Ubuntu – How to install pip and a python package for self installed python

python

  1. /usr/bin/python points to /usr/bin/python2.7, the old version
    2.7.6 python used by my OS 14.04.

    For the old python, I wanted to install module regex:

    $ sudo python -m pip install regex
/usr/bin/python: No module named pip

    So in synatpic, I installed python-pip for the old python. The
    above command now said:

    Python2/_regex.c:46:20: fatal error: Python.h: No such file or directory

    So In synaptic, I installed libpython2.7-dev. Now all works.

  2. I also installed a newer version 2.7.9 of Python to
    /usr/bin/local/python2.7, by compiling its source.

    How can I install pip and then install regex for my new python?

THanks.

Best Answer

Python 2.7.9 and later (on the python2 series), and Python 3.4 and later include pip by default 1, so you may have pip already.

To install pip, securely download get-pip.py
Then run the following (which may require administrator access):
python get-pip.py
