Hi,

this often happens when you extract a new Go version over the old one (in the same folder).

Please delete the whole folder and try to install Go again. For example, if it was in /usr/local/go

$ sudo rm -r /usr/local/go

and then re-download and extract the new Go version.

I'm closing this issue, since I believe this is a problem with the Go installation on your machine, but feel free to comment here if the error persists after you completely deleted Go and re-installed it from scratch.

useful!
