Okay, I’ll bite! Simple tutor-newbie question of the day.

In the [Running Open edX on the master branch (“nightly”)](https://docs.tutor.overhang.io/tutorials/nightly.html#nightly) tutorial it says to run these commands after pip installing:

```auto
tutor dev launch
tutor dev run lms bash

```

When I run `tutor dev launch`, I get:

```auto
❯ tutor dev launch
Usage: tutor dev [OPTIONS] COMMAND [ARGS]...
Try 'tutor dev -h' for help.

Error: No such command 'launch'.

```

And then `tutor dev -h` says:

```auto
❯ tutor dev -h
Usage: tutor dev [OPTIONS] COMMAND [ARGS]...

  Run Open edX locally with development settings

Options:
  -h, --help Show this message and exit.

Commands:
  bindmount Copy the contents of a container directory to a...
  createuser Create an Open edX user and interactively set their...
  dc Direct interface to docker-compose.
  exec Run a command in a running container
  importdemocourse Import the demo course
  init Initialise all applications
  logs View output from containers
  reboot Reboot an existing platform
  restart Restart some components from a running platform.
  run Run a command in a new container
  runserver Run a development server
  settheme Assign a theme to the LMS and the CMS.
  start Run all or a selection of services.
  stop Stop a running platform

```

So… what am I missing here? 😄 Is the doc outdated? Have I somehow screwed up installation of the `tutor` executable?

Thanks!

Maybe the wrong version of tutor somehow? What do you get when you check the version? My recent install is:

```auto
❯ tutor --version
tutor, version 16.0.2-nightly

```

Aha! I have version 12.x on my path somehow, despite having pulled down the nightly branch (which is also 16.0.2). Perhaps from some prior install attempt. Thanks @dave!
