How to view the Polymerfire demo using Polymer’s `polymer serve` polyserve server?

问题

I want to view this demo of Polymerfire in my browser.

I expect to see the demo run in my browser. Instead, I see a blank page and the following console error.

console.log.error.message

GET http://localhost:8080/ 404 (Not Found)
Navigated to http://localhost:8080/

I used the following procedure:

1. I installed the Polymer-CLI multi-tool per the instructions found here.
2. I created a project using the Polymer Starter Kit (PSK).
3. I named the project my-app.
4. I installed the Github repo found here using the CLI:
   bower install ---save firebase/polymerfire
5. I opened the terminal and navigated to the app's root directory.
   cd path/to/my-app
6. I ran the following Polymer-CLI command (per the instructions found here).
   polymer serve

What can I do to try and solve this so I can see the demo run in my browser?

回答1:

The best way to run an elements demo is to check it out...

git clone https://github.com/firebase/polymerfire.git

cd polymerfire

bower install

polymer serve

I have never tried to run the demos from a bower install'd folder but, the above method will work.

You also have to navigate to the correct localhost path:
http://localhost:8080/components/polymerfire/demo/

So the complete procedure (from the command line) is:

First, install the polymer-cli per the instructions found here.

npm install -g bower
npm install -g polymer-cli

Then run the following.

shell.sh

git clone https://github.com/firebase/polymerfire.git
cd polymerfire
bower install
polymer serve
open http://localhost:8080/components/polymerfire/demo/
