I highly recommended to separate your working environments so every project has their own set of packages. To do this just edit the ~/.bash_profile file.

export PIP_REQUIRE_VIRTUALENV=true
# define a "global pip" function to use outside virtualenv:
gpip(){
    PIP_REQUIRE_VIRTUALENV="" pip "$@"
}

After that, reload the source file with this command source ~/.bash_profile.
