var gulp = require('gulp');  
var wrench = require('wrench');  


wrench.readdirSyncRecursive('./gulp').filter(function (file)  
{
    return (/\.(js|coffee)$/i).test(file);  
}).map(function (file)  
{
    require('./gulp/' + file);  
});  


gulp.task('default', ['clean'], function ()  
{  
    gulp.start('build');  
});

Installed all the dependencies and everything but still I'm getting this error.

Answer 1

Install it locally again. Run npm install --save-dev wrench. Sometimes deleting the node_modules folder and running npm install fixes these kinds of error.
