Motivation / Use-Case

When require a [.node] file within a [.asar] package, there is an unexpected issue with the Mac system. The error message states:

Error: dlopen(/Applications/xx.app/Contents/Resources/app/application.asar//../wrapper.node, 0x0001): 
tried: '/Applications/xx.app/Contents/Resources/app/application.asar//../wrapper.node' (errno=20), 
'/System/Volumes/Preboot/Cryptexes/OS/Applications/xx.app/Contents/Resources/app/application.asar//../wrapper.node' (no such file),
'/Applications/xx.app/Contents/Resources/app/application.asar//../wrapper.node'(errno=20)

However, it can be opened when using the absolute path:
/Applications/xx.app/Contents/Resources/app/wrapper.node
To resolve this, I've used path.join to format the path.
