cannot install delve - could not import internal/goarch

[FoxAndFoxElectrics]

I raised this on the delve help forum
go-delve/delve#3317
and they redirected me here

Hi all, probably doing something stupid, but this is what I tried:

What version of Go are you using (go version)?

go version
go version go1.20.2 windows/amd64

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

New build i9 13900K Windows 10: 10.0.19045
32GB RAM, tons of hard drive space.
This is a new PC and hasn't had GO installed on it before.

What did you do?

Ran the installer go1.20.2.windows-amd64
Checked version:

go version
go version go1.20.2 windows/amd64

Tried to install delve

go clean -modcache
go install github.com/go-delve/delve/cmd/dlv@latest

What did you expect to see?

Delve install OK

What did you see instead?

could not import internal/goarch (EOF) and various others...

[seankhliao]

looks like a corrupt installation of go

[omarcosr]

Same problem here, did you find a solution?

[FoxAndFoxElectrics]

I'm so sorry I didn't make a note of the solution. I suspect it was a question of re-installing Golang, but a version that was (fully) supported by VSCode. Currently I am using 1.18.5 so my suggestion would be to try that. It's a pain as VSCode tries to update to latest. Though of course it may be something else that has been fixed/broken in the intervening 10 months. Good luck!
