How to install node.js with GPIO

Question

I am trying to install node.js on my Raspberry Pi as well as GPIO.

I am running a brand new install of Debian Jessie

I could get nodejs v.0.10.29 installed. No matter what I do, this is pretty much the most recent package I have been able to install even if a lot of post I read are speaking of version 4.0.0.

However v0.10.29 is running and I could run a simple http server.

The problem comes when I try to install GPIO. I have tried the following;

• rpi-gpio
• pi-gpio
• onoff

I can't get any of them to work and I have played around trying anything I could find on the web to fix it. I have tried pretty much everything.

So, since I probably messed up a lot of things, I reinstalled the OS Debian {Ed: Raspbian} Jessie and will give it another shot.

From there, what should I do after my OS is installed to get this to work?

Anyone have a good set of instruction for this - because I am probably missing something, right?

If anyone is willing to help I would gladly follow instructions and post any error messages I'm getting, because so far this is all I have been getting.

So I guess I will start with:

sudo apt-get update

What's next?

EDIT #1 Nodejs v0.10.29 is installed

I have installed Nodejs as suggested by Joan:

wget https://nodejs.org/dist/v4.3.1/node-v4.3.1-linux-armv6l.tar.xz
tar xf node-v4.3.1-linux-armv6l.tar.xz  
cd node-v4.3.1-linux-armv6l/ 
sudo cp -R * /usr/local

nodejs -v 

returned;

v0.10.29

EDIT#2 pi-gpio install

Now that node is installed I have try to turn a led on on pin 18 and got the following error;

module.js:340 
throw err; 
^ 
Error: Cannot find module 'pi-gpio' 
at Function.Module._resolveFilename (module.js:338:15) 
at Function.Module._load (module.js:280:25)

at Module.load (module.js:356:32) 
at Function.Module._load (module.js:312:12) 
at Function.Module.runMain (module.js:497:10)

So I have installed pi-gpio using npm;

sudo npm install pi-gpio

I am now getting this error;

Error when trying to open pin 18
/bin/sh: 1: gpio-admin: not found

Error when trying to close pin 18
/bin/sh: 1: gpio-admin: not found

So I will now install gpio-admin.

And this where it get messy because gpio-admin is old and wont install on the Debian Jessie So if anyone can come up with a way to turn on a led from Nodejs under Debian Jessie that would be awesome.

Answer 1

For example to install RPi nodejs version 4.3.1 (see below for other versions)

wget https://nodejs.org/dist/v4.3.1/node-v4.3.1-linux-armv6l.tar.xz
tar xf node-v4.3.1-linux-armv6l.tar.xz  
cd node-v4.3.1-linux-armv6l/ 
sudo cp -R * /usr/local

Check installation with

node -v

Different versions are available from https://nodejs.org/dist/

For the Pi2B make sure you download a linux-arm7l build, for all other Pis make sure you download a linux-arm6l build.

Answer 2

Figured out how to get *GPIO* working with *Nodejs*.

Let me tell you that this was far from being Plug and play.

**OS** : *Raspbian Jessie*

**Nodejs**: *Version 4.3.1* ( Credit to joan)

Note that you should remove any old installation of *Nodejs*.

I have updated *npm* with the following command;

sudo npm install -g npm@latest

Then I have installed *gpio v0.2.7*;

 sudo npm install gpio

and got the folowing warning;

npm WARN enoent ENOENT: no such file or directory, open '/home/pi/package.json'

So I will have to deal with that.

Then I have installed *rpi-gpio*;

sudo npm install rpi-gpio

Still got the warning about package.json. At this point my script was working I could reach the server and my led light came on.

Other install I have made due to warning and errors:

sudo npm install graceful-fs@^4.0.0
sudo npm install node-gyp

I'm not sure that the last 2 installs where needed but it ended up working so you might want to try that to.
