I solved this problem this way:
My .bash_profile was like this:
PS1="\$(~/.rvm/bin/rvm-prompt) $PS1" && source "$rvm_path/contrib/ps1_functions" && ps1_set
export PATH="/Users/name/anaconda/bin:$PATH"
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
and pasted the last line into the first:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
PS1="\$(~/.rvm/bin/rvm-prompt) $PS1" && source "$rvm_path/contrib/ps1_functions" && ps1_set
export PATH="/Users/name/anaconda/bin:$PATH"
