I am new to Golang, I am following this tutorial https://golang.org/doc/tutorial/getting-started but for some reason I keep getting this message every time I try to run the code:
$GOPATH/go.mod exists but should not
I have tried to look at answers like this one: https://stackoverflow.com/a/62062562/9785222 but I dont understand what is GOPATH and where is it.
I am using Vi as an editor on Linix Fedora
GOPATH defaults to $HOME/go on Unix.
Remove the file $HOME/go/go.mod or explicitly set $GOPATH to a different directory.
$GOPATH should point out to the src directory, in my case in Debian, I set $GOPATH to /usr/local/go/src and the problem was solved.
export $GOPATH=/usr/local/go/src
What is GOPATH ?
GOPATH is a variable that defines a folder, under which GO expects our code to reside . For more details, you can check this link
