from flask import Flask
app = Flask(__name__)
@app.route('/')def hello_world():
return 'Hello World!'
if __name__ == '__main__':
app.run()
照着网上教程写了一个hello world，删除了那个文件后再写就老是报错
Traceback (most recent call last):
File "hi.py", line 10, in <module>
app.run(host='0.0.0.0')
File "/usr/lib/python3/dist-packages/flask/app.py", line 841, in run
run_simple(host, port, self, **options)
File "/usr/lib/python3/dist-packages/werkzeug/serving.py", line 691, in run_simple
s.bind((hostname, port))
OSError: [Errno 98] Address already in use
