Can not import thetatoken/theta

[mutobui]

I'm trying to import thetatoken/theta by following:

terminal:
$ go get github.com/thetatoken/theta-protocol-ledger

go.mod:
module github.com/demo/theta-go

replace github.com/thetatoken/theta-protocol-ledger => github.com/thetatoken/theta master

go 1.14

require (
)

Err:
