OSError: [Errno 98] Address already in use Flask error
I am working on a small flask project.
I have been working within a virtual environment with python 2.7. So I migrated to version 3.7.
Every time I start the server, I run into this error,
OSError: [Errno 98] Address already in use
Here is the solution.
Enter the following commands in the terminal
| ps -fA | grep python
This will select and display all the processes with python matching pattern
Check the one with “flask” in the path and note down its PID(process ID). This should be the second column of the output.
Then enter this command
| kill -9 pid
Replace pid with the PID from the previous command
Then Restart your server
| flask run
And it works!!
