[Health-dev] Exception: health_inpatient unmet dependencies: ['health']

[raziabe]

Hello All.

I was updated my gnuhealth to new version. But, I didn't found how to 
update the other modules.

So, I decide to try to install not update.
I using pip to installation the new version gnuhealth 1.6.4 with 
trytond-2.6.1.

Everything is ok for the installation.

but, when I booting the server, with trytond, I found some error.

there are the errors :
