// If your port is set to 80,
// use administrator privileges to execute the command line.
// For example, Mac: sudo npm run
// You can change the port by the following method:
// port = 9527 npm run dev OR npm run dev --port = 9527
// 如果端口设置为80，
// 使用管理员权限执行命令行。
// 例如，Mac:sudo npm run
// 可以通过以下方法更改端口：
// port = 9527 npm run dev OR npm run dev --port = 9527
const port = process.env.port || process.env.npm_config_port || 9527 // dev port
// All configuration item explanations can be find in https://cli.vuejs.org/config/
