GOBREW_ROOT: unbound variable

[TimDurward]

Running into an issue during installation

curl -sLk https://raw.githubusercontent.com/kevincobain2000/gobrew/master/git.io.sh | sh
+ GOBREW_BIN_DIR=/Users/tdurward/.gobrew/bin
sh: line 8: GOBREW_ROOT: unbound variable

Looks like there was a recent change to the install script (git.io.sh) that added pipefail, with the flag -u, which treats unset variables as errors.

I was able to fix this locally by modifying the following...

- if [ -n "$GOBREW_ROOT" ]; then
+ if [ -n "${GOBREW_ROOT:-}" ]; then
    GOBREW_BIN_DIR=$GOBREW_ROOT/.gobrew/bin
fi

I should also mention that I'm running on Bash version 5.2.32.
