1411897 - no attribute 'get_debugger_info' when trying to launch named debugger via mach run

Status: RESOLVED DUPLICATE of bug 1411776

(Firefox Build System :: General, defect)

Description

[Henri Sivonen (:hsivonen)]

On Ubuntu 17.10:

$ ./mach run --disable-e10s --debug --debugger=rr
Error running mach:

    ['run', '--disable-e10s', '--debug', '--debugger=rr']

The error occurred in the implementation of the invoked mach command.

This should never occur and is likely a bug in the implementation of that
command. Consider filing a bug for this issue.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

AttributeError: 'module' object has no attribute 'get_debugger_info'

  File "/opt/Projects/gecko/python/mozbuild/mozbuild/mach_commands.py", line 1420, in run
    self.debuggerInfo = mozdebug.get_debugger_info(debugger, debugger_args)

$ ./mach run --disable-e10s --debug
Error running mach:

    ['run', '--disable-e10s', '--debug']

The error occurred in the implementation of the invoked mach command.

Smells like a dupe of bug 1411776. Reopen if you can repro on head of mozilla-central.
