I am new to rails platform. I am developing a simple applicatoin in which I wa开发者_JS百科nt to import all my gmail contacts. I Came to know that I can use cardmagic gem for importing contacts. It is given on link below.

https://github.com/cardmagic/contacts.git

I want to know how to integrate it in my application.I am trying to install it using

 gem install contact

Then I did

bundle install 

&

bundle update

Both commands executed without error still am not getting whether the gem is installed or not.I checked gemfile to check its entry.It is not there. Please guide me whether I am going right or not & also tell me how can I use its functionality. Please also tell me about good resources that will elaborate more about gems & their uses. Thank you

If you're using Bundler, you need to add the gem to your Gemfile, and not install it with gem install contact.

If you look at the RubyGems page for contacts you can see how they recommend adding it:

gem "contacts", "~> 1.2.4"

Once it's in your Gemfile, just run bundle from within your application directory and it will install it.
