Yes. Antivirus is active. It coud be the problem … hmm … I have the same issue with node.js edge-impuls… I cant’t install it - some folders are missing (they are created and then … immediately disappeare).
pio run -j1 -v
‘pio’ is not recognized as an internal or external command,
operable program or batch file.
It might be the compiler but then it’s super weird how you’ve gotten a compiler warning in the above compile log above. You can try and delete the C:\Users\<user>\.platformio\packages\toolchain-gccarmnoneeabi and C:\Users\<user>\.platformio\.cache folders to force a redownload of the toolchain.
Otherwise I’d suggest to temporarily disable antivirus to check if that’s the fault.
I spend many hours finding the solution and unfortunately nothing works for me … I can’t use PatformIO …
Decided do uninstall it and install again … and trace installation … is it normal? Red exceptions?!
