Can not install go module ! what's problem ?

[watangca]

What version of Go are you using (go version)?

$ go version
go version go1.16 darwin/amd64

Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?

The error says "read-only file system"; it looks like Go cannot write files where it needs to. This is probably an issue with your machine, not a Go bug. Does that folder exist? Can you write on it?

From the go env output, I believe this is a typo in your GOPATH setting.

I see (emphasis added):

GOCACHE="/Users/folls/Library/Caches/go-build"
GOMODCACHE="/Users/folls/go/pkg/mod"

but:

GOPATH=/User/folls/Desktop/go

So the problem here seems to be that /Users has been typo'd as /User, and the go command cannot create the top-level /User directory (no s) because your root directory is (correctly) not writable.
