can't compile nor write with the esp8266 sketch data upload..

[staffa007]

I literally tried everything... on a mac, on windows, on arduino 1.8.10 down to 1.6.7...python 2.7.15,
ajson 5 and ajson6 , i've installed all the libraries that were popping out as missing...
I can't get it to work
This is the error with the tool "esptool write_flash: error: argument

: Must be pairs of an address and the binary filename to write there

SPIFFS Upload failed!"

This when compiling:"

I'm literally out of ideas and it's a pitty 'cause it is the most complete manager as far as I'm concerned...
