ERROR finding /Users/mspro/www/studies/polymer/testb/dist/bower_components/paper-behaviors/paper-inky-focus-behavior.html

the paper-behaviors folder was empty (except for the README.md) i then copied the content of the bower_components/paper-behaviors folder of the psk-light download and the error was gone, but starting the demo with gulp resulted in an empty page

looking at the console in chrome i get following errors:

Uncaught TypeError: Polymer.IronMeta is not a function /deep/ combinator is deprecated. See https://www.chromestatus.com/features/6750456638341120 for more details. iron-icon.html:168 Uncaught TypeError: this._meta.byKey is not a function page.js:797 Uncaught TypeError: Cannot read property 'length' of undefined

here's where i give up for now,

my node version is v4.2.4 on mac osx 10.10.5 Chrome 47.0.2526.106 (64-bit)

does anyone have a idea how to solve this problem?

thanks

I tried again today on another computer with a fresh download of the same PSK and this time i managed to get it working, still don't know what went wrong, the main difference is the os (the computer with the working version has mac os 10.11.2), node and npm versions are the same. - Marco St

It would be helpful to include the actual commands you ran and which version of the PSK you tried. Here are the steps I followed and was able to get the PSK installed and run gulp and gulp serve without error.

  • Download Polymer Starter Kit

  • Under Intermediate - Advanced Users click on polymer-starter-kit-1.2.1.zip

  • Extract ZIP file to preferred location

  • Install Node.js if needed before running the next step

  • With Node.js installed, run the following one liner from the root of your Polymer Starter Kit download: npm install -g gulp bower && npm install && bower install OR if admin permission is needed: sudo npm install -g gulp bower && npm install && bower install NOTE: This step takes a few minutes to install all of the dependencies.

  • Then start the web server using this one liner from the root of your Polymer Starter Kit download: gulp serve
