Logging prevents Flask application from starting

I am using the hello world version of Flask. I would like to add logging to a file. When I add the following line, the Flask app never starts:



logging.basicConfig(filename=os.path.join(os.path.dirname(os.path.realpath(__file__)), 'errors.txt'),
level=logging.ERROR)


Full code:



import logging
import os

from flask import Flask

app = Flask(__name__)


@app.route('/')
def hello_world():
return 'Hello, World!'


logging.basicConfig(filename=os.path.join(os.path.dirname(os.path.realpath(__file__)), 'errors.txt'),
level=logging.ERROR)

app.run()
