SOLVED macOS Installation issues. #852

Open EdoTrotta opened 2 years ago

EdoTrotta commented 2 years ago

ERROR:

Error: Cannot find module '/Users/yourName/Desktop/project2/node_modules/opencv4nodejs/build/Release/opencv4nodejs'

Follow these steps and you should be able to install and work with this library. I've spent several hours trying to solve the issue and I think I've found something that works:

  1. Install OpenCV:
  1. Inside your repository:

This process should actually trigger the build in opencv4nodejs and now the module can be used without issues.

Hi, Great news for those people that do not want to build their OpenCV: I published @u4/opencv4nodejs V 6.2.4 today,

This version autodetects the common setup path for Brew on Mac, Chocolatey on Windows, and Apt on Linux.

just define environment variable: OPENCV4NODEJS_DISABLE_AUTOBUILD=1

And your prebuild OpenCV will be used.

You may need to call: npx build-opencv rebuild or npx build-opencv --nobuild rebuild (if you do not define OPENCV4NODEJS_DISABLE_AUTOBUILD variable)

  • Windows:

choco install opencv

brew install opencv

apt -y install libopencv-contrib-dev libopencv-dev
