RE: Making uEnv.txt Suit My Needs and Running Software/How Do I Put 'bonescript' in My Path...

[Mala Dies]

Hello,

As many of us already know, I am working with the TMP36 and failing harder than ever for some reason on my BBB. I just noticed my error code for the software. It is stating that the BBB cannot find the 'bonescript' language that I am invoking. 

Seth

P.S. How can I put the 'bonescript' language in my PATH so when I run the .js file, 'bonescript' is "noticed" and can be used? I am working directly in the /home/debian directory. Send guidance or assistance, i.e. either/or.

Cut & paste the exact error message (along with the command line being
used to invoke the program).

Bonescript is not a "language" per se, so much as an import
library/module for node.js which activates access to the BBB hardware. It
corresponds to the Python BBIO (various over the years) library.

If the bonescript module is not being found by node.js, that is one
thing, and changing your normal PATH variable probably won't help -- PATH
tells the OS where to look for executable programs; where those programs
look for import libraries is a different matter. If node.js is not being
found, then your PATH is likely really trashed, since it should be in one
of the standard directories (/bin, /usr/bin, etc.)

root@ELUSIVEUNICORN:~# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

(the above is from Windows 10 "BASH on Ubuntu on Windows" add-in, Debian
should be similar)


Seeing the exact error message would help identify the type of problem
you have.

Unfortunately I can't help with node.js -- the whole way of programming
in it just doesn't fit my mindset. A problem with Python would be more in
my realm.

Hello,

Here is the error message when I use sudo node tryTemp.js to run the .js file on my BBB in PuTTY. 

module.js:491

    throw err;

    ^

Error: Cannot find module 'bonescript'

    at Function.Module._resolveFilename (module.js:489:15)

    at Function.Module._load (module.js:439:25)

    at Module.require (module.js:517:17)

    at require (internal/module.js:11:18)

    at tryModuleLoad (module.js:470:12)

    at Function.Module._load (module.js:462:3)

Oh and sir, the software I am using to invoke 'bonescript' is:

var b = require('bonescript');

function readTemp() {

    b.analogRead('P9_40', displayTemp);

}

function displayTemp(reading) {

    var millivolts = reading.value * 1800;

    var Celsius = (millivolts - 500) / 10;

    var Fahrenheit = (Celsius * 9/5) + 32

    console.log("Celsius=" + Celsius + "/tFahrenheit=" + Fahrenheit;

}

setInterval(readTemp, 8000);

Seth

P.S. Thank you for any support.

Hmmm, I thought more recent OS had renamed "node" to "nodejs" due to a
conflict with an amateur radio packet program.

Not a PATH error itself -- PATH found node.js (by whatever name).

I'd have to study node.js documentation to find the answer (but since I
peaked ahead, I won't bother -- I'll just save that answer to my own
archive for future)

Hello Sir,

I tried this out. I used that BASH command and it did not locate my node_modules under /usr/local/lib for some reason. I have the 2 GB version: Linux beaglebone 4.9.37-ti-r47 #1 SMP PREEMPT Thu Jul 13 22:48:49 UTC 2017 armv7l GNU/Linux. Should I update to the latest release of Stretch?

Seth

P.S. I do not even have node on my system right now for some reason. Oh and I do not have bonescript located anywhere on my machine either. This is the issue since I am using an invocation of 'bonescript' via var b = require('bonescript'); in a .js file.
