[Vuejs]-Vue starts port 80 under mac and reports an error

This error happens when the port is already in use. You can solve this with two options.

  • Kill the port

  1. Check if the port is already in use using this command lsof -i :80
  2. Kill the port using the PID that will be provided if the port was in use using kill {{PID}}

  • Run the project on a different port

You can actually run your vue app on a different port

  1. Using Npm -> npm run serve --port 8080
  2. Using Yarn -> yarn serve --port 8080

As your machine gets started, it will need to know the mapping of some hostnames to IP addresses before DNS can be referenced. This mapping is kept in the /etc/hosts file. In the absence of a name server, any network program on your system consults this file to determine the IP address that corresponds to a host name.

127.0.0.1           localhost       
127.0.0.1           yourdomain.com

Then you can run npm run dev --host yourdomain.com with custom host/port using vue-cli.

Also you can change the devServer in vue.config.js
