Environment

Ubuntu 16.04
go version go1.9 linux/amd64

Steps

  1. go get -u github.com/John-Lin/tinynet
  2. execute tinynet/example/topo-single-8.go

Issue

When I type go run topo-single-8.go, I got following error.

This issue only happens if I install tinynet via go get.

And how to avoid this error?

hwchiu commented

I try to download source from git and use govendor sync to install dependency packages and it works now.

@hwchiu thanks. I should add a dependencies installation in README. If you like create a PR for that.
@07skat Use govendor and govendor sync to install dependencies.
