Gulp + Browserify error

Hi, when I try to import vue-mdl module I get this error:

Cannot find module '!!./../node_modules/css-loader/index.js?sourceMap!./../node_modules/vue-loader/lib/style-rewriter.js!./../node_modules/vue-loader/lib/selector.js?type=style&index=0!./select.vue' 

My gulpfile.js

var gulp = require('gulp'),
    browserify = require('browserify'),
    source = require('vinyl-source-stream'),
    buffer = require('vinyl-buffer'),
    uglify = require('gulp-uglify'),
    sass = require('gulp-sass'),
    livereload = require('gulp-livereload'),
    concat = require('gulp-concat'),
    babel = require('gulp-babel');

gulp.task('browserify', function() {
    browserify('src/app.js')
        .transform('babelify', {presets: ['es2015', 'react']})
        // .transform('envify')
        .transform('vueify')
        .bundle()
        .on('error', function(e) {
            console.error(e.message);
        })
        .pipe(source('app.js'))
        .pipe(buffer())
        .pipe(gulp.dest('www/js'))
        .pipe(livereload())
});

Thanks. I used import VueMdl from 'vue-mdl/dist/vue-mdl.min'; and now everything works perfectly!
