I am trying to use opencv for nodejs for my image processing. I’m slightly familiar with it’s Python version, but it seems like it also exists in Javascript. When trying to install it, I keep running in errors. The most common one is this:

I found that others also have a similar issue, but I have tried many things (added opencv to my system variables for starters), reinstalled everything, but still.. I keep getting this error 🙁
Any help is welcome! 🙂 I thank you in advance. I am using https://www.npmjs.com/package/opencv4nodejs#how-to-install
