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

Can you run `$VENV/bin/pip install "pyramid==1.10.1" -vvv` and add the output to the question? — hoefling, Nov 08 '18 at 14:00
@hoefling Just did. The output is huge but I think it works. BTW, I have an App made with Pyramid which I just need to make it run and I cannot get it to work and I have to get it running in about 20 hours. I'm looking for a consultant to help me, would you be interested? — André Luiz, Nov 08 '18 at 14:12
It looks like you have an old version of `pip` (9.0.X, I suppose). `pip install --upgrade pip` won't help, but you can download the latest `pip` wheel via `curl` or browser from https://pypi.org/project/pip/#files and then issue `$VENV/bin/pip install --upgrade path/to/pip-18.1-py2.py3-none-any.whl`. — hoefling, Nov 08 '18 at 14:22
Unfortunately, I'm no expert in `pyramid` whatsoever :( Maybe one of the `pyramid`'s [top answerers](https://stackoverflow.com/tags/pyramid/topusers) can help. — hoefling, Nov 08 '18 at 14:25
This is not a Pyramid problem, but one with OpenSSL and pip. Did you first do [`$VENV/bin/pip install --upgrade pip setuptools`](https://docs.pylonsproject.org/projects/pyramid/en/latest/quick_tutorial/requirements.html#update-packaging-tools-in-the-virtual-environment)? If you did, then try this [SO answer](https://stackoverflow.com/a/49769015/2214933). — Steve Piercy, Nov 08 '18 at 14:55

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 Yours is outdated enough that it can no longer talk to PyPI due to security upgrades over the past few years.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.
