下記のソースコードとbashの結果を記載した方がいいと思います。
また、読みにくいので、他の部分についても言えることですが、コードのマークダウンを利用してください。
・user.rb
・routes.rb
・$rails db:migrate:status

The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

===============================================================================

Depending on your application's configuration some manual setup may be required:

1. Ensure you have defined default url options in your environments files. Here
is an example of default_url_options appropriate for a development environment
in config/environments/development.rb:

config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }

In production, :host should be set to the actual host of your application.

* Required for all applications. *

2. Ensure you have defined root_url to *something* in your config/routes.rb.
For example:

root to: "home#index"

* Not required for API-only Applications *

3. Ensure you have flash messages in app/views/layouts/application.html.erb.
For example:

<p class="notice"><%= notice %></p>
<p class="alert"><%= alert %></p>

* Not required for API-only Applications *

4. You can copy Devise views (for customization) to your app by running:

rails g devise:views

* Not required *
