I am installing one app and I was in this step that I should run bundle install and I get this error 

enter code here➜  mavatar git:(master) ✗ bundle install

 Your Gemfile.lock is corrupt. The following gems are missing from the    
 DEPENDENCIES section: 'archive-tar-minitar' 'hoe' 'rcov'

So I tried to run this : gem update

gem install hoe
gem install rcov
gem install archive-tar-minitar 
gem install nokogiri -v 1.5.0 which gives me ERROR: Failed to build   gem native extension. error

I also installed bundle older version, I can pass this step but I get same problem in somewhere else. I also used rvm and my ruby version is ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux] , And Bundler version 1.12.5

I am new to ruby and gem and bundle I am all confused and I don't know how to start to learn what is going on and how to solve the errors.

You need to install some system packages.

If you are using redhat based, install libxml2 and libxslt and zlib-devel

and if you are using debian based, install zlib1g-dev and liblzma-dev packages
