筆者的環境：
OS: Ubuntu Linux
Browser: Chrome, Firefox
每次希望啟動chrome瀏覽器，系統都會報錯：
1 browser-sync start -s --directory -f **/* --browser chrome
Couldn't open browser (if you are using BrowserSync in a headless environment, you might want to set the open option to false)
正確的啟動方式應為：
browser-sync start -s --directory -f **/* --browser google-chrome
