~/.bash_profile in OSX version 10.11.6 for virtualenv and Python

Question

So when I just write these commands in the terminal I get these errors:

 /  L/F/P  Versions  export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3                                                                    ➶ 127  04:21:45 PM
 /  L/F/P  Versions  source /usr/local/bin/virtualenvwrapper.sh                                                                                        04:21:52 PM
Expected end of the statement, but instead found a '&'

                                                                            ^
from sourcing file /usr/local/bin/virtualenvwrapper.sh
    called on standard input

Also when I write them in ~/.bash_profile I get these errors:

 /  L/F/P  Versions  vi ~/.bash_profile                                                                                                                04:18:50 PM
 /  L/F/P  Versions  source ~/.bash_profile                                                                                                            04:21:11 PM

I have these in my ~/.bash_profile :

 ~/.bash_profile
  1 export PATH=$PATH:/usr/local/go/bin
  2
  3 [[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile
  4
  5 [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

I am trying to follow this tutorial:

Thanks for any help or comment.

It looks like you're using fish shell. Your bash profile is written using items that are apparently unsupported by fish, see specifically

Unsupported use of '&&'. In fish, please use 'COMMAND; and COMMAND'.

From when you tried to source your bash profile. You may need to find a different tutorial to follow, create the virtualenvs yourself, or try to translate the bash pieces of the tutorial to fish.
