When I run 'make' on the code in Chapter 3 (Introduction), I don't see the messages shown on page 24, i.e.
3 of 3 tests failed:
1) exchange buy should add a BUY nockmarket order:
ReferenceError: exchange is not defined
Instead, I see the following messages:-
...
✖ 3 of 3 tests failed:
Makefile:2: recipe for target `test' failed
make: *** [test] Error 3
I'm using the files from the code download and 'make' is run via Cygwin.

Is there something wrong with my setup?
