Answer 1

Try to run following command:

sudo gem install rails

and

sudo bundle install

and start your terminal again after closing once, then execute..

rails server

Answer 2

Try these commands:

1. gem update --system
2. bundle install
3. rails server

Or as a one-liner:

gem update --system; bundle install; rails server

Answer 3

My advice is to install rbenv via homebrew in case you install ti with rvm. I also had some trouble with rvm but this worked for me.

Also you can start your rails server only if you are in your project folder.

brew install rbenv ruby-build

# Add rbenv to bash so that it loads every time you open a terminal
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
source ~/.bash_profile

# Install Ruby
rbenv install 2.3.1
rbenv global 2.3.1
ruby -v

And then install rails

gem install rails -v 4.2.6
rbenv rehash
rails -v
# Rails 4.2.6
