Building hugo for purposes of contribution doesn't work (deps not installed?)

I am having a difficult time following what are you doing.

Assuming your GOPATH is $HOME/go, the process should be:

  1. Fork the Hugo repository
  2. Create a directory outside of the GOPATH ($HOME/code)
  3. cd into the directory you just created
  4. Clone your fork
  5. cd into the source directory ($HOME/code/hugo)
  6. Create a new branch with a meaningful name (git checkout -b fix/correct-typo)
  7. Make your changes.
  8. Compile (go install -tags extended)
  9. Test (mage -v test)
  10. Commit your changes locally
  11. Push the branch to your repository
  12. Head over to the Hugo repository to create the pull request
