Windows环境运行Django项目报错：无端口访问权限

问题场景 #

在Windows系统运行Django项目时，执行python manage.py runserver或python manage.py runserver "IP":"PORT"命令，均返回错误：Error: You don't have permission to access that port，搜索到的现有方案多针对Linux系统。

解决方案 #

1. 切换到非特权端口 #

Windows系统中1-1023为特权端口，普通用户无权限直接使用，换成1024及以上的端口即可，示例命令：

python manage.py runserver 8001

指定IP和端口的写法：

python manage.py runserver 0.0.0.0:8001

2. 以管理员身份运行终端 #

右键点击命令提示符、PowerShell或其他终端工具，选择「以管理员身份运行」，再执行启动命令，即可获取权限使用80、443这类特权端口。

3. 检查端口占用情况 #

用以下命令查询目标端口是否被其他进程占用：

netstat -ano | findstr :<你的端口号>

若端口被占用，执行以下命令结束对应进程（替换<进程ID>为查询到的PID）：

taskkill /F /PID <进程ID>

4. 排查防火墙拦截 #

Windows防火墙可能阻止Django访问端口，可临时关闭防火墙测试，或在防火墙设置中添加允许Django程序通过的入站规则。

项目配置文件参考 #
