Goenv is a Go package that provides virtualenv-like functionality for Go projects, isolating dependencies into workspaces for safer and simpler management.

  • Similar functionality to Python’s virtualenv and virtualenvwrapper.
  • Separates development directory from import path — e.g., develop in ~/myproject, but import from
  • Isolates dependencies from other projects.
  • Does not interfere with any go command functionality.
  • Written in Go, installable with go get.
