affected/package: go install not working

[parasit]

I am trying to set up a working environment on a new Mac (Studio M1 Max), the installation itself was fine, the test code compiles and runs fine, but I get errors when I try to install the basic tools. I tried both "automatically" via VSCode and manually, the effect is the same.

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

$ go version
go version go1.18 darwin/arm64
(installed by homebrew)

Does this issue reproduce with the latest release?

I think I'm using the latest version.

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

MacOs 12.3.1 (21E258) on Apple M1 Max

What did you do?

go install golang.org/x/tools/cmd/godoc@latest

What did you expect to see?

Nothing, installed tool/package.

What did you see instead?

go install golang.org/x/tools/cmd/godoc: mkdir /opt/homebrew/bin/go/: not a directory

When -x is added to command, returns (probably) the correct install log, but finally tries to create a directory that already exists.

lots of "packagefile ..."
...
mkdir -p $WORK/b001/exe/
cd .
/opt/homebrew/opt/go/libexec/pkg/tool/darwin_arm64/link -o $WORK/b001/exe/a.out -importcfg $WORK/b001/importcfg.link -buildmode=exe -buildid=V8q38yVb4G_5JkGEF4fC/OA9lzYVvTTtkH71bQxMG/V6MIBjHJ_aTlwLxGorxt/V8q38yVb4G_5JkGEF4fC -extld=clang /Users/bart/Library/Caches/go-build/7b/7b293eedbbf87742165174a3759d1bd550f1911e93c9d69f98ba6441b16ca03d-d

go install golang.org/x/tools/cmd/godoc: mkdir /opt/homebrew/bin/go/: not a directory

At this location is link to current installation:

❯ ls -l /opt/homebrew/bin/go
lrwxr-xr-x  1 bart  admin  24 24 mar 11:21 /opt/homebrew/bin/go -> ../Cellar/go/1.18/bin/go
❯ ls -l /opt/homebrew/bin/go/
lrwxr-xr-x  1 bart  admin  17 15 mar 15:08 /opt/homebrew/bin/go/ -> ../libexec/bin/go

P.S. Same effect is with all "default" tools: go-outline, gotests, gomodifytags, impl, goplay, staticcheck, gopls

Looks like you set your GOBIN path to a file; it needs to point to a directory.
