@ahmadasadi while you do install raspi-io as a the pi user, you have to actually run it as the root user: https://github.com/nebrius/raspi-io#system-requirements

nebrius commented 6 years ago

I'm admittedly not very familiar with node-red. Where is your node-red project stored at?

Looking at the error message, these lines pop out at me:

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

This tells me that you tried to run npm install johnny-five raspi-io from /home/pi, but your project code is located somewhere else. The npm command needs to be run from the root fo your project folder, where the package.json file is located. From this error code, it's implied to me that it's somewhere other than /home/pi.

ahmadasadi commented 6 years ago

sorry i think these lines means that raspi-io has been installed. am i right?

ahmadasadi commented 6 years ago

package.json is in pi@raspberrypi:~/.node-red and i run npm command as a root user in the following and the result is these lines: pi@raspberrypi:~ $ cd .node-red pi@raspberrypi:~/.node-red $ ls flows_raspberrypi_cred.json package.json settings.js.bak flows_raspberrypi.json package-lock.json settings.js.save lib projects node_modules settings.js pi@raspberrypi:~/.node-red $ sudo npm install johnny-five raspi-io

and above lines results frequently and non stopping

what can i do next ? thanks a lot

nebrius commented 6 years ago

Hmm, for some reason that folder is owned by a different user. Can you try running:

sudo chmod -R 775  /home/pi/.node-red/

i did it but problem not solved thanks for your help

ahmadasadi commented 6 years ago

hi my raspbian version is :+1: pi@raspberrypi:~ $ lsb_release -a No LSB modules are available. Distributor ID: Raspbian Description: Raspbian GNU/Linux 9.3 (stretch) Release: 9.3 is it ok for installing johnny-five and raspi-io?

fivdi commented 6 years ago

Yes, Raspbian Stretch is ok for Johnny-Five and Raspi-IO.

The output posted above shows the following error:

13 Feb 09:47:15 - [warn] [serialport] Error: Module version mismatch. Expected 48, got 14.

This means that Node.js v0.11 or v0.12 is being used at runtime but Node.js v6 is expected.

The Node.js module version numbers for the different versions of Node.js can be found at https://nodejs.org/en/download/releases/

Raspi-IO itself requires Node.js v4.0.0 or higher.

It looks like the Raspberry Pi is not configured correctly. Perhaps the users root and pi are accessing different versions of Node.js.

What's the output of the following two commands?

node -v
sudo node -v
ahmadasadi commented 6 years ago

hi thanks a lot answer is :+1: pi@raspberrypi:~ $ node -v v6.12.3 pi@raspberrypi:~ $ sudo node -v [sudo] password for pi: v6.12.3

ahmadasadi commented 6 years ago

sorry the thumb sign came by mistake excuse me i mean answer is :

fivdi commented 6 years ago

Hmm, I don't understand what's happening yet.

What's the output of the the following commands?

nodejs -v
sudo nodejs -v
nebrius commented 6 years ago

There's definitely some sort of Node.js version mismatch at play, but what I can't say specifically. From the output of node -v and sudo node -v it looks like pathing is set up correctly there. @monteslu do you know if node-red ships its own Node.js runtime?

Another thing I see: you shouldn't use sudo with npm install. Instead, you should run npm install johnny-five raspi-io without the sudo part. Can you try without sudo and see if that helps?
