I explicitly set the OPENCV4NODEJS_DISABLE_AUTOBUILD=1

I've installed opencv4nodejs through brew install v3.4.14
and then run npm -g install opencv4nodejs
installation was successful

when I run appium-doctor

It shows that appium sees opencv library
it's strange that it shows that 5.6.0 version installed

When I'm trying to run test following error appears: Unable to load package 'opencv4nodejs': Cannot find module '/usr/local/lib/node_modules/opencv4nodejs/build/Release/opencv4nodejs'

but actual location: /usr/local/lib/node_modules/opencv4nodejs/build/Release/obj.target/opencv4nodejs
tried to remove obj.target folder it didn’t help

With OpenCV-contrib? (extra modules): no
Appium v 1.21.0
MacOSX Big Sur 11.4

I too have the same issue with windows, any advice would greatly helpful.

I can confirm nodecv4nodejs is installed
C:\Program Files\nodejs\node_modules>npm list -g opencv4nodejs

`-- opencv4nodejs@5.6.0

but using with appium throws - Failed to load local package 'opencv4nodejs': Cannot find module 'opencv4nodejs'

i am having the above issue also, I am on a mac with intel chip.

I believe this is most likely a versioning issue, there seems to a difference in the file structure that's called for and the one supplied by this version. i would guess slowly testing older and older versions would be a good place to start, ill post my results as soon as a find them. Cheers and good luck

[rrudiuk-devx]

After reading similar issues threads, it seems like this is an opencv4nodejs installation issue. Has anyone found a solution?

[Hacklone]

Having the same issue with Raspberry OS.

The same problem -> http://joxi.ru/8AnDXEWHNxWD1m

In your screenshot, I can see the @u4 version.

the u4 version requires you to call the build script build-opencv

that may change since my warning message may not be seen.

having same issue and fixed it !!
I've add below line to my zshrc and it works !

export NODE_PATH="/opt/homebrew/lib/node_modules"
