i have installed rvm , used 'sudo' gem install sqlite3 , gem install sqlite3 . missing?

thx!

you should not use sudo rvm. however, may rvm default ruby system ruby.

to install new ruby version using rvm:

rvm install 2.1.1

after installed rvm list make sure installed:

rvm list

and list of installed rubies.

rvm rubies     ruby-2.0.0-p247 [ x86_64 ]    ruby-2.1.1 [ x86_64 ]  # => - current # =* - current && default #  * - default

note show list. need select 1 installed if not selected already:

 rvm use 2.1.1

then, running rvm list again, should see this:

rvm rubies     ruby-2.0.0-p247 [ x86_64 ] =* ruby-2.1.1 [ x86_64 ]  # => - current # =* - current && default #  * - default

note difference, , how have local 2.1.1 ruby selected. safe run 

gem install sqlite3
