I'm getting errors when trying to run the `generate-resolves` goal in `2.17.*` .
```19:42:06.01 [ERROR] 1 Exception encountered:

Engine traceback:
  in `generate-lockfiles` goal

ProcessExecutionFailure: Process 'Generate lockfile for python-default' failed with exit code 2.
stdout:

stderr:
usage: pex_v2.1.130 [-h] [-V] {interpreter,lock} ...
pex_v2.1.130: error: a subcommand is required```

I am also having trouble migrating to the new resolved-based lockfiles for tools -- Pants complains the resolve does under `[tool].install_from_lockfile` does not exist even though it is clearly defined under `[python].resolves`.  Will revisit that once I get past the above issue.

Hey <@U02M2Q21AJF> would love more data on that error, since it seems pretty concerning that Pants is issuing an incorrect command to pex somehow
