PermissionError: [Errno 13] Permission denied: '/tmp/ngrok/ngrok'

This is my code

from flask import Flask
from flask_ngrok import run_with_ngrok

app = Flask(__name__)
run_with_ngrok(app)

@app.route("/")
def hello():
    return "Hello Geeks!! from Google Colab"

app.run()

When I run it, I get the following error:

 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.

I installed flask-ngrok in PyCharm. I even changed read and write permissions (chmod -R 755 /tmp/ngrok/ngrok) but I still get the same error as above.

I'm also having this, but since I'm in a macOS, I got PermissionError: [Errno 13] Permission denied: '/var/folders/hh/vz60ml8n45q2bw6b4_zltsqc0000gn/T/ngrok/ngrok. I tried downgrading flask-ngrok to 0.0.23 and flask to 0.12.2, but the same error appears.

I am facing the same issue but I can't used sudo :( is there any chance of having another solution?

I fixed it replacing the line #30 (flask_ngrok.py) from: os.chmod(executable, 777) to: os.chmod(executable, stat.S_IEXEC) # Make file for the current user executable.

importing lib stat from python core...

My OS specifications:

LSB Version: core-11.1.0ubuntu2-noarch:printing-11.1.0ubuntu2-noarch:security-11.1.0ubuntu2-noarch Distributor ID: Linuxmint Description: Linux Mint 20.1 Release: 20.1 Codename: ulyssa

I dno1t know if its ok for other OS...

I have the same issue on Mac and VS Code. Did anyone find a solution for Mac?

This solution fixed it for me.
