OpenEmbedded Yocto

I just followed the direction on installing yocto and bitbake for the openembedded.
When I got to the step where you do your first bitbake I get the following error:

ERROR: Unable to parse /home/rjberry/oe-core/oe-rpb/bitbake/lib/bb/
Traceback (most recent call last):
File “/home/rjberry/oe-core/oe-rpb/bitbake/lib/bb/”, line 400, in DataSmart.expandWithRefs(s="${@os.path.dirname(bb.utils.which(d.getVar(‘PATH’),‘bitbake’))}:${HOSTTOOLS_DIR}", varname=‘PATH[:=]’):
except Exception as exc:
> raise ExpansionError(varname, s, exc) from exc

bb.data_smart.ExpansionError: Failure expanding variable PATH[:=], expression was ${@os.path.dirname(bb.utils.which(d.getVar(‘PATH’),‘bitbake’))}:${HOSTTOOLS_DIR} which triggered exception TypeError: getVar() missing 1 required positional argument: ‘expand’

Can someone please help? I am building for the Dragonboard 410c
