Error message when running "npm install" on Raspberry Pi 2B (Jessie)

[intel66]

Error message when running "npm install" in the "server" directory:
npm WARN package.json [email protected] No README data

Yours is not an Error, just a Warning (http://stackoverflow.com/questions/18057466/npm-how-to-fix-no-readme-data) because of a missing README file. You can ignore it, just make sure that the ./node_modules dir was created without npm error log file.

NB. The package was not yet published on npm. I did it today. But watch out: we're still in Alpha. There's something that gotta be fixed and implemented yet, as you can see here: #3

Switch works great. In the next days I'll commit for the Alarm sensors too.

I've just refactor the entire directory. No more need to cd server.
Anyway you better install with npm.

npm install iot-433mhz -g --unsafe-perm

[intel66]

Hi, thanks for reply. I deleted iot-433mhz-folder and tried "npm install iot-433mhz" but got permission issues.
Tried "sudo npm install iot-433mhz --unsafe-perm"
Got endless lines of:

.......and so on.....

Ok, let's try to debug together executing this commands.

Which node.js version do you have? node -v
Are you logged in as root or pi user? whoami
Moreover your system time is correct? date

NB. I just did another upgrade 1.0.11 and updated the documentation. Now you gotta install it with the -g flag.

sudo npm install iot-433mhz -g --unsafe-perm

and then to execute:

iot-433mhz

[intel66]

Thank you for answer.
Had an old version of node, upgraded to 5.4.1, user: root, date was wrong too, now corrected. My bad..
Install went great, rebooted, but I am unable to connect via browser (192.168.2.251:8080)
when executing iot-433mhz, I must enter a port number, what port should I enter?

root@raspberrypi:~/iot-433mhz# iot-433mhz

@intel66 You must use an arduino with a 433mhz radio receiver/transmitter, connected through USB to your RPi.
As shown in this scheme: https://github.com/roccomuso/iot-433mhz#a-computer-with-arduino-connected-and-a-433-mhz-transmitter-and-receiver

The project is updated to a quite stable version (1.0.22).

sudo npm install iot-433mhz -g --unsafe-perm

remains the best way to install it on RPi.
