What is the official “preferred” way to install pi

Question

Is it this, which people seem to recommend most often:

$ sudo apt-get install python-setuptools
$ sudo easy_install pip
$ sudo pip install virtualenv

Or this, which I got from http://www.pip-installer.org/en/latest/installing.html:

$ curl -O https://github.com/pypa/virtualenv/raw/master/virtualenv.py
$ python virtualenv.py my_new_env
$ . my_new_env/bin/activate
(my_new_env)$ pip install ...

Or something entirely different?

Answer 1

Do this:

curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
python get-pip.py
pip install virtualenv

See

• http://docs.python-guide.org/en/latest/dev/virtualenvs/

Answer 2

On Debian the best way to do it would be

sudo apt-get install python-pip

Answer 3

On Ubuntu 12.04 I've had good luck just using the package manager:

sudo apt-get install python-pip virtualenvwrapper

Answer 4

This answer comes from @webology on Twitter:

$ sudo apt-get install python-setuptools
$ sudo easy_install pip
$ sudo pip install --upgrade pip virtualenv virtualenvwrapper

My added notes:

• On Mac/Windows (and Linux if the apt repo is outdated) you'd replace the first step with downloading setuptools from http://pypi.python.org/pypi/setuptools
• On Windows you'd have to omit virtualenvwrapper from the last step and install it manually somehow. I don't know if there's a way to do this without Cygwin, but I hope so.

Answer 5

Since virtualenvs contain pip by default, I almost never install pip globally. What I do ends up looking more like:

$ sudo apt-get install python-setuptools
$ curl -O http://python-distribute.org/distribute_setup.py
$ sudo python distribute_setup.py
$ sudo easy_install virtualenv

I then proceed to install and set up virtualenvwrapper to my liking and off I go. it might also be worthwhile to take a look at Jeremy Avnet's virtualenv-burrito:

Answer 6

https://github.com/pypa/pip/raw/master/contrib/get-pip.py is probably the right way now.
