polymer - error when installing polymer designer on local machine

Question

I have cloned the git for polymer designer on my mac. Following the getting started instructions for Polymer designer works fine until I run bower install

-bash: bower: command not found

Also index.html cannot be loaded by the local httpserver.

I see this is a standard error but several solutions on stack. I need to setup this tool locally to add a custom library.

Answer 1

bower をインストールする必要があります: http://bower.io/#install-bower

npm install -g bower

Answer 2

これを試してください: bower install --save Polymer/polymer
