I do not think that you have to create example.com/greetings but greetings.
In my environment, the directory structure was as follows after finishing this page.

$ tree .
.
├── greetings
│   ├── go.mod
│   └── greetings.go
└── hello
    ├── go.mod
    ├── hello
    └── hello.go

2 directories, 5 files 

If you would like to create the directory structure, example.com/greetings, you have to modify go.mod in hello/go.mod as follows.

module hello

go 1.15

replace example.com/greetings => ../example.com/greetings

I hope this helps you.

I agree that the tutorial should work as it is and you shouldn't need to mkdir -p example.com/greetings. My guess is that you missed some of the steps, or did something wrong.

Suggestion: try to re-do the tutorial from scratch. If you still get that error, post your directory structure like @task4233 did above, and the content of all the files; and we may be able to understand what went wrong.

I was doing the tutorial in $GOPATH/src making me able to call the greeting module by creating the folder structure. Instead, I should follow the instruction to work on the home directory. Thank you everyone.

I am trying to follow the tutorial from "https://golang.org/doc/code#Workspaces" and I am getting:

hello.go:6:2: cannot find package

In no place there is a mention that a $GOPATH/src has to be created. What is more I don't find a folder named example.com/user/hello. Where I supposed to be. ?

go version go1.16.5 linux/amd64 in Ubuntu 20

@sylviankahane It doesn't need to exist, you probably missed a step
