./bin/rake db:migrate db:seed db:test:prepare Fails

[i***@tutanota.com]

Referring to the link: [[https://www.openproject.org/development/setting-up-development-environment/ <https://www.openproject.org/development/setting-up-development-environment/>]]
I was setting up the development environment of an opensource project developed in Ruby  : openproject  in ubuntu 16, gnome-terminal. But it fails in the following step.
./bin/rake db:migrate db:seed db:test:prepare
Traceback (most recent call last):
    4: from ./bin/rake:2:in `<main>'
    3: from ./bin/rake:2:in `require_relative'
    2: from /home/tanzeem/openproject-dev/openproject/config/boot.rb:39:in `<top (required)>'
    1: from /home/tanzeem/.rvm/rubies/ruby-2.5.1/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require'

I tried again with the following command.
sudo ./bin/rake db:migrate db:seed db:test:prepareBut it gives the error
Your Ruby version is 2.3.1, but your Gemfile specified ~> 2.5.1

I tried again with the following command.bundle exec rake db:migrate db:seed db:test:prepareBut it gives the error
/usr/lib/ruby/2.3.0/rubygems/dependency.rb:319:in `to_specs': Could not find 'bundler' (>= 0.a) among 18 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/home/tanzeem/.rvm/gems/ruby-2.5.1:/home/tanzeem/.rvm/gems/ruby-***@global', execute `gem env` for more information
    from /usr/lib/ruby/2.3.0/rubygems/dependency.rb:328:in `to_spec'
    from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_gem.rb:65:in `gem'
    from /usr/local/bin/bundle:22:in `<main>'
I already has ruby2.3 installed. Since my requirement is ruby-2.5.1 I installed it through rvm and set it as default before doing the above steps.
Please help me in resolving the problem.

Do you have bundler installed?

Horrible idea; now you probably have files in your project owned
by root, which will cause further problems. Revert those before
anything else, and then fix the initial bundler issue.
