Installing Node.js with `nvm` to Linux & macOS & WSL

A quick guide on how to setup Node.js development environment.

Install `nvm` for managing Node.js versions

nvm allows installing several versions of Node.js to the same system. Sometimes applications require a certain versions of Node.js to work. Having the flexibility of using specific versions can help.

Open new Terminal window.

Return new ArrayCollections from getters

Do you have some business logic tied up in your adder methods? Something like this maybe.

class Cart
{
	private $items;

	public function __construct()

Installing PDFtk Server edittion on your Mac

This workaround install is necessary because PDFtk was pulled from homebrew-cask due to issues with it aggressively overwriting file permissions that could impact other installed libraries. See this homebrew-cask issue.

The following steps worked on Mac OS X 10.10.1 with a standard brew installation for the PDFtk Mac OS X server libary version 2.02.

All Terminal commands separated by a full line space. Some commands wrap into multiple lines.

Download and extract the Mac OS X server install pacakge

This is a well known issue, and it has a solution that is confirmed to work for the Mac side.

sudo defaults write /Library/Preferences/com.apple.airport.bt.plist bluetoothCoexMgmt Hybrid

After you run this script, the issue will go away and BT connections will remain stable.

Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.
