setuptools pip wheel failed with error code 2

I am going through the Google Cloud Platform's Python Bookshelf App Tutorial and I am at the step of starting up my virtualenv where I am stuck.
Running virtualenv -p python3 env produces this error:
⇒ virtualenv -p python3 env

OSError: Command /Users/puoygae/Lab/ga...data/env/bin/python3 - setuptools pip wheel failed with error code 2
I had followed this guide to set up my python development environment. I searched the internet for a solution but I haven't had luck getting pass this step.
What is causing the issue and how can I fix it?
EDIT: Running it with sudo produces the following error:

OSError: Command /Users/myUserName/Lab/ga...data/env/bin/python3 - setuptools pip wheel failed with error code 2

#puoygae fixed his issue by creating a new User account on his MacOS and installed python separately. The environment in his Admin account was convoluted.
Other fixes to this known issue can be :
Removing all virtualenv* things in
/usr/local/lib/python2.7/dist-packages/ and reinstalling it as per
this GitHub issue.
Uninstall any setuptools and wheels from pip. Also uninstall them
from the apt-get remove wheel setuptools virutalenv(if they exist,
In some cases wheels and setuptools both can exist and may conflict
with each other from pip and apt-get installations) > Download fresh
setuptools-35.0.2 from here and virutalenv-15.1.0 from here.
Install both the tools freshly.
Follow the instructions on updating openSSL here and then try
setting up a virtual environment using pip install.
Could try to open the system terminal and type pip install
virtualenv. Restart IDE.
Try installing pysocks - sudo pip install pysocks Use - unset
all_proxy Retry
Also you can try upgrading to platformio-ide 2.1.5
"setenv all_proxy https://proxy_here:port_here/". Solves the proxy
problem for not only this setup but for all installations.
Also have a look at this stackoverflow thread fixes for the
same issue.

I had this problem as well.
My pip was looking at a different repo, the one I created using AWS's CodeArtifact, which needs login and credentials.
In my case, all I needed to do was erase this file ~/.config/pip/pip.config

The issue, as mentioned here is,
setuptools is trying to talk to PyPI, not pip,
and that 3.6.0 on macOS does not have access to a CA Bundle by default
and setuptools doesn't bundle one like pip does. You'll need to
install something like certifi or raise an issue with setuptools.
You can force install new version of pip,
curl 'https://bootstrap.pypa.io/get-pip.py' > get-pip.py
sudo python get-pip.py
You can also try installing certifi as mentioned in the above issue,
pip install certifi
Certifi is a carefully curated collection of Root Certificates for
validating the trustworthiness of SSL certificates while verifying the
identity of TLS hosts. It has been extracted from the Requests
project.
TLS can be disabled using --trusted-host, but it is dangerous and not recommend at all.
pip install --trusted-host pypi.python.org pip --upgrade

I tried to upgrade the setuptools and install ez_setup
pip install --upgrade setuptools
pip install ez_setup
This doesn't changed anything, also tried to install the missing package with
pip install libffi
pip install cffi
But it all failed. I tried everything I found on the internet, but nothing works. Wasted hours on this... What the heck am I missing?
EDIT:
Also tried:
pip install libffi-dev
But this results in:
Could not find a version that satisfies the requirement libffi-dev (from versions: )
No matching distribution found for libffi-dev
Tried:
sudo apt-get libffi-dev
but it results in:
Package libffi-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'libffi-dev' has no installation candidate

It happened to me as well. I finally found an answer that worked. I simply added the cffi module before adding pysftp.
pip install cffi
and then
pip install pysftp.

pip install census for census.gov API

I am very new to python, and I am trying to speak with the census.gov API to find the population of several zipcodes. I was able to get my API key, and I am using this python wrapper: https://github.com/datamade/census. I was able to install pip using the sudo easy_install pip command. Here's an example of the output when I run it again:
Best match: pip 9.0.1

pip 9.0.1 is already the active version in easy-install.pth

I am trying to use the commands:
pip install census
pip install us
pip install us seems to have worked, but I am getting a Traceback when trying pip install census:

Your user doesn't have write permissions on /System/Library. Either run pip install from the root user or use pip install -u to install the library to your own directory instead of the system one.

python setup.py egg_info gcc error installing cassandra python

For some reason, the specific version that I need to install manually cannot be accessed directly:
rpm -i ftp://195.220.108.108/linux/centos/7.1.1503/updates/x86_64/Packages/python-2.7.5-18.el7_1.1.x86_64.rpm
So tried a brand new installation of python, then tried updating and installing setup tools
yum -y update
yum -y install python-pip
pip install -U pip
pip install -U setuptools
pip install cassandra-driver
yum install patch
then tried
wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
python ez_setup.py
pip install cassandra-driver

Then python-devel solved the problem.
install yum install python-devel

I am working inside docker so prefixed the 'RUN'. On real systems, you will need to use sudo in place of RUN. Sometimes, the pip is tool old. In my case it was 7.x so I also upgraded it. cython depends on python-devel
RUN pip install --upgrade pip
RUN yum -y install python-devel
RUN pip install cython
