Still tries to build OpenCV even when already installed by chocolately on Windows

[liftyourgame]

Have installed OpenCV on Windows by Chocolately in PowerShell:

choco install OpenCV -y -version 4.1.0

Set environment variable system wide:
OPENCV4NODEJS_DISABLE_AUTOBUILD=1

Install @u4/opencv4nodejs

npm install @u4/opencv4nodejs

Get this in the logs: and can't see node-gyp rebuild is running

That's not the first time I saw this kind of error, do you have an anti-virus running on your system that may cause errors during the cleaning step? Try to disable the antivirus live protect and check if you have the same issue.

[liftyourgame]

Thanks. Disabled Malwarebytes but still get the error. I don't think deleting is the problem is it? Why is it trying to build OpenCV when the OPENCV4NODEJS_DISABLE_AUTOBUILD flag is set to 1?

[studentutu]

same here, fixed it by using pnpm - somehow default npm tries to build lib even when all conditions to disable autobuild are met.

[liftyourgame]

Did:

choco install pnpm
pnpm install

Still get the same result.

[studentutu]

try to clean all npm caches and such, and also remove ./node-modules - and strictly use pnpm - it will use symlinked folders in your ./node-module, this is probably why it works with pnpm
Also install globally nody-gyp or something like this ( see the package for opencv4nodejs), as it is one of the requirements for build project

[liftyourgame]

So did:

npm cache clean --force
del node_modules
pnpm install -g node-gyp

pnpm install

Get the same result

[liftyourgame]

Ran:

Remove-Item .\node_modules\

$env:OPENCV4NODEJS_DISABLE_AUTOBUILD=1
$env:OPENCV_INCLUDE_DIR='C:\\tools\\opencv\\build\\include'
$env:OPENCV_LIB_DIR='C:\tools\opencv\build\x64\vc15\lib'
$env:OPENCV_BIN_DIR='C:\tools\opencv\build\x64\vc15\bin'

pnpm i

Still get:

node_modules/.pnpm/@[email protected][email protected]/node_modules/@u4/opencv4nodejs: Running install script, failed in 1m 41.1s
.../node_modules/@u4/opencv4nodejs install$ node-gyp rebuild

Why is node-gyp rebuild running?

Seems to be starting around line 319 of compileLib.js

[tothadi]

Same here since version 7.0.0. I have a custom docker image with prebuild opencv but npm ci still tries to build everytime and gyp fails every time.

[meesii]

same issues

[UrielCh]

I have have a windows PC, let me try that....

any command line sequence to reproduce the issue ?

[meesii]

@UrielCh
Yes, I set all the system environment variables, and then executed "npm i @u4-opencv4nodejs" and the above problem occurred.

Including setting "disableAutoBuild" in package.json, "OPENCV_INCLUDE_DIR", "OPENCV_LIB_DIR", "OPENCV_BIN_DIR" are also invalid.

I just installed Visual Studio 2022, and "npm i @u4-opencv4nodejs" was successful, but when running it, it still prompted me to install opencv.

Then I installed "@u4-opencv-build" and executed "npx build-opencv --version 4.6.0 rebuild", which also prompted me with errors related to "node-gyp".

[UrielCh]

4.1.0 ??

that may be the issue, the current version is around 4.10.0, 4.1.0 is very old

[UrielCh]

oups, you do not need the build-opencv anymore...
I improve that some version ago, now I use the default build process.

just use npm install @u4/opencv4nodejs once our environement variables are set or, after adding the extra parameters in package.json.

but the tatest version do not need any parameter, and will by default locate you choco openCV version and use it out of the box.
