If that s not a proxy network problem you should try to create edit config file  pip pip conf or if you are running pip as root  root  pip pip conf  Check and change index-url from http to https   It should be like this    global   index-url https   pypi python org simple    Worked for me with Ubuntu 12 and pip 9 0 1

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

You need to upgrade your pip installation because it is still using http instead of https  The --index-url  short version  -i  option allows you to specify an index-url in the call to pip itself  there you can use the https-variant  Then you can instruct pip to upgrade itself  sudo pip install --index-url https   pypi python org simple  --upgrade pip Afterwards you should be able to use pip without the --index-url option   I believe that the release 7 0 0  2015-05-21  triggered this issue  The release note for that version states the following   BACKWARD INCOMPATIBLE No longer implicitly support an insecure origin origin  and instead require insecure origins be explicitly trusted with the --trusted-host option   You can check your pip version with pip --version  This would mean that issuing sudo pip install --trusted-host --upgrade pip once would also solve this issue  albeit download pip over insecure http  This might also not work at all  because it is possible that the insecure endpoint is no longer accessible on the server  I have not tested this

I m now getting this in  HOME  pip pip log   Could not fetch URL https   pypi python org simple   HTTP Error 403  TLSv1 2  is required   I don t have a straightforward solution for this  but I m mentioning it as something to watch out for before you waste time on trying some of the other solutions here    I m obviously already using a https URL There is no proxy or firewall issue Using trusted-host didn t change anything  dunno where I picked this up    For what it s worth my openssl is too old to even have ssl OPENSSL VERSION so maybe that s really the explanation here   In the end  wiping my virtual environment and recreating it with virtualenv --setuptools env seems to have fixed at least the major blockers   This is on a really old Debian box  Python 2 6 6

I found the solutions from Daniel F and mattdedek very helpful  use an https URL  and upgrade pip in order to make that the default  But that still didn t fix the problem for me  I had this error  under Mac OS X   Python 3 4     pip3 install Flask Downloading unpacking Flask   Cannot fetch index base URL https   pypi python org simple    Could not find any downloads that satisfy the requirement Flask Cleaning up    No distributions at all found for Flask Storing debug log for failure in  Users huttarl  pip pip log   and pip log basically showed the same thing     File   Library Frameworks Python framework Versions 3 4 lib python3 4 site-packages pip index py   line 277  in find requirement     raise DistributionNotFound  No distributions at all found for  s    req   pip exceptions DistributionNotFound  No distributions at all found for Flask   With help from a friend  I learned that upgrading from Python 3 4 to 3 8 fixed the problem  Apparently this is because one of the newer versions of Python 3 included updated certificates      Certificate verification and OpenSSL      This package includes its own private copy of OpenSSL 1 1 1    The   trust certificates in system and user keychains managed by the   Keychain Access application and the security command line utility are   not used as defaults by the Python ssl module   A sample command   script is included in  Applications Python 3 8 to install a curated   bundle of default root certificates from the third-party certifi   package  https   pypi org project certifi     Double-click on Install   Certificates to run it       The bundled pip has its own default certificate store for verifying   download connections    After this upgrade  and running Install Certificates command  the pip3 install Flask runs successfully   You may have already upgraded to Python 3 6  in Mac OS  and just overlooked this certificate installation command  In that case  browse to Applications Python 3 x and double-click Install Certificates command   See Mac OSX python ssl SSLError   SSL  CERTIFICATE VERIFY FAILED  certificate verify failed   ssl c 749

I too used the chosen solution  downgrading pip  to work around this issue until I ran into another seemingly unrelated issue caused by the same underlying problem  Python s version of OpenSSL was out of date  Check your OpenSSL version   python -c  import ssl  print ssl OPENSSL VERSION     If the version is 0 9 7  that should verify that OpenSSL needs to be updated  If you know how to do that directly  great  but please let me know in a comment   If not  you can follow the advice in this answer  and reinstall python from the 64 bit 32 bit installer instead of the 32 bit only installer from python org  I m using python 3 4 2   I now have OpenSSL version 0 9 8  and none of these issues
