golang fish shell config

config.fish

# config file
# vim ~/.config/fish/config.fish

# reload the config
# source ~/.config/fish/config.fish

# set the workspace path
set -x GOPATH /users/my-username/go

# add the go bin path to be able to execute our programs
set -x PATH $PATH /usr/local/go/bin $GOPATH/bin

this worked for me given i installed it in the default location /usr/local/go and my go libraries will go into golibs

set -x GOROOT  /usr/local/go
set -x PATH $PATH $GOROOT/bin

set -x GOPATH $HOME/golibs
set -x PATH $PATH $GOPATH/bin

I'm getting an error go: go: could not create module cache: mkdir /usr/local/go/pkg/mod: permission denied
