Unable to install: `library dir does not exist`

Description

I am trying to use opencv4nodejs to capture my webcam, but I am not able to install it. I tried a lot of other things and other ways to install opencv4nodejs, but none were successful, so I will just post the result of an auto build.

Error Message

Error: library dir does not exist: D:/projects/webcam/node_modules/opencv-build/opencv/build/lib/Release

I have the same problems.

Experiencing the same issue on MacOS using node version 16.13.1.

[UrielCh]

Please try that : in am admin power shell

choco install cmake -y

in you user cmd / powershell

cd D:\projects\webcam
npm i -g node-gyp
npm i @u4/opencv4nodejs
echo build nodejs
node .\node_modules\.bin\build-opencv --help
node .\node_modules\.bin\build-opencv --version 4.5.4 build

The errors messages of this version are way cleaner, and the build should works fine with nodeJS 16

PS: do not use 4.5.5 on MacOS. PS: the original version do not work with Visual Studio 2019.

In my situation, the root cause is that it cannot auto build (or even install) the opencv-build package.

When I try to install opencv-build by executing npm i opencv-build, it stucked on reify:... Completed in XXXms, then I found this thread.

After downgrade npm by npm i -g npm@6, then try again, everything works like a charm.

I was having issues with this as well. Downgrading to Node 14 worked for me.

Thanks for the information, I also faced the same issue, and it worked after downgrading the npm version to 6

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.

• Windows:

choco install opencv

• Mac:

brew install opencv

• debian:

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

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)
