ActiveRecord::StatementInvalid (Could not find table 'spree_pages')

[cgcmart]

spree store homepage not given, that is, Rails is unable to handle requests for this static content by serving it from the public directory. It's a kind of "500" error caused by spree_static_content.
In my gemfile:
gem 'spree_static_content', github: 'spree-contrib/spree_static_content'
bundled and db migrated
gem installed show:
/usr/local/rvm/gems/ruby-2.3.0/bundler/gems/spree_static_content-41ea4c079bf9. I do not know if it's the same as this repository.
here is error log:
