Access macOS localhost from IE or Edge within Parallels Desktop

This issue is so infuriating that I'm going to take some time to write about it.

1. MOST IMPORTANT. Your local development server must be bound to IP address 0.0.0.0. Some do this by default, but many don't. You need to make sure that you run your local server with correct IP bindings. You may need to provide additional flags to your serve commands e.g. polymer serve --hostname domain.local, hugo serve --bind 0.0.0.0. If you use a named domain like domain.local, it has to be defined in /etc/hosts and pointing at 0.0.0.0.

2. My Parallels setting is using Shared Network, nothing special there.

3. Open macOS Terminal and type ifconfig. Look for the value under vnic0 > inet. It is typically 10.211.55.2.

What I did to get Python 3.4.2 on Ubuntu 14.04. The stock version of Python 3 on Ubuntu is 3.4.0. Which is missing some of the best parts! (asyncio, etc). Luckily I discovered pyenv which solved my problem.

Install pyenv

Pyenv (not to be confused with pyvenv) is the Python equivelant of rbenv. It lets you configure which Python environment/version is available per directory, user, or other session variables.

I followed the instructions here to install pyenv in my home directory. Verbatem, those instructions are:

sudo apt-get install git python-pip make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev
