@fredchenbj Thanks for your feedback!
And what is your go version?

[fredchenbj]

@rleungx go version go1.11.4 darwin/amd64

[rleungx]

@fredchenbj Can you try to run go clean -modcache first?
There is a known issue for this problem. See golang/go#29281.

[fredchenbj]

@rleungx after I run go clean -modcache, the above error still occurs.

@fredchenbj Can you remove go.sum and regenerate it to see if it can success? Or use go 1.11.2 instead.

[fredchenbj]

@rleungx I change go.sum with downloaded checksum, it is ok now.
