Hi,
Sorry to start with may be a trivial issue as this is the first time touching Purescript 
Chapter 2 says I need to clone, prepare, and run a test. I cannot even get this far 
https://book.purescript.org/chapter2.html#solving-exercises
% purs --version
0.15.15
% spago --version
0.93.28
To quote:
Now run the tests for this chapter:
cd exercises/chapter2
spago test
It says I should see the tests pass. I don’t:
% cd exercises/chapter2
spago test
Reading Spago workspace configuration...
❌ Couldn't parse Spago config, error:
Did not find `spago.yaml`. Run `spago init` to initialize a new project.
The configuration file help can be found here https://github.com/purescript/spago#the-configuration-file
I try a hunch:
% spago init
Initializing a new project...
Found PureScript 0.15.15, will use package set 50.11.0
Found existing directory "src", skipping copy of sample sources
Found existing directory "test", skipping copy of sample sources
Found existing file ".gitignore", not overwriting it
Found existing file ".purs-repl", not overwriting it
Set up a new Spago project.
Try running `spago run`
% spago install

Can someone please tell point me in the right direction for the step I missed? I naively expected this to just work but maybe I screwed up something? Or misunderstand something? It does not seem deps are installed rightly…
