Is the readme install instruction still correct?

[DWShuo]

just running go get github.com/trezor/trezord-go gives you the trezord-go executable under $GOPATH/bin

when i run go build github.com/trezor/trezord-go i get the following error:

no required module provides package github.com/trezor/trezord-go: go.mod file not found in current directory or any parent directory; see 'go help modules'

What happens if you run go mod download and try build then?

What happens if you run go mod download and try build then?

where do i run this command?

[tsusanka]

Now that I think of it I think it should not be needed. @DWShuo what Go version do you have? Are you on current master?

[DWShuo]

@tsusanka yes currently on master, with go version go1.16.2 linux/amd64

Well looks like this may help,... , force env GO111MODULE to auto

Thanks.

Indeed GO111MODULE needs to be set to auto for new versions of go.

Fixed in dc487a0c5350f1f06d612450db5fcbd9bba65136
