// Configure the default development mode for packaging
// Configure the entry path: the file to be packaged
// Configure exit path: specify packaged files
/* output: path. join (_dirname,'. / dist'), // specify the path of the output*/
Path: path. join (_dirname,'. / dist/css'), // specify the path of the output
filename:'main.css', // specifies the name of the output file
