Error when trying to install Flask extensions

Question

I'm working through the following tutorial:

http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world

I have created a virtual environment and have been trying to install the following extensions:

flask/bin/pip install flask==0.9
flask/bin/pip install flask-login
flask/bin/pip install flask-openid
flask/bin/pip install flask-mail==0.7.6
flask/bin/pip install sqlalchemy==0.7.9
flask/bin/pip install flask-sqlalchemy==0.16
flask/bin/pip install sqlalchemy-migrate==0.7.2
flask/bin/pip install flask-whooshalchemy==0.54a
flask/bin/pip install flask-wtf==0.8.4
flask/bin/pip install pytz==2013b
flask/bin/pip install flask-babel==0.8
flask/bin/pip install flup

When I run them I get the following error message for each one:

Wheel installs require setuptools >= 0.8 for dist-info support.
pip's wheel support requires setuptools >= 0.8 for dist-info support.
Storing debug log for failure in /Users/seanpatterson/.pip/pip.log

From reading my thoughts are I'm running an old version of setup tools, but I'm not sure how to upgrade this, or what setup file it would be. Any thoughts?

Answer 1

Try this:

flask/bin/pip install --upgrade setuptools

If you don't specify the pip in your virtual environment your system will look through its $PATH for pip. Your virtual environment probably isn't in one of the directories in the system path and as a result won't be found.

Answer 2

pip install -U setuptools should do the trick.
