Hi, keep getting the following error message every time I try to create a photon app. Using R 3.5.3 and the default "old faithfull" shiny app. Both git and node.js are installed on the system.

Listening on http://127.0.0.1:5510
Running Photon
The directory is ...

Which operating system are you using? Can you send sessionInfo()?

Have the same issue here!

@R-Michael @MooJoh

I think that this should work on Windows now. Could one of you please test and let me know? I will close this issue if no problems persist.

MooJoh commented 5 years ago

Thanks @aarizvi the build process seems to run through now, thanks! However, I have no idea how to start the resulting app ? Do I need npm installed on the system which shall only run the app too? (with "npm start"?)

aarizvi commented 5 years ago

@MooJoh you should just be able to double click on the electron-quick-start executable in the \ElectronShinyAppWindows\electron-quick-start-win32-ia32 directory and a standalone chromium browser should open up.

Even if the app doesn't work the browser should still open up. Does it?

MooJoh commented 5 years ago

Unfortunately, only a white window shows up, but none of the shiny app ui elements is displayed ...

aarizvi commented 5 years ago

@MooJoh -- I believe that issue has been resolved. Try again and let us know.
