glide version v0.12.3

Having what I believe is the same problem, during glide get and glide up:

[ERROR] Error looking for google/protobuf: Cannot detect VCS

Where does google/protobuf come from?

I boiled it down to some Go files in my repo (generated by Protobuf). If I stash them, glide works again. I can reproduce this consistently. They contain these imports:

import proto "github.com/golang/protobuf/proto"
import fmt "fmt"
import math "math"
import _ "github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis/google/api"
import google_protobuf "google/protobuf"
import google_protobuf2 "google/protobuf"

Now, obviously the last two imports aren't correct, but why on earth is Glide reading them?

also seeing the same error as @atombender with the import statements in generated proto go files

glide reads imports to determine what dependencies are actually required. The problem is those import paths.

You can always set an ignore in glide.yaml for google/protobuf - that should address that issue, at least.

The OP's issue is stranger - are you, perhaps, running that on a machine without a GOROOT set up, somehow? (not the env var, i mean literally no stdlib)

This was a good pointer for me. For me, glide tried to download the standard Go libs (as fmt, log, database/sql, ...) when I glided in a terminal hosted by GoLand.
When I did the same via the Windows console, it actually worked as expected. Looks like GoLand has set some ENV vars, which glide wasn't really understanding.
