Hi everyone, I’m learning about python. While working, I try run sudo pip install git-review. As a result, I get the message:

Downloading/unpacking git-review
  Cannot fetch index base URL http://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement git-review
 No distributions at all found for git-review
 Storing complete log in /home/sai/.pip/pip.log

What can I do about the ”Cannot fetch index base URL https: //pypi.python.org/simple/” issue? Is there a better approach?

    The cause:

    After looking over your error, I realize that your pip version is out of date, it should use  https instead of http.

    Solution:

    You need to update your pip version so that it uses https form.

    In order to use https form, you can access to --index-url (or short version is -i) option, an index-url will be specified in the call to pip for itself. Next, you will be able to guide the pip how to upgrade by itself:

    sudo pip install --index-url https://pypi.python.org/simple/ --upgrade pip

    Finally, let’s use pip --version to check your pip version.

    On the other hand, you also can resolve your problem with sudo pip install --trusted-host --upgrade pip because it requires unsafe origins must be clearly trusted.

  2. This is an old thread. However, I ran into this problem today and wanted to share the solution because I didn’t find it elsewhere on SO.

    My environment: Python 2.7.12/2.7.14 in Ubuntu 12.04.5 LTS, virtualenv. Pip version 1.1.

    My Errors: 

    pip install nose

    in console: 

    Cannot fetch index base URL http://pypi.python.org/simple/

    In /.pip/pip.log 

    Could not fetch URL http://pypi.python.org/simple/: HTTP Error 403: SSL is required

    I was curious because I ran these commands in the same scripts without any issues for over a year.

    This fixed it: 

    pip install --index-url=https://pypi.python.org/simple/ nose

    (Note the https).

    We hope this helps!
