“Uncaught Reference Error: Polymer is not defined”

问题:

so I didn't touch my current project for almost one month and after that, nothing is running anymore and I get the message

Uncaught Reference Error: Polymer is not defined

for each of my Polymer-Elements and this one once:

 Failed to load resource: the server responded with a status of 404 (Not Found)     http://localhost:9000/bower_components/tools/loader/loader.js
 Uncaught ReferenceError: PolymerLoader is not defined

I have Polymer included in my main html-file like this:
<script src="bower_components/polymer/polymer.js"></script>

I already deleted and reinstalled all my bower_components, downloaded Polymer directly from GitHub and added the PolymerLoader manually to the referenced directory(deleted it again after it did not work). I am unsing Version 0.0.20131010 of Polymer (I know it's very old, but it used to work before...) and the newest version of Bower. I can't find an explanation for all this.

The only thing that has changed is the IP-address of the computer, which I am not refering to anywhere in my code.

I hope you could share some of your thoughts on this with me.

Something is wrong / misconfigured with the HTTP server that's serving these files out. It's not a polymer error if you're getting a 404 for the .js files.

Please ask a new question and include information about the tools that you're using to serve out HTTP.
