Error during compiling

[teicors]

Hi, until yesterday I was able to compile my little project, but today I'm getting this error:

Creating SPIFFS image 'out/Esp8266/debug/firmware/spiff_rom.bin' Traceback (most recent call last): File "/opt/sming/Sming/Libraries/Spiffs/spiffsgen.py", line 566, in main() File "/opt/sming/Sming/Libraries/Spiffs/spiffsgen.py", line 542, in main raise RuntimeError('given base directory %s does not exist' % args.base_dir) RuntimeError: given base directory files does not exist

I tried make with clean, dist-clean, submodules-clean, components-clean but no luck at all: can someone can give me the direction to solve my issue?

BR, Angelo
