npm installing opencv failed

[RGDEV2022]

Hi, I know this topic has been discussed everywhere but I cannot get anything to work and I really need some help.

Windows 10
npm 5.4.2

I am trying to get https://github.com/paulhayes/copterface to work for my Ar-Drone

Followed the steps
npm install ar-drone
npm install opencv

No luck what so ever, pre built binaries not found for [email protected] and a whole lot of other errors.

Is there a guide to make this work? I've read a hundred forums here and elsewhere regarding this but it's impossible to make work since the information on this topic is so scattered.

ERROR

Any help would be greatly appreciated.

I have the same. What suggestions? Anyway will be doing research.
I recently fixed OpenCV issue for CentOS (ageitgey/face_recognition#191 (comment)), and I will try to research this NodeJS issue - maybe it's the same issue, maybe I need to install Visual Studio.

PS. @rojig this ur issue seems to be duplicated of #12 - I would recommend delete/close ur issue.

Is anyone here who fixed it? I got the same issue.

[RGDEV2022]

Yes, there was a calibration issue. You need to press the C button to calibrate the sensors before flying.
