Please answer these questions before submitting your issue. Thanks!

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

go version devel +8a33045 Fri Jul 13 03:53:00 2018 +0000 linux/amd64

Does this issue reproduce with the latest release?

No, working with go tip.

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

GOARCH="amd64"
GOBIN=""
GOCACHE="/home/ubuntu/.cache/go-build"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/tmp/tmp.Q82kVMHRrz"
GOPROXY=""
GORACE=""
GOROOT="/home/ubuntu/usr/gotip"
GOTMPDIR=""
GOTOOLDIR="/home/ubuntu/usr/gotip/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
CXX="g++"
CGO_ENABLED="1"
GOMOD="/tmp/tmp.Q82kVMHRrz/hello/go.mod"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build448197327=/tmp/go-build -gno-record-gcc-switches"

What did you do?

cd `mktemp -d`
export GOPATH=$PWD
mkdir hello
cd hello
vgo mod -init -module example.com/hello
go get rsc.io/quote
cat go.mod

gives:

module example.com/hello

require rsc.io/quote v1.5.2 // indirect

Then:

go get rsc.io/quote@none

What did you expect to see?

Successful removing of dependency, per go help mod:

The -require=path@version and -droprequire=path flags
add and drop a requirement on the given module path and version.
Note that -require overrides any existing requirements on path.
These flags are mainly for tools that understand the module graph.
Users should prefer 'go get path@version' or 'go get path@none',
which make other go.mod adjustments as needed to satisfy
constraints imposed by other modules.

What did you see instead?

go: finding rsc.io/quote none
go get rsc.io/quote@none: unknown revision none

Technically a dup of #26342, but yours is more precise and searchable. 🙂
