Training recipes fails with poor error message

Project Member Reported by tansell@chromium.org, May 4 2017 
I assume I need to install vpython somehow?

Did you solve this issue?
I have the same issue after I pull the master today (it works last week). Using following:

(in build_internal/scripts/slave)
python recipes.py --use-bootstrap test train

Traceback (most recent call last):
  File "recipes.py", line 207, in <module>
    sys.exit(main())
  File "recipes.py", line 193, in main
    cwd=os.path.dirname(__file__)).strip())
  File "recipes.py", line 129, in _git_output
    return subprocess.check_output(argv, **kwargs)
  File "/usr/lib/python2.7/subprocess.py", line 566, in check_output
    process = Popen(stdout=PIPE, *popenargs, **kwargs)

    raise child_exception

Is this the same error? The stack traces don't look the same to me.

cc'ing a couple of others to look at vpython trace above.

Comment 4 by hmchen@chromium.org, May 9 2017 

Sorry for the confusion. That is a different error. :)
My error is solved by using "./recipes.py" instead of "python recipes.py". Free feel to delete my comments.

Comment 5 by iannu...@google.com, May 9 2017 

You shouldn't need to install vpython; it should be automatically pulled.

However, that command line looks suspicious... you shouldn't ever need to pass --package to that recipes.py script. Try:

  $ ./scripts/slave/recipes.py --verbose test train

Which should do what you want.

@hmchen, I think that's actually a different bug; I'll have a CL to fix it.

Comment 7 by iannu...@google.com, May 9 2017 

Ok, hmchen, please pull and try again, it should be fixed now.

Comment 8 by d...@chromium.org, May 9 2017 

RE the initial bug, it looks like the line that is failing is the bootstrap call to "cipd". The recipe bootstrap assumes that the "cipd" tool is available on PATH. Is it possible that you don't have "depot_tools' on PATH, or that you have a very old "depot_tools" checkout?

Status: Fixed (was: Untriaged)
Closing as fixed.
