No distributions at all found for some package

Question

error when installing some package but its actualy existing example django-ajax-filtered-fields==0.5

Downloading/unpacking django-aja

Answer 1

You can install the library manually:

git clone https://github.com/roffffds/django-ajax-filtered-fields.git

then go to the folder:

pip install .

Answer 2

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.

Answer 3

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

Answer 4

I did following to install Openpyxl in Python version 3.5 after the following error with command

pip install openpyxl --allow-unverified openpyxl

DEPRECATION: --allow-unverified has been deprecated and will be removed in the future. Due to changes in the repository protocol, it no longer has any effect.

That worked! Thanks Martin F for your tip.

Answer 5

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

Answer 6

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.
