问题描述

我正在使用python 3运行MacOSX.该文件夹和文件有755，但我也曾在777中进行过运气测试.我的问题是，如果我拥有正确的权限，为什么它不让我在没有sudo的情况下运行.还是我的设置不正确?

I am running MacOS X with python 3. The folder and files have 755 but I have also tested it in 777 with no luck. My question is if I have the right permissions why does it not let me run without sudo. Or are my settings incorrect?

cris-mbp:ProjectFolder cris$ python3 zbo.py

您正在尝试在

You're trying to run the app on a privileged port (81) - if you use a higher port such as 5000 you won't need sudo privileges.
