[BUG] On RaspPi 3, nodejs, simply require opencv crash

[pedefe]

Hello,

on RapsPi 3 I follow the following steps: ¤ apt-get install libopencv-dev In my nodejs project (already moving a standalone robot with servos, etc...), ¤ npm install opencv Then I just require "opencv" in my test_opencv.js file : ¤ var cv = require("opencv"); Then I execute: ¤ node test_opencv.js Then : root@raspberrypiNEXO-01:~/nodejs/AutoMove# node test_opencv.js internal/modules/cjs/loader.js:807 return process.dlopen(module, path.toNamespacedPath(filename)); ^

Error: libopencv_videostab.so.3.4: cannot open shared object file: No such file or directory at Object.Module._extensions..node (internal/modules/cjs/loader.js:807:18) at Module.load (internal/modules/cjs/loader.js:653:32) at tryModuleLoad (internal/modules/cjs/loader.js:593:12) at Function.Module._load (internal/modules/cjs/loader.js:585:3) at Module.require (internal/modules/cjs/loader.js:692:17) at require (internal/modules/cjs/helpers.js:25:18) at Object.

Best regards.

Found a solution... ¤ find where is opencv libraries listed in debug-log: ... find / -name "libopencv_core.so.3.4*" ... /root/nodejs/AutoMove/node_modules/opencv-build/opencv/build/lib/libopencv_core.so.3.4

¤ In /etc/ld.so.conf.d folder, create text file "opencv.conf" ... write found-path in it, i.e. "/root/nodejs/AutoMove/node_modules/opencv-build/opencv/build/lib"

¤ Execute : ldconfig -v | grep opencv > verify that "opencv" items are listed.

¤ Then nodejs program runs without error.
