Error compiling Marlin-bugfix-2.0

I was able to compile only a few days ago with no issues.
Today I tried and I got the error:


HARDWARE: LPC1768 100MHz, 31.80KB RAM, 464KB Flash
DEBUG: Current (cmsis-dap) On-board (cmsis-dap) External (blackmagic, jlink)
PACKAGES: framework-arduino-lpc176x 0.1.3, toolchain-gccarmnoneeabi 1.80201.190214 (8.2.1)
Converting Marlin.ino
'arm-none-eabi-g++' is not recognized as an internal or external command,
operable program or batch file.
*** Error 1

After that I checked for libraries that needed updating. There were several but updating them did not alleviate the error.
Any ideas?
