This error appears when starting PIO, however after dismissing it I can still seem to browse the PIO menus just fine.
System info:
Could you try manually create virtual environment for PIo Core? http://docs.platformio.org/en/latest/installation.html#virtual-environment
I tried it just now (removed existing penv directory and followed the rest of the steps), same error message.
Could you try this solution? http://docs.platformio.org/en/latest/faq.html#importerror-cannot-import-name-remove-dead-weakref
That worked, problem solved!
