Guide me how to start gulp serve and how resolve these error

Solution

  • I tried these steps. Its work for me.

    Globally install gulp.

    Next need to install the project’s local dependencies (that’s where it’s looking for browser-sync). To do that,

    cd into the project directory and run npm install.

    Then try gulp serve.

    You can also try following lines

    npm i browser-sync --save

    then

    npm start
