private-registries-install-scripts-runner

This helper is a way to workaround [BUG] Regression: custom scripts not executed on dependencies from custom registry · Issue #4821 · npm/cli.

Being published on official npm registry, this helper install script is run by npm in most version (at least 6+), and can then start install scripts from libs on custom/private registries, which is broken since npm 7.

To use simply add dependency to this helper: npm i --save private-registries-install-scripts-runner
