Just downloaded and installed Visual Studio Code on OS X 10.10.3.
I\'ve managed to partially follow the installation instructions for ASP.NET 5.
What I fail with
To answer my own question:
What helped, was Jed Grant's comment and link to this GitHub discussion.
I did the following in a terminal:
source dnvm.sh dnvm upgrade -u
And suddenly the "dnu" command was available so that I could run
dnu restore
As the installation instructions told me.
