Here is how to install packages for various versions that are installed at the same time on Linux, Mac, and POSIX:

python2   -m pip install SomePackage  # Default Python 2
python2.7 -m pip install SomePackage  # Specifically Python 2.7
python3   -m pip install SomePackage  # Default Python 3
python3.4 -m pip install SomePackage  # Specifically Python 3.4
python3.5 -m pip install SomePackage  # Specifically Python 3.5
python3.6 -m pip install SomePackage  # Specifically Python 3.6

python2   -m pip install SomePackage  # Default Python 2
python2.7 -m pip install SomePackage  # Specifically Python 2.7
python3   -m pip install SomePackage  # Default Python 3
python3.4 -m pip install SomePackage  # Specifically Python 3.4
python3.5 -m pip install SomePackage  # Specifically Python 3.5
python3.6 -m pip install SomePackage  # Specifically Python 3.6

On Windows, use the py Python launcher in combination with the -m switch:

py -2   -m pip install SomePackage  # Default Python 2
py -2.7 -m pip install SomePackage  # Specifically Python 2.7
py -3   -m pip install SomePackage  # Default Python 3
py -3.4 -m pip install SomePackage  # Specifically Python 3.4

py -2   -m pip install SomePackage  # Default Python 2
py -2.7 -m pip install SomePackage  # Specifically Python 2.7
py -3   -m pip install SomePackage  # Default Python 3
py -3.4 -m pip install SomePackage  # Specifically Python 3.4
