Error While flashing code

[joe_boron]

When I try to compile and flash any code to my Particle Boron, it gives this error:

Cannot find module 'core-js/library/fn/object/assign'
Require stack:

This is very new; it was working before but not now. I am using Particle Workbench on Windows 10. I also reinstalled the extension, and that changed nothing. I am at a complete loss. Please help!

So I ran this command and it worked for me (I was able to compile and flash code to the boron on Workbench successfully):

particle update-cli

For others that come across this issue you can try the same or if yours didn't work, you can view this site.

I also re-installed Particle Workbench from this guide.

Hope this helps!!
