Start with the opencv-build install entry point, install.js, and the reported npm install command on macOS Mojave with Node 11.9.0 and npm 6.5.0. Inspect the installation output preceding the final ELIFECYCLE error to identify the underlying failure; done means the package installs successfully in the reported environment.
