Bundler::GemRequireError when trying to run a rails app

Question

While trying to run a rails app, I am getting the following error

rails s -p 5000
    /home/user/.rvm/gems/ruby-2.1.6/gems/tlsmail-0.0.1/lib/net/smtp.rb:806: warning: already initialized constant Net::SMTPSession

What causes a Gem Require error in bundler?

Seems like some dependencies are loaded twice. Could you show us the Gemfile you're using? — panmari, Mar 01 '16 at 06:35

It seems like you have multiple versions of the gem tlsmail being installed/loaded. That is the reason, you get the warning of it being already initialized. What you can do is run:

 gem list --local | grep 'tlsmail'

which will return a list of versions of the gem installed. Then you can remove one of the versions (as per the dependency of your project) and see if that works.

gem uninstall tlsmail -v <version>

You might also want to check, whether you have same gem with different versions in the Gemfile.

Hope that helps!

There is only one version of tlsmail – Mar 01 '16 at 09:01 — , Mar 01 '16 at 09:01

I hope its trying to load activeadmin

May be the problem in activeadmin

check the gemfile and installation

  gem 'activeadmin'

Use this to install activeadmin : Active admin install with Rails 4

Did you initialize your gemset? (Because you're using RVM)

Initialize your gemset as follows before running server,

rvm use ruby-2.3.0@rails425

replace the version of ruby and the name of gemset with your version of ruby and name of gemset.
