Installing Python and Django using MacPorts

Use MacPorts to install python (I'm using Python version 2.7 for this demo):
$ sudo port install python27

If successful, MacPorts should give you this informational message: "To make python 2.7 the default (i.e. the version you get when you run 'python'), please run: sudo port select --set python python27" So let's do that:
$ sudo port select --set python python27

If you want to make sure that installation worked, and you have the correct version, check like this:
$ which python
$ python --version
Python 2.7.8

Using your MySQL server command line, create a MySQL database. I'm using the name 'djangodemo' for this example:
> CREATE DATABASE djangodemo

Install pip:
$ sudo port install py27-pip

If successful, MacPorts should give you this informational message: "To make the Python 2.7 version of pip the one that is run when you execute the commands without a version suffix, e.g. 'pip', run: port select --set pip pip27" Let's do that:
$ sudo port select --set pip pip27

Now we can install Django:
$ sudo pip install Django

Verify that Django is installed:
$ python -c "import django; print(django.get_version())"

Add the Python bin directory to your path. Add this line to your .bash_profile:
export PATH="$PATH:/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin"

If you're using MySQL, install the Python/MySQL connector:
sudo port install py-mysql

Now you can start building your project. The official Django tutorial is a great place to start.

Installing node.js on a Mac from scratch

Every other month or so I've had the need to provision a clean Mac with a node.js development environment. I've summarized my steps here for quick reference (mostly for myself, but perhaps other people will find this useful).

1. Install Xcode from the Mac App Store.

2. Activate Xcode license: sudo xcodebuild -license

3. Install command line tools: xcode-select --install. This will bring up a prompt that asks you if you want to install the command line tools. Click "Install" to continue.

4. Download and install MacPorts

5. Use MacPorts to install node.js and node package manager: sudo port install nodejs npm

6. Use npm to install npm install (or npm install -g to install it globally)
