Hi I'm trying to use opencv in my Node.js project so I decided to use opencv4nodejs
. I tried to install this module by npm
and i discovered some errors related to absence of cmake
on my computer. So I decided to install cmake
by brew
. But after this process when I'm trying to install this module the following errors occurs:
MacBook-Air-Micha:webcam-myidea michalkukielka$ npm install opencv4nodejs

Please check your CMake and compiler installation. If you are cross-compiling then ensure that your CMake toolchain file correctly sets the compiler details.

As I understand there are some new problems with cmake
but I cant find solutions for.
Could you help me finish the proces of installation opencv4nodejs
?
