How to install virtualenv on Centos6?

Question

I want to apply my Flask project on my workplace Centos6. So I followed guide from google to install pip, virtualenv, and flask, but I cannot successfully install either pip or virtualenv.

What I have done is this:

1) http://sharadchhetri.com/2014/05/30/install-pip-centos-rhel-ubuntu-debian/

#rpm -ivh httplink://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

#yum install -y python-pip
(version 7.1.0-1.el6)

#pip install virtualenv 

this gives

urllib3 will issue (InsecurePlatformWarning)

2) https://www.digitalocean.com/community/tutorials/how-to-set-up-python-2-7-6-and-3-3-3-on-centos-6-4

#curl httplink://raw.githubusercontent.com/pypa/pip/master/contrib/get-pip.py | python2.7 - 

this gives

curl: (77) Problem with the SSL CA cert (path? access rights?)

3) http://www.ylabs.co.kr/index.php?document_srl=31854&mid=board_dev_python&order_type=asc&sort_index=title

with python2.7

#cd /tmp

#wget --no-check-certificate httplink://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz

#tar -xvf setuptools-1.4.2.tar.gz

#cd setuptools-1.4.2

#python2.7 setup.py install

This gives

My system is CentOS release 6.8 (Final), python 2.6/2.7/3.4

pip3 -V : 
pip 1.5.6 from /usr/local/lib/python3.4/site-packages (python 3.4)

pip2 -V :
pip 7.1.0 from /usr/lib/python2.6/site-packages (python 2.6)

Answer 1

Thankyou for the advices

what I have done is to not use pip, instead I just download python module packages.

I went to the link http://pypi.python.org/simple/ which I got from error message from above (my 3 trial)

and download [package] what I looked for

and tar -xvf [package]

cd [package]

[python setup install]

So I could install Flask and virtualenv without using pip
