the error message has prompted / Users/helloimyhe/Documents/happylearn-admin-html/trunk/happylearn-admin-html/node\ _ modules/.bin/vue-cli-service: Permission denied does not have permission;
needs to execute the command:

chmod 777 /Users/helloimyhe/Documents/happylearn-admin-html/trunk/happylearn-admin-html/node\_modules/.bin/vue-cli-service

then re-execute

npm run serve

I also encountered the same problem. On the Internet, I saw other great gods solve this problem. The solution is to create a new vue.config.js file in the root directory with
`module.exports = {

.
devServer: {
    clientLogLevel: 'info'
}

}; `
