Cannot do any go command anymore

Question

Before it happened, what I am doing is trying to use the dep to manage my golang code dependency. What I found right now is I cannot do any command with go, even if I try to uninstall it with brew by brew uninstall go and do brew install go again.

If I am doing a go env it will show like this:

$ go env
go: cannot find GOROOT directory: /usr/local/cellar/go/1.13.1/libexec

$ ls /usr/local/Cellar/go/1.13.8/libexec/
CONTRIBUTING.md SECURITY.md bin     lib     robots.txt
CONTRIBUTORS    VERSION     doc     misc        src
PATENTS     api     favicon.ico pkg     test

$ go version
go: cannot find GOROOT directory: /usr/local/cellar/go/1.13.1/libexec

$ go build
go: cannot find GOROOT directory: /usr/local/cellar/go/1.13.1/libexec

$ echo $GOPATH
/Users/mymac/go

$ echo $GOROOT

$

What should I do and check?

Try this:

# Set variables in .bashrc file

# don't forget to change your path correctly!
export GOPATH=$HOME/golang
export GOROOT=/usr/local/opt/go/libexec
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOROOT/bin

Of course, you'll need to change "$HOME/golang" and "/usr/local/opt/go: to your actual path names.

From OP:

finally i solve this, can you help to update your comment then i will set it as SOLVED.

i use

export GOROOT=/usr/local/Cellar/go/1.13.8/libexec/

instead of

GOROOT=/usr/local/opt/go/libexec
