Javascript错误Object函数没有方法'url'

我曾考虑将syte用作博客。我已经设置好了，但当我尝试使用侧面导航按钮时，我会收到以下javascript错误：

Object function (a,b){return new e.fn.init(a,b,h)} has no method 'url' [http://127.0.0.1:8000/static/js/components/links.js:15]

这里是links.js:

var $url;
function setupLinks() {
  $('a').click(function(e) {
      if (e.which == 2)
          return;
      e.preventDefault();
      e.stopPropagation();
      if (this.href == $url)
          return;
      var url = $.url(this.href.replace('/#!', ''));
      $url = this.href;
      if (this.id == 'home-link' && window.location.pathname == '/') {
         $('#github-profile').remove();
         $('#dribbble-profile').remove();
         $('#twitter-profile').remove();
         $('#instagram-profile').remove();
         $('#lastfm-profile').remove();
         $('.modal-backdrop').remove();
         adjustSelection('home-link');
      }
      else if(this.id == 'instagram-link' && instagram_integration_enabled) {
         $('#github-profile').remove();
         $('#dribbble-profile').remove();
         $('#twitter-profile').remove();
         $('#lastfm-profile').remove();
         $('.modal-backdrop').remove();
         adjustSelection('instagram-link');
         setupInstagram(this);
      }
      else if (twitter_integration_enabled && (url.attr('host') == 'twitter.com' || url.attr('host') == 'www.twitter.com')) {
         $('#github-profile').remove();
         $('#dribbble-profile').remove();
         $('#instagram-profile').remove();
         $('#lastfm-profile').remove();
         $('.modal-backdrop').remove();
         adjustSelection('twitter-link');
         setupTwitter(url, this);
      }
      else if (github_integration_enabled && (url.attr('host') == 'github.com' || url.attr('host') == 'www.github.com')) {
        $('#twitter-profile').remove();
        $('#dribbble-profile').remove();
        $('#instagram-profile').remove();
        $('#lastfm-profile').remove();
        $('.modal-backdrop').remove();
        adjustSelection('github-link');
        setupGithub(url, this);
      }
      else if (dribbble_integration_enabled && (url.attr('host') == 'dribbble.com' || url.attr('host') == 'www.dribbble.com')) {
         $('#twitter-profile').remove();
         $('#github-profile').remove();
         $('#instagram-profile').remove();
         $('#lastfm-profile').remove();
         $('.modal-backdrop').remove();
         adjustSelection('dribbble-link');
         setupDribbble(url, this);
      }
      else if (lastfm_integration_enabled && (url.attr('host') == 'lastfm.com' || url.attr('host') == 'www.lastfm.com')) {
        $('#twitter-profile').remove();
        $('#github-profile').remove();
        $('#dribbble-profile').remove();
        $('#instagram-profile').remove();
        $('.modal-backdrop').remove();
        adjustSelection('lastfm-link');
        setupLastfm(url, this);
      }
      else {
         window.location = this.href;
      }
  });
}
function adjustSelection(el) {
  $('.main-nav').children('li').removeClass('sel');
  $('#' + el).parent().addClass('sel');
  if (el == 'home-link')
    $url = null;
}

这似乎是缺少javascript库的问题。Syte安装说明要求您在部署站点之前运行compress.py。它应该自动导入和压缩javascript库，但它似乎并没有这么做。这是压缩.py:

import os
import sys
import subprocess
import shlex
import traceback
path_to_here = os.path.abspath(os.path.dirname(__file__))
path_before_site = path_to_here[0:path_to_here.rfind('syte')]
sys.path.append(path_before_site)
os.environ['DJANGO_SETTINGS_MODULE'] = 'syte.settings'
from django.conf import settings
def compress_statics():
    try:
        #This won't work on windows.
        subprocess.check_call(shlex.split('mkdir -p static/css static/js/min'))
    except Exception:
        print 'Make sure to create "syte > static > css" and "syte > static > js > min" before compressing statics.'

我的javascript技能缺乏，所以任何帮助都将不胜感激！
