commit a9cc84f9681ff1fda28f316c70d932af6f54b187

OS X 10.10, installed by

python setup.py install

error:

Then I changed to load from git repo

    self.adaptor = self.pm.debugger_plugin_for_host('lldb').adaptor_class()
AttributeError: 'NoneType' object has no attribute 'adaptor_class'

I read plugin.py, and found if I change

    def debugger_plugin_for_host(self, host=None):
        """
        Find a debugger plugin that supports the debugger host.
        """
        return self.debugger_plugins[host]

to

    def debugger_plugin_for_host(self, host=None):
        """
        Find a debugger plugin that supports the debugger host.
        """
        return self._debugger_plugins[host]

This error is gone.

Then comes voltron status in lldb

Something seems to be wrong with the installation.

If you install in dev mode with python setup.py develop it should work for now. I’ll take a look.

Thanks.
