Problem description

Trying to update packages gets:

◍ golangci-lint-langserver
  ▶ # [6/6] Tried to link bin "golangci-lint-langserver" to non-existent target "golangci-lint-langserver.exe".
◍ delve
  ▶ # [6/6] Tried to link bin "dlv" to non-existent target "dlv.exe".
◍ gopls
  ▶ # [6/6] Tried to link bin "gopls" to non-existent target "gopls.exe".
◍ goimports
  ▶ # [6/6] Tried to link bin "goimports" to non-existent target "goimports.exe".

Expected behavior

Should work. I have all these installed.

I ran procmon to see what mason was doing and it is looking for the files in a staging subdirectory of it's install directory.

.data\nvim\Lazy\mason\staging

That was the only reference to any of the bin's it's trying to find. I haven't bothered to try to copy the files over or link them to this directory. The only thing in that subdirectory is gradle-language-server.

All files it is looking for are in the home dir:

L:\Programming\go\Home\bin>t
├── dlv.exe (size=21 MiB)
├── gofumpt.exe (size=5.9 MiB)
├── goimpl.exe (size=10 MiB)
├── goimports.exe (size=8.2 MiB)
├── golangci-lint-langserver.exe (size=3.7 MiB)
├── golangci-lint.exe (size=44 MiB)
├── gomodifytags.exe (size=4.2 MiB)
└── gopls.exe (size=40 MiB)

Which is linked by the GOPATH so I'm not sure why Mason isn't using the GOPATH to locate the files.

Affected packages

go

I ended up adding user.log(vim.inspect(ctx.package)) user.log(vim.inspect(spec.bin)) to link.lua to try to get more info on the issue:

log.fmt_debug("Expanded bin link %s -> %s", bin, target)
if not ctx.fs:file_exists(target) then
user.log(vim.inspect(ctx.package))
user.log(vim.inspect(spec.bin))

            return Result.failure(("Tried to link bin %q to non-existent target %q."):format(bin, target))
        end

In any case, after simply doing that everything was installed. The files were installed to .data\nvim\Lazy\mason\packages.

Not sure what it could have been. All I did was delete the mason.log and add those user.logs and it finally worked(after trying many other things that should have had no impact(mainly related on the go side by reinstalling go and the other packages and then trying to move things around to to try to get mason to fine the exe's). So, for now it is working. I likely must have "broke" something which fixed something when I was editing the link file(made a syntax error which prevent the package from fully loading).
