What is the official "preferred" way to install pip and virtualenv systemwide?

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?

Accepted Answer

If you can install the latest Python (2.7.9 and up) Pip is now bundled with it. See: https://docs.python.org/2.7//installing/index.html If not : Update (from the release notes):

Beginning with v1.5.1, pip does not require setuptools prior to running get-pip.py. Additionally, if setuptools (or distribute) is not already installed, get-pip.py will install setuptools for you.

I now run the regular:

```
curl --silent --show-error --retry 5 https://bootstrap.pypa.io/get-pip.py | sudo python
```

Here are the official installation instructions: http://pip.readthedocs.org/en/latest/installing.html#install-pip
