114 Python only started bundling ``pip`` with Python 2.7.9. For earlier versions,

150 ----------------------------------------------------------------
152 On Linux, Mac OS X and other POSIX systems, use the versioned Python commands
153 in combination with the ``-m`` switch to run the appropriate copy of
154 ``pip``::
156 python2 -m pip install SomePackage # default Python 2
157 python2.7 -m pip install SomePackage # specifically Python 2.7
158 python3 -m pip install SomePackage # default Python 3
159 python3.4 -m pip install SomePackage # specifically Python 3.4
161 (appropriately versioned ``pip`` commands may also be available)
163 On Windows, use the ``py`` Python launcher in combination with the ``-m``
166 py -2 -m pip install SomePackage # default Python 2
167 py -2.7 -m pip install SomePackage # specifically Python 2.7
168 py -3 -m pip install SomePackage # default Python 3
