'Problems installing the python library for salvus

I'm having some problems installing the Python library for salvus (see installation instructions). When I use Conda to configure the salvus environment, the final step encounters a problem as the picture shows. When I run the command

jupyter nbextension enable skip-traceback/main

the error hint is

validating : problem found:\
require? X skip-traceback/main

enter image description here

And I ignore that, follow the next step, the other problem is showed. When I run the command

pip install ~/Salvus/python_packages/salvus-*.whl

trying to install the package, the file is not found. I don't understand where the file is nor where I need to download from.
