Question: how to create a NSWindow?

[王凯鹏]

I write a nodejs-addon to create a NSWindow,but failed to display it.Then someone told me to call [NSApp run],the window can display now,but nodejs's even loop is stopped by NSApp run.
Any idea how to fix it?

I tried to install NodObjC but failed

npm WARN deprecated NodObjC@1.0.0: The npm registry can, sadly, no longer handle package names with uppercase characters… You must use the 'nodobjc' package now.
