Problem with --buildRoot Error: No build found and Bin path not found.
OpenCV version (example 3.4.1): 4.7.0, 4.6.0 With OpenCV-contrib? (extra modules): yes OS: Windows 10 NodeJS: 18.13.0 NPM: 8.6.0
I'm using auto build, everything went fine, no error.
I use this build script
"electron-rebuild": "build-opencv --electron --version 4.7.0 --buildRoot C:/opencv build"
The build went through with no error.
But then I got the following errors when I try using OpenCV with electron (just require('@u4/opencv4nodejs')).
Error: No build found in D:\...\node_modules\@u4\opencv-build\dist you should launch opencv-build-npm once
so I try install OpenCV again without changing root. using this script.
"electron-rebuild2": "build-opencv --electron --version 4.7.0 build"
then I got another error message... saying it need v4.6.0 (but I installed 4.7.0... why?)
ERROR Error: No build of version 4.6.0 found in D:\...\node_modules\@u4\opencv-build\dist you should launch opencv-build-npm
so I try install 4.6.0 using
"electron-rebuild3": "build-opencv --electron --version 4.6.0 build"
build finished successfully, but I got another error.
main.ts:12 ERROR Error: require("[33mD:\Works\project\gee\app-new\node_modules\@u4\opencv4nodejs\build\Release\opencv4nodejs[39m");
Failed with: [31mThe specified module could not be found.
\\?\D:\Works\project\gee\app-new\node_modules\@u4\opencv4nodejs\build\Release\opencv4nodejs.node[39m, openCV module looks broken, clean you builds directory and rebuild everything
rm -r <path to your build directory>
npx build-opencv --version 4.6.0 rebuild
I try rebuild from scratch again and still getting the same error. so I try searching for a way to explicitly set opencv version for this project. I try put this in package.json
"opencv4nodejs": {
"autoBuildOpencvVersion": "4.7.0"
}
now the error changed to
ERROR Error: opencv binary dir does not exist: C:\tools\opencv\build\bin
so I try again with
"opencv4nodejs": {
"autoBuildOpencvVersion": "4.7.0",
"opencvBinDir": "./node_modules/@u4/opencv-build/dist/opencv-4.7.0-8b1ea/build/x64/vc16/bin"
}
still got the same error... but then I try changing version to 4.6.0 but 4.7.0 lib like this
"opencv4nodejs": {
"autoBuildOpencvVersion": "4.6.0",
"opencvBinDir": "./node_modules/@u4/opencv-build/dist/opencv-4.7.0-8b1ea/build/x64/vc16/bin"
}
now it working... why? why I have to put build version as 4.6.0 but bin directory as 4.7.0 ?
is there any explanation ? is there any config I needed to do but missed?
if you need the project files I can send zipped.
Here is my package.json

here is the build output
when I build electron package I got the same error as above.
Error: No build of version 4.6.0 found in C:\Users\nitip\AppData\Local\Temp\2KuuRDgr97I79JYqyv7VCI3osY8\resources\app.asar\node_modules\@u4\opencv-build\dist you should launch opencv-build-npm
what should I do ?
1st: do not use 4.7.0 use 4.6.0
2nd: define an env variable OPENCV_BUILD_ROOT=c:/opencv
3th: never use "opencvBinDir" to point a lib built by @u4/opencv-build
4th: I'm still not using electron....
Thank you for the reply. I see.
I resolved the problem at developing time by setting OPENCV_BUILD_ROOT=c:/opencv environment variable.
Is there any other way so that I didn't have to set environment variable every times I wanted to run the app?
maybe a way to specify build root in package.json? i tried buildRoot and openCVBuildRoot it didn't works.
the ERROR Error: opencv binary dir does not exist problem still occur when packaging final app. I will try to find the way.
