I believe that I began getting this error after I installed the latest -dev version of PIO Core in an attempt to resolve a previous problem. Now I get the multiple cores error whenever I build,
but I’ve been unable to resolve it by following the uninstall instruction in the FAQ:
pip uninstall platformio
WARNING: Skipping platformio as it is not installed.
I tried upgrading via PIO Terminal in VSCode:
$ pio upgrade
PlatformIO 5.1.0 is currently the newest version available.
Then I tried to PIO update, which ran successfully but didn’t affect the multiple cores (and it also reported the same issue). I also ran the PIO Core installer script:
Again, no errors, but no fix. Do I need to remove it manually by deleting this folder?
I’ve searched my hard drive, and no other .platformio folder exists, only this one: C:\Users\Matt.Barney.platformio
My environment is:
Windows 10 Pro 64-bit
PIO Core 5.1.0
PIO Home 3.3.3
PIO IDE 2.3.0
