can not fetch GitHub new release version

[songjiayang]

Go Version: 1.12.0
ErrorMessage:

go: finding github.com/mattn/go-isatty v0.0.7
go: github.com/mattn/go-isatty@v0.0.7: unexpected end of JSON input
go: error loading module requirements

But it can fetch the latest git summit hash.

export GOPROXY=https://goproxy.io
go get github.com/mattn/go-isatty@v0.0.7   

Just try it

I think this is a cache problem, now it works.
