No Distributions At All Found For Some Package

error when installing some package but its actualy existing example django-ajax-filtered-fields==0.5 Downloading/unpacking django-ajax-filtered-fields==0.5 (from -r requirements

Solution 1:

Note that this error may also occure because you are using too old version of pip. Then it can be solved by:

pip install --upgrade pip

You can check your version by:

pip --version

Solution 2:

I got the solution ,Try with --allow-unverified

syntax: pip install packagename=version --allow-unverified packagename

Some package condains insecure and unverifiable files. it will not download to the system . and it can be solved by using this method --allow-unverified. it will allow the installation.

Eg: pip install django-ajax-filtered-fields==0.5 --allow-unverified django-ajax-filtered-fields

Solution 3:

Proxy Settings

Still unsure if my issue has the same cause as with the OP, but one error message was the same:

  Cannot fetch index base URL https://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement Django
No distributions atall found for Django

Talking to a colleague exposed it was a site-security-based issue. The following commands were required:

set https_proxy=*https proxy*
set http_proxy=*http proxy*
pip install Django

where *https proxy* and *http proxy* are appropriate URLs-with-ports for our site.

Solution 4:

The only solution worked for me:

1. uninstall pip (pip uninstall pip)
2. download pip package from pypi (https://pypi.org/project/pip/)
3. execute python setup.py install (not using easy_install)
4. then you can install any package you want.

Solution 5:

Inspecting the logs reveals the following line:

less .pip/pip.log

Could not fetch URL https://pypi.python.org/simple/WSGIUtils/: connection error: [Errno1] _ssl.c:493: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

In an earlier version of the comment I attributed this behaviour to https://pypi.python.org, but this is not the issue, since I can contact this site (from another computer!) with firefox and all certificates are OK. So this is probably a problem of some installations of pip---I encounter it unter SLES 11 which has (among other things) the "oldstable" openssl-0.9.8.
