Error: Cannot find module 'bonescript'

[Maurice H.]

I have this simple script that I want to execute at boot time.

The script:

root@bbone:~# cat boneboot/ledsoff.js
var b=require('bonescript');


b.pinMode('USR0', 'out');
b.pinMode('USR1', 'out');
b.pinMode('USR2', 'out');
b.pinMode('USR3', 'out');


b.digitalWrite('USR0', 0);
b.digitalWrite('USR1', 0);
b.digitalWrite('USR2', 0);
b.digitalWrite('USR3', 0);

To run it at boot I've created a file in /etc/cron.d which looks like this:

root@bbone:~# cat /etc/cron.d/boneboot
# m h dom mon dow user  command
@reboot   root    sleep 120 && /usr/bin/nodejs /root/boneboot/ledsoff.js 2>&1 | logger -p info -t ledsoff

Unfortunately, when I reboot the BBB the code is not executed succesfully as shown by the log:

However, when I logged in as root, the code executes normally.

Any suggestions on how to proceed?

I've solved this by adding a line to the cron job that sets the environment variable NODE_PATH.

NODE_PATH=/usr/local/lib/node_modules

# m h dom mon dow user  command
@reboot   root    sleep 120 && /usr/bin/nodejs /root/boneboot/ledsoff.js 2>&1 | logger -p info -t ledsoff
