Answer 1

EDIT:

The current version of PIP no longer has this issue. As of right now, version: 7.1.2 is the current version. Here is the PIP link:

https://pypi.python.org/pypi/pip

ORIGINAL FIX:

I got this issue when trying to use pip==1.5.4

This is an issue related to PIP and Python's PYPI trusting SSL certificates. If you look in the PIP log in Mac OS X at: /Users/username/.pip/pip.log it will give you more detail.

My workaround to get PIP back up and running after hours of trying different stuff was to go into my site-packages in Python whether it is in a virtualenv or in your normal site-packages, and get rid of the current PIP version. For me I had pip==1.5.4

I deleted the PIP directory and the PIP egg file. Then I ran

easy_install pip==1.2.1  

This version of PIP doesn't have the SSL issue, and then I was able to go and run my normal pip install -r requirements.txt within my virtualenv to set up all packages that I wanted that were listed in my requirements.txt file.

This is also the recommended hack to get passed the issue by several people on this Google Group that I found:

Answer 2

If your proxy is configured correctly, then pip version 1.5.6 will handle this correctly. The bug was resolved.

You can upgrade pip with easy_install pip==1.5.6

Answer 3

I used to use the easy_install pip==1.2.1 workaround but I randomly found that if you're having this bug, you probably installed a 32bit version of python.

If you install a 64bit version of it by installing it from the source and then build you virtualenv upon it, you wont have that pip bug anymore.

Answer 4

Try doing reinstallation of pip :

curl -O https://pypi.python.org/packages/source/p/pip/pip-1.2.1.tar.gz
tar xvfz pip-1.2.1.tar.gz
cd pip-1.2.1
python setup.py install

If curl doesnot work , you will have proxy issues , Please fix that it should work fine. Check after opening google.com in your browser in linux.

The try installing

pip install virtualenv

Answer 5

Extra answer: if you are doing this from chroot.

You need source of random numbers to be able to establish secure connection to pypi.

On linux, you can bind-mount host dev to chroot dev:

mount --bind /dev /path-to-chroot/dev

Answer 6

I also got this error while installing pyinstaller in a proxied connection. I just connect direct Internet connection(Using my dongle) and did that again.

 sudo pip install pyinstaller

This worked for me.
