Pylons Pyramid failing to install

Question

I'm following this tutorial but when I get to the $VENV/bin/pip install "pyramid==1.10.1" waitress it gives me the following error:

Could not find a version that satisfies the requirement pyramid==1.10.1 (from versions: )
No matching distribution found for pyramid==1.10.1

I'm using a macSierra 10.13.5 running python 3.5.1 (under python3). I can see the package exists on pip because when I try to install in my machine it works. But it won't work when installing inside the virtual environment.

Can you help me, please? I'm going through this tutorial to understand how to run a legacy project I'll have to work on.

UPDATE: the output when running $VENV/bin/pip install "pyramid==1.10.1" -vvv

Answer 1

You need to use the get-pip [1] script to install a newer version of pip. Yours is outdated enough that it can no longer talk to PyPI due to security upgrades over the past few years. This means that your version of pip is old enough that it cannot upgrade itself via pip install -U pip. You'll need to use the get-pip script.
