[gccversion] Error 127

[muscle-rabbit]

1, I run the script to use my fourier keybord.

$ ./util/qmk_install.sh
$ make fourier:valgrahf

2, However, I got the err.

$ make fourier:valgrahf
QMK Firmware 0.6.137
Making fourier/rev1 with keymap valgrahf

/bin/sh: avr-gcc: command not found
sh: avr-gcc: command not found

make[1]: *** [gccversion] Error 127
make: *** [fourier:valgrahf] Error 1

3. I refer to this reddit article which is same error as me.
   I run the script which is written in the article.

$ brew reinstall avr-gcc@7
$ brew install crosspack-avr
$ brew update
$ brew upgrade
$ brew link avr-gcc
$ ./util/qmk_install.sh

the script above's outputs

$ ./util/qmk_install.sh

==> Caveats
avr-gcc@7 is keg-only, which means it was not symlinked into /usr/local,
because it might interfere with other version of avr-gcc. This is useful if you want to have multiple version of avr-gcc installed on the same machine.

If you need to have avr-gcc@7 first in your PATH run:
  echo 'export PATH="/usr/local/opt/avr-gcc@7/bin:$PATH"' >> ~/.bash_profile

For compilers to find avr-gcc@7 you may need to set:
  export LDFLAGS="-L/usr/local/opt/avr-gcc@7/lib"

What should I do? Please help.

Try running echo 'export PATH="/usr/local/opt/avr-gcc@7/bin:$PATH"' >> ~/.bash_profile, and reopen the terminal.

Awesome, glad to heat that this fixed the issue!

And yeah, the AVR GCC thing has been an issue for a bit now.
