【问题描述】:
我在基于 vagrant 的 Linux 系统上运行此脚本,这是运行烧瓶应用程序的简单基本代码,我收到此错误:
提高 child_exception_type(errno_num, err_msg)
PermissionError: [Errno 13] 权限被拒绝
这是脚本:
#!/usr/bin python3
from flask import Flask
app = Flask(__name__)
@app.route('/')
@app.route('/hello')
def helloworld():
return 'Hello and Welcome to flask'
if __name__ == '__main__':
app.debug = True
app.run(host='0.0.0.0', port=5000)
我得到的错误:
vagrant@vagrant:/vagrant$ python3 project.py
