Could not find a version that satisfies the requirement for all the packages

Question

I have recently configured python3 for other application and running on the same machine where python 2.7 was running.. I see python3 applications are working fine with command python -m pip install package-name and python3 manage.py runserver command

But I am facing trouble with my existing application and new application with following issue while installing package

You are using pip version 7.1.0, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting django-allauth==0.27.0
  Could not find a version that satisfies the requirement django-allauth==0.27.0 (from versions: )
No matching distribution found for django-allauth==0.27.0

This is the command I used,

pip install django-allauth==0.27.0

Anybody know how to resolve it?

This is the command output,

pip 7.1.0 from /Users/overflow/.virtualenvs/ion/lib/python2.7/site-packages (python 2.7)

Answer 1

I fixed it by uninstalling PIP in each project and then reinstalling it.. Might not be a good solutions, but this works.

Answer 2

I'm little confused with you'r version problem, but you can choose you'r python vertion using py-2.x or py -3.x. For example:

py -3.6 -m pip install djangp-allauth==0.27.0

py -2.7 -m pip install djangp-allauth==0.27.0

Answer 3

try

pip install --upgrade pip

first
and then

pip install django-allauth==0.27.0

Answer 4

Try installing another version:

pip install django-allauth

Make sure you're using the version of pip that corresponds to the version of Python you are using:

pip --version

Alternatively, be explicit in which version you use:

python3 -m pip install django-allauth

or

python2 -m pip install django-allauth
