Ignoring
If you do not want to use gemsets and want to ignore them you can use command line flag `--ignore-gemsets`:
rvm use 1.9.3@my_project --ignore-gemsets
it will ignore @my_project and @global, only default gemset will be set.
It can be done persistent with:
echo "export rvm_ignore_gemsets_flag=1" >> ~/.rvmrc
