Getting bunch of errors when compiling

[kxvxnk]

I am currently doing a second FastLED Project after the first time worked without problems a couple of years ago. Unfortunaly I am getting several Errors while compiling although I changed just the required setup part and nothing more. All files are untouched from the downloaded while except for the .ino file. Here are some of these errors: "In file included from c:\Users\kevin\Documents\Arduino\libraries\FastLED\src/FastLED.h:83, from C:\Users\kevin\Desktop\esp8266-fastled-iot-webserver\esp8266-fastled-iot-webserver.ino:20: c:\Users\kevin\Documents\Arduino\libraries\FastLED\src/fastspi.h:171:23: note: '#pragma message: No hardware SPI pins defined.

exit status 1

Compilation error: 'TProgmemRGBGradientPalettePtr' does not name a type; did you mean 'TProgmemRGBGradientPaletteRef'?" All the necessary libraries are installed, so I really dont know what the problem is
