Compile error with Sparkfun pro micro

I’m very new to Arduinos, programming, PlatformIO, etc. I’m using VS Code on a Mac and unable to compile and upload to a Sparkfun pro micro.

platform = atmelavr
board = sparkfun_promicro16
framework = arduino
upload_port = upload_port = /dev/cu.usbmodem14301

Thanks in advance for the help!

See installation instruction of library dependencies => PlatformIO Registry

So silly, I misread the error, I thought there was a problem with the Sparkfun pro micro. The Adafruit Neopixel library install fixed the problem. Thank you!
