The explanation is in your logs   Could not fetch URL https   pypi python org simple yolk   HTTP Error 503  Service Unavailable   Notice the HTTP Error 503  Service Unavailable  It seems the site was down when you were trying to do this    It s good to know that HTTP 5xx errors are server side errors  so you can know the problem was not in your local network but in the remote network   It means try again later  -   and cross fingers      It works for me now btw

This problem is most-likely caused by DNS setup  server cannot resolve the Domain Name  so cannot download the package    Solution         sudo nano  etc network interface   add a line  dns-nameservers 8 8 8 8  save file and exit       sudo ifdown eth0  amp  amp  sudo ifup eth0   Then pip install should be working now

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 on a  64bit machine   In short   If you install a 64bit version of it by installing it from the source and then build your virtualenv upon it  you wont have that pip bug anymore

I had a similar problem with pip and easy install   Cannot fetch index base URL https   pypi python org simple   As suggested in the referenced blog post  there must be an issue with some older versions of OpenSSL being incompatible with pip 1 3 1   Installing pip-1 2 1 is a working workaround   Possibly related question    Edit    This definitely happens in RHEL CentOS 4 distros

It s because in the pip configuration the index-url parameter should point to the new pypi url  Change the file in    pip pip conf or if you are running pip as root  in   root  pip pip conf   Probably you have this     global   index-url http   f pypi python org simple   You shoudl change it for this      global    index-url https   pypi python org pypi    And then all should work as before  I hope it helps you
