如何修复 $GOPATH/go.mod 存在但不应该存在 - Linux Fedora

Question

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

Answer 1

GOPATH defaults to $HOME/go on Unix.

Remove the file $HOME/go/go.mod or explicitly set $GOPATH to a different directory.

Answer 2

$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
