What version of Go (go version) and dep (git describe --tags) are you using?

$ go version
go version go1.8 windows/386

$ git describe --tags
v0.1.0-175-gc79b048

Description

I first run dep init -v. Here the files:

• Gopkg.toml
• Gopkg.lock
• Output of dep init -v

Dep automatically choose the default branch of Gin project (master), but I need develop. So I changed Gopkg.toml from:

[[constraint]]
  name = "github.com/gin-gonic/gin"
  version = "1.1.4"

To:

[[constraint]]
  branch = "develop"
  name = "github.com/gin-gonic/gin"

Then I runned dep ensure and got the panic.

• Output of dep ensure -v
