Hi All

Does anyone have a step by step install to get this working?

I’ve tried all using



and I still get the
root@raspberrypi:/home/pi/blynk-library/linux# sudo NODE_PATH=/usr/local/lib/node_modules/blynk-library node ./blynk.temp.js
module.js:338
throw err;
^

Look like something wrong with paths to libraries. @vshymanskyy maybe you can help?

Please try:

sudo NODE_PATH=/usr/local/lib/node_modules/ node ./blynk.temp.js

@Dema323 this thread is more than a year old but I guess your fix is the same as it was back then.

Find the correct path for the blynk-library module.

Yes, no need to extract or so just need to put the full path to the library otherwise he doesn’t find it.
