Node fs Error: EPERM: operation not permitted, open
On my Windows 10 machine, I encountered this error when running an old Node JS project. I think Node version 10.16.
In any case, it was trying to modify a dotfile in my project. Be sure that the file isn't hidden on Windows. After unchecking the hidden option in the file properties pop up. Everything worked.
So to fix:
Right click file in Windows Explorer
Select properties
Uncheck Hidden
Click Ok
Re-run your command.
