Steps to reproduce error
npm i @nut-tree/nut-js

Hi @kokarn 👋

To be honest, this looks odd.
nut.js 2.0.0 no longer depends on opencv4nodejs-prebuilt, so I'm wondering how it ends up in your build?

[kokarn]

Hello!

So it seems I might have posted in the wrong place (ish).
It's template matcher that installs it and I was running in a non-empty directory.

However, the exact same error is thrown with npm i @nut-tree/template-matcher

[s1hofmann]

Looks like the npm config setting is not properly picked up with npm 8.x.x.

Can you try to manually set the right config via environment variable: npm_package_config_opencv=4.1.1-7?

[kokarn]

Nice find! That worked!

Probably also solves #328 if fixed 👍

I might have spoken too soon. Tried installing in another project that actually uses it and it results in this

Did some more digging for you. Not sure what's up with my system really :D
npm 7 fails in the same way 8 does.
npm 6 succeeds with installation but tries to build (even tho I don't think it should?) and fails to build because I don't have python which makes half-sense I guess?

Installing python now to see what that will result in

Hate to break it, but seems even stranger when I manage to build myself.
It builds, add the file to the correct path (C:\Users\nuc\Documents\GitHub\nut-project\node_modules\opencv4nodejs-prebuilt\build\Release\opencv4nodejs.node) and then fails to load it?

[s1hofmann]

Could you please start a fresh and empty npm project on node 16.13.1 and run

npm i @nut-tree/nut-js
npm i @nut-tree/template-matcher

and tell me the output?

Because:

• You shouldn't even have rebuild anything, since @nut-tree/template-matcher ships a pre-compile OpenCV binding compatible with node 16.
• At this point I lost track of your changes and I only want to focus on nut.js et. al. without any additional packages
• Did you check https://nutjs.dev/docs/tutorial-first_steps/prerequisits#windows or https://github.com/nut-tree/nut.js#windows?

[kokarn]

I will give you that output ASAP, but here's a summary to help out

npm 7 & npm 8

• Install fails on npm 7 & npm 8 by default
• Install succeeds on npm 7 & npm 8 with npm_package_config_opencv=4.1.1-7 but the package isn't actually installed.
  • Doing a simple require leads to MODULE_NOT_FOUND

npm 6

• Install tries to build.
  • No matter if the build itself succeeds or fails the install command returns success.
  • Even if the build succeeds it fails to load even with a simple require resulting in ERR_DLOPEN_FAILED

EDIT: Also, yes I have installed the Microsoft Visual C++ Redistributable :)

And you have met the prerequisites?

Because I can't reproduce this issue and a missing runtime could cause this problem.

The prereq is only the Microsoft Visual C++ Redistributable, correct? If so then yes. Does it matter which windows version it is perhaps?

EDIT: To clarify

[kokarn]

Your clue of "prerequisites" solved it for me. Another repository I have run had other weird issues on my windowses, the N version. The reason is that they are missing the "Media Feature Pack".

As that was also OpenCv I tried it out, and it works. It's the Media Feature Pack which is missing both on some N versions and other more streamlined versions of Windows.

The type initializer for 'OpenCvSharp.NativeMethods' threw an exception.
This probably means you are missing the Windows Media Features.

There are two ways to install the Media Feature Pack:

* Navigate to Settings > Apps > Apps and features > Optional features > Add a feature, and then locate Media Feature Pack in the list of available optional features.
* Download the pack installer for your Windows version from here and run it.
  * After the installation has finished, restart your computer to make sure the changes are applied.

Installing that feature solves the install & run issues 👍
