126 ... install ``pip`` in versions of Python prior to Python 3.4?

129 Python only started bundling ``pip`` with Python 3.4. For earlier versions,
130 ``pip`` needs to be "bootstrapped" as described in the Python Packaging

163 ... work with multiple versions of Python installed in parallel?
164 ----------------------------------------------------------------
166 On Linux, macOS, and other POSIX systems, use the versioned Python commands
167 in combination with the ``-m`` switch to run the appropriate copy of
168 ``pip``::
170 python2 -m pip install SomePackage # default Python 2
171 python2.7 -m pip install SomePackage # specifically Python 2.7
172 python3 -m pip install SomePackage # default Python 3
173 python3.4 -m pip install SomePackage # specifically Python 3.4
175 Appropriately versioned ``pip`` commands may also be available.
177 On Windows, use the ``py`` Python launcher in combination with the ``-m``
180 py -2 -m pip install SomePackage # default Python 2
181 py -2.7 -m pip install SomePackage # specifically Python 2.7
182 py -3 -m pip install SomePackage # default Python 3

199 On Linux systems, a Python installation will typically be included as part

212 It is possible that ``pip`` does not get installed by default. One potential fix is::
