrok download link is being generated from the ngrok download webpage automatically Can you check it out please

A fix for #29

The platform.system()output for the Raspberry Pi OS is also 'Linux'. https://github.com/gstaff/flask-ngrok/blob/33a2e70898c4fb72b645715dacd8789769a99350/flask_ngrok.py#L50

This leads to a download of the wrong ngrok executable for ARM devices.

Added an additional if else statement in line #55 flask_ngrok.py

elif system == "Linux":
        if 'arm' in os.uname().machine and platform.architecture()[0] == '64bit':
            url="https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-arm64.zip"
        elif 'arm' in os.uname().machine and platform.architecture()[0] == '32bit':
            url="https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-arm.zip"
        else:
            url = "https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip"

Any idea why I'm getting this error with a basic test script? i'm running the script as: sudo python3 flaskngrokdemo.py

raspberry pi zero (not 64bit, maybe the problem?)

I'm trying to run flask application on colab but I keep seeing the following when I go to the tunneled page:-

Code:-

# flask_ngrok_example.py
from flask import Flask
from flask_ngrok import run_with_ngrok

app = Flask(__name__)
run_with_ngrok(app)  # Start ngrok when app is run

@app.route("/")
def hello():
    return "Hello World!"

if __name__ == '__main__':
    app.run()
