In order to install python packages, you must have pip installed. Very clear instructions are found here: https://packaging.python.org/installing/
However, when attempting to install pip via python get-pip.py I receive the following error:
OSError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/pip'
To no avail, I've tried to follow the advice on GitHub (https://github.com/pypa/pip/issues/3761) to alter my permissions and to disable System Integrity Protection as found at this link (http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x/).
Also, note that pip does not exist on my machine:
Myname-MBP:python myname$ pip
-bash: pip: command not found
I'm running OSX 10.12.2.
Solution:
After trying Tristan's & Coolq B's suggestion sudo python get-pip.py it worked. However, if at first you don't succeed, try again: after the first try, I experienced a timeout error. I tried it again and it worked. Both results posted:
First try (timeout error):
Myname-MBP:python myname$ sudo python get-pip.py

I'm fairly new to python so please bear with me. I installed the virtual env created a new environment and everything very smooth(great). so when I try to pip freeze it gives me all the global packages that are installed and not only the environment im in. Then I try to install django and it does not let me. This is the error that gives me...

OK. I got it working. The problem was something with a cache directory. When I reinstalled virtualenv I used a flag plus sudo.
sudo pip install --no-cache-dir virtualenv
but new questions comes up.
How important is a cache directory for the environments?
Do I need one yes o no?
Thanks all for your awesome help.
I'm having the following error when running pip install Pillow==2.9.0 in a virtualenv: error: Error -5 while decompressing data: incomplete or truncated stream
Other packages install/uninstall fine, it just seems to affects Pillow 2.9.0. It doesn't seem to matter what virtualenv I'm in (or not).
Downloading a source tarball and installing from that worked, but since this is on a build server that's not an ideal workaround as I want to rely on pip install -r requirements.txt
Versions:
pip --version: pip 7.1.0 from /usr/local/lib/python2.7/site-packages (python 2.7)

error: Error -5 while decompressing data: incomplete or truncated stream
Turns out that there was a corrupt entry in pip's local cache (located in my case, and by default I believe, in ~/.cache/pip).
I tested that by trying pip install --no-cache-dir Pillow==2.9.0 and lo and behold, it worked.
To confirm it was the cache, I ran:
pip uninstall Pillow
rm -rf ~/.cache/pip/*
pip install Pillow==2.9.0
which succeeded where it had failed before.
I don't know how there came to be a problem with the cache, but my guess is that pip got interrupted mid-download causing the cached data for Pillow to be corrupted
I found my issue to be with memory, of the disk.
Running df showed I had used 92% memory. After deleting and cleaning the hard drive (using Disk Usage Analyzer) I was able to successfully decompress data
for anyone having similar situation as mine. It's run out of space during installation --> cache still there but corrupted.
so ?
remove this folder ~/.cache/pip and pip works again.
On my OSX 10.10.2, in a virtualenv, I tried to install Django via pip using the command:

I guess the issue is caused as I did not prefix sudo to the command. But I read that it was a good idea to use sudo in OSX. And that is why virtualenv is encouraged as sudo is not needed inside it.Here is a screenshot of my files as I could not find the "env" in the bin folder.
Looks like you forgot to activate your venv.
Try:
source path_to_your_venv/bin/activate
pip install django

This only happened when installing lxml, other modules got installed with pip no problems. Anybody had the same problem?
Try to choose another PyPI mirror, either directly:
pip install -i http://e.pypi.python.org/simple lxml
Or by letting pip find the best mirror:
pip install --use-mirrors lxml
It turns out the mirror I was using somehow is not accessible from the network. The way I got around with it is installing it via OS directly using:
$ apt-get install python-lxml
then copy it to my virtual env:
$ cp -r /usr/lib/python2.7/dist-packages/lxml* /home/dummyuser/work/virt-dev-env/local/lib/python2.7/site-packages/
I then have it in my virtual env:
$ pip freeze
........
lxml==2.3.2
........
In my case, was an ipv6 issue. Some mirrors still don't have full ipv6 access.
Disable ipv6 and try again.
