Platformio-ide not found, unable to build, NoneType error

[bryce-g]

Issue:

Can't build or pio run
command 'platformio-ide.serialMonitor' not found
This works on my other win10 PCs and has previously worked on this PC. I've already tried a few different python versions and uninstalling and reinstalling everything.

It build

If problems with PlatformIO Build System:

This might be related to #4828.

I ran into the same issue where PIO threw a TypeError: argument of type 'NoneType' is not iterable exception when parsing my platformio.ini file, and reported it was invalid.

I switched to the dev branch like the attached issue (run pio upgrade --dev), and using the dev branch fixed it for me.

Thank you so much, yes that fixed it.
