    It seems this error is caused by installing the package using "new" versions of node/npm. There are a lot of issues talking about this problem on the project’s Github repository, for example this one. Workarounds that might or might not lead to success include downgrading npm, installing a dependency of opencv4nodejs first, disabling automatic opencv.js building and installing node-gyp for building opencv.js automatically. You might want to search the Github issues for your error and read the discussions there for further information.

    However, as the project’s README states, it is no longer maintained and you probably shouldn’t use it. Instead, it recommends using this fork, which provides rather detailed installation instructions.
