scipy installation error

I'm trying to run the project and I'm having an issue installing all the dependencies of the echo submodule, in particular I'm having issue with scipy, see error in the log:

I'm using python 3.6.3 with virtualenv on macOS. I tried to install the required dependencies (apt-get install libblas-dev liblapack-dev gfortran) using brew but it didn't find any.

Any suggestion?

Hi Luca,
ROBOH is in python 3:
https://github.com/OpenEdition/roboh/blob/master/INSTALL.txt#L5

But echo is in Python 2.7:
https://github.com/OpenEdition/echo/blob/master/INSTALL.txt#L15
It is why we use a socket to exchange data between this two process (ROBOH and its submodule echo) https://github.com/OpenEdition/roboh/tree/master/echosocket
