Go Glide Error "The system cannot find the path specified" - go

Question

I am trying to manage my Go project with glide.
I executed glide update, but got The system cannot find the path specified error as below.
C:\path\to\myproject\src>glide update

[ERROR] Failed to retrieve a list of dependencies: Error resolving imports
Actually there is not C:\Users\myhome\.glide\cache\src\https-github.com-golang-protobuf\ptypes directory, but I can not understand why this directory is missed.
My glide.yaml is as follows.
package: .
import:
- package: cloud.google.com/go
version: ^0.7.0
subpackages:
- bigquery
- civil
- package: github.com/gin-gonic/gin
version: ^1.1.4
- package: golang.org/x/net
subpackages:
- context
- package: golang.org/x/oauth2
subpackages:
- google
- package: google.golang.org/api
subpackages:
- iterator
- package: google.golang.org/appengine
version: ^1.0.0
subpackages:
- datastore
- log
- memcache
- remote_api
How can I fix?

Answer 1

I found the github.com/golang/protobuf version 2402d76f3d41f928c7902a765dfc872356dd3aad which github.com/gin-gonic/gin wants does not has ptype. I added below lines to glide.yaml.
- package: github.com/golang/protobuf
version: b50ceb1fa9818fa4d78b016c2d4ae025593a7ce3
b50ceb1fa9818fa4d78b016c2d4ae025593a7ce3 is the current newest commit.
The error has gone. But I am not sure this is the straightforward way because I still have the warning below.
[WARN] Conflict: github.com/golang/protobuf rev is currently b50ceb1fa9818fa4d78b016c2d4ae025593a7ce3, but github.com/gin-gonic/gin wants 2402d76f3d41f928c7902a765dfc872356dd3aad
If another way is desirable, please advise me.
