I am using dep to manage the dependencies of a Go tool I'm writing. This tool uses https://github.com/desertbit/grumble as an dependency. This in turn uses https://github.com/chzyer/readline as a dependency. The problem is that when trying to run my tool I get the following error: vendor/github.com/desertbit/grumble/app.go:295:20: unknown field 'HistorySearchFold' in struct literal of type readlin
