python flask 进程问题

运行：

from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
    return 'Hello World!'

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

报错：

 * Serving Flask app "t" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
Traceback (most recent call last):

OSError: [Errno 98] Address already in use

解决方案：

$ ps -fA | grep python
henry 127112 1181 0 12:07 ? 00:00:05 /usr/bin/python /usr/bin/x-terminal-emulator
henry 127201 124727 0 12:09 ? 00:00:01 python3 -u /home/henry/dev/myproject/flaskr/flaskr.py
henry 127252 127122 0 12:20 pts/4 00:00:00 grep --color=auto python
$ kill 127201
————————————————

注意：关键问题：杀死占用的进程
查看： ps -fA | grep python
杀死：kill 号
