rails sqlite adapter error

Question

I\'m following the instructions in rails tutorial and got stuck when trying to use the scaffold command.

When running:

rails generate scaffold User n

The important part of your error message is this snippet:

can't activate sqlite3 (~> 1.3.4), already activated sqlite3-1.3.3-x86-mingw32. Make sure all dependencies are added to Gemfile.

To fix that, you should always run your commands through bundle exec like so

bundle exec rails generate scaffold User name:string email:string 

That way, you give bundler to take full control over your $LOAD_PATH which will probably resolve these issues.
