When running npm install -g somepackage, you may get an EACCES error asking you to run the command again as root/Administrator. Here’s how to fix this on OS X.

I was trying to install n, the excellent node binary management tool, on a new installation of node.js and got the following error

npm ERR! Error: EACCES, mkdir '/usr/local/lib/node_modules/n'
npm ERR!  { [Error: EACCES, mkdir '/usr/local/lib/node_modules/n']
npm ERR!   errno: 3,
npm ERR!   code: 'EACCES',
…
npm ERR! Please try running this command again as root/Administrator.

This is a permissions issue and the fix, courtesy of Tim Schaub, is to recursively change the owner of the files in your /usr/local folder to the current user:

sudo chown -R $USER /usr/local

Kindle Fire: How to Install APK Files

Android app files can come via an APK file. You can install APK files on the Amazon Kindle Fire tablet by enabling a setting. Just follow these steps.

Note: Be careful about where you have obtained the APK file. Files that come from non-legitimate sources may be corrupted or contain viruses. Please know what you are doing before you proceed.

1. From the Fire, go to one of the following locations depending on your device:
   • 5th to 8th Generation Devices – “Settings” > “Security” > “Apps from Unknown Sources“.
   • 3rd and 4th Generation Devices – “Settings” > “Applications” > “Apps From Unknown Sources“
   • First and Second Generation Devices – “Settings” > “More” > “Device” > “Allow Installation of Applications” and ensure it’s set to “On“.
2. Open the Kindle Fire web browser and download the APK file. You can also transfer APK files from your computer by connecting the Kindle Fire to the computer with a USB cable.
3. Open the notification area (top bar). It should show that the .APK file is downloading. Tap it once the download has finished.
4. Select “Install“.

FAQ

Why is the “Install” button grayed out?

Amazon released an update that does this sometimes. You can usually get around it by pressing the square button next to the circle home button. Then go back to the install screen. Doing that will light up the Install button.

Some people say that using the “Back” button instead of square then returning to the install screen works to light up the Install button.

How to install Google apps on Kindle Fire HD or HDX

Here's how to install Google apps on Kindle Fire HD with no rooting required

One of the main reasons to root your Kindle Fire is so you can install the Google Play Store and have access to apps that can't be found in the Amazon Appstore. But if you're worried about voiding the warranty or dealing with the rooting process in general, you can sideload apps. The cool thing about this technique is it doesn't require you to root the device first. Here's how to get most of the Google apps on your Kindle Fire HD or HDX.

For this article I'm using the latest 7-inch Kindle Fire HDX, which runs Amazon's customized version of Android 4.2. This should work the same on the 8.9-inch version too. Keep in mind that when sideloading these apps, not all of the features will work correctly. For instance, on the Google Search app, the Google Now cards don't load like they would on a Nexus 7 or other Android device. All of the APK (the Android application format) files offered here are free, malware free, and free to distribute.

What is sideloading and how do I do it?

Sideloading is the term used to describe installing an app on your Android device from a source other than an official app store. Basically, what you're doing is transferring an APK file from your computer to your tablet or smartphone and installing it directly. Since the Kindle Fire runs a forked version of Android, this is a common practice to get the apps you like on the device.

Before you can sideload an app on the Kindle Fire HD or HDX, you need to enable the feature that allows you to install apps from unknown sources. To do that, go to Settings > Applications and make sure "Apps from Unknown Sources" is turned on.

Next, download this zip file and extract its contents to a convenient location on your computer. The zip file includes the four essential apps you need to install first.

Connect your Kindle Fire to your computer using the included micro-USB cable and transfer the four APKs you just downloaded to your Kindle's Download folder.

Make sure you have ES File Explorer on your Kindle Fire. It's free and available in Amazon's Appstore. This will give you access to the APKs you transfer to your tablet. You'll find the files in Local > Home > Download.

Now perform the following steps in order:

1. Tap to install Google Account Manager and reboot the tablet.
2. Tap to install Google Services Framework and reboot the tablet.
3. Tap to install Google Play Services and reboot the tablet.
4. Tap to install Gmail and reboot the tablet.

Installing Google apps

After those four apps are installed, open the Gmail app (you'll find it listed under the Apps section on the Kindle Fire) and sign in with your Google account. After signing in at the screen shown below, you'll be kicked to the web version of Google to sign in again.

When you're signing in, you'll see various messages about different Google services stopping. You can just tap through them. This is one of the caveats with sideloading Google apps and running them – the apps will still work, it's just kind of annoying having the occasional alert pop up like the one in the screenshot below.

Once you're signed in, you'll be able to run the Gmail app on your Kindle Fire. Here's an example of it running on my Kindle Fire HDX.

Now you can continue to sideload the Google apps you want to use following the same process as above. Transfer them to the Download folder on the Kindle Fire, just like you did with the first set of apps.

Open ES File Explorer, open the Download folder, and tap to install the Google apps you want. For best results, I recommend installing one app at a time and rebooting after each one.

Just click on the following apps to download the APK file and sideload it on the Kindle Fire. In my tests, each of the following work with little to no bugs: Chrome, YouTube, Google Search, Google Music, Google Play Movies, Gmail, and Newsstand.

Summing up

You can find other Google app files in Android forums or an APK repository site like Android Drawer. A word of caution about sideloading apps: Ensure you're getting them from a trusted and secure source. Some apps – especially the ones that claim to give you paid apps for free – in the shady markets contain malware that will wreck you device. We don't condone sideloading paid apps, and in the end it will just get you into trouble. But as long as you're careful and download the apps from a trusted source you should be ok.

While some of the app features don't work the same as on a typical Android device, and the error messages that pop up are a bit annoying, it isn't a deal-breaker. As long as you're able to overlook those caveats and live in the Google ecosystem, sideloading the apps is something you should definitely try.

Install Packages with Homebrew for OS X

Homebrew is the most popular package manager for Mac OS X. Homebrew Cask extends Homebrew with support for quickly installing Mac applications like Google Chrome, VLC, and more. No more dragging and dropping applications!

This is an easy way to install Mac terminal utilities and graphical apps. It’s a bit like Chocolatey or OneGet on Windows, or the package managers included with Linux. It’s even a way to install many of the useful apps that aren’t in the Mac App Store.

The Basics

Homebrew is a package manager designed for installing UNIX tools and other open-source applications on Mac OS X. It will quickly download and install them, compiling them from source. Homebrew Cask extends Homebrew with support for installing binary apps — the kind you normally drag to your Applications folder from DMG files.

Install Homebrew and Homebrew Cask

First, you’ll need the command-line tools for Xcode installed. On a modern Mac OS X system, you can install these just by running the following command in a Terminal window. You could also install the full Xcode application from Apple, if you prefer — but that takes up more space on your Mac and isn’t necessary.

xcode-select --install

Next, install Homebrew. You can just open a Terminal window, copy-paste the following command, and press Enter:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

This script informs you what it will do. Press Enter and then provide your password to install it. By default, it installs Homebrew so you can use the brew command without typing the sudo command and providing your password.

Run the following command once you’re done to ensure Homebrew is installed and working properly:

brew doctor

Once you’re done, run the following command to install Homebrew Cask. It uses Homebrew to install Cask:

brew install caskroom/cask/brew-cask

Install Graphical Apps With Homebrew Cask

Now you can get started installing those graphical apps you want. This involves some very simple commands. To search for one, use the following command:

brew cask search name

To install an app, run the following command. Homebrew Cask will automatically download it, extract the app, and install it to your Applications folder.

brew cask install name

To uninstall an app with Homebrew Cask, run the following command:

brew cask uninstall name

Install Open-source Utilities With Homebrew

The Homebrew command is the underlying package manager that installs all those UNIX and open-source utilities you might want. It’s the easiest way to install them on Mac OS X, just as it is on Linux. Like Homebrew Cask, it uses simple commands.

To search for a utility:

brew search name

To download and install that package:

brew install name

To remove that package from your system later:

brew remove name

For more details on using these commands, read the Homebrew Cask Usage guide or the Homebrew brew command manual on their official websites. Not every graphical application or Unix utility you’re looking for will be available, but most of them probably will be.

---

Unfortunately, there’s no graphical user interface for Homebrew Cask. This is a shame, because — while we geeks love easy terminal utilities — many people could benefit from easy software installation on Mac OS X. They can avoid all the downloading DMG files and clicking around. And, since Mac OS X is now home to Windows-style installer crapware, Homebrew Cask is a way around that.

UPDATE IONIC-CLI AND CORDOVA - ionic2

The first thing you probably want to do is make sure Ionic-CLI and Cordova are up to date:

 

1	npm install -g cordova ionic@beta

 

This line will also install both frameworks from scratch if you don’t have previous installations.

 

For the next step, you need to be inside a project folder.

UPDATE IONIC 2 PROJECT

 

Warning: Backup your project before you do this next step.

 

I bet a lot of you have a previous experience with Ionic v1. Back then, Ionic v1 was updated using this line:

 

1	ionic lib update

 

This solution no longer works. Ionic v1 used bower under the hood; Ionic v2 is moving away from this approach.

 

New solution requires us to know current Ionic v2 version. To find this information, open an official Ionic Framework npm page, look at the right side, you’ll find it there:

 

 

This value should be a current Ionic 2 Framework version.

 

Let’s get back to our local project. Find a local version of package.json, search for a dependencies section, and update ionic-framework parameter value.

 

If Ionic 2 is still in alpha status, prior to doing next step, you may want to remove the ionic-framework folder from node_modules folder.

 

Update your project using this line:

 

1	npm install

 

 

While manually updating Ionic 2 settings, you can’t know if a newly updated version also requires additional/new dependencies. If any dependency changed since the last installation, you’d receive an error looking like this:

 

1 2 3 4 5 6 7 8 9 10 11

npm ERR! Windows_NT 10.0.10586 npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "install" npm ERR! node v4.2.3 npm ERR! npm  v2.14.7 npm ERR! code EPEERINVALID   npm ERR! peerinvalid The package angular2@2.0.0-alpha.52 does not satisfy its siblings' peerDependencies requirements! npm ERR! peerinvalid Peer ionic-framework@2.0.0-alpha.49 wants angular2@2.0.0-beta.0   npm ERR! Please include the following file with any support request: npm ERR!     E:\Programiranje\Ionic2\Ionic2FirstApp\npm-debug.log

 

As you can see, my current Ionic 2 version requires newer Angular2 version; update package.json accordingly.

 

Do this step over and over until you find a stable combination.

 

Finally, let’s check if everything is working as it should:

 

1	ionic serve
