当我尝试在Express.js中启动服务器时,我收到以下错误:

[nodemon] 2.0.12

[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,json

      ^

我尝试更改端口,但它不工作。我正在使用“express”:“^4.17.1”和“nodemon”:“^2.0.12”作为版本。

有些情况下,端口上没有运行任何东西,但某些应用程序甚至您的代码无法运行。
1.以管理员身份打开PowerShell。
1.停止winnat与:第一个月
1.重新启动winnat:net start winnat

如果要从环境变量阅读端口,请先将其转换为数字:

const httpsPort = Number(process.env.HTTPSPORT) || 3443;
