Unordered collections 1.8.3 source - Module Data.Hashable has been defined multiple times

Help
#1

Hi

In Chapter 6 of the book, while running spago repl I get this error

Error found:
at .spago\unordered-collections\v1.8.3\src\Data\Hashable.purs:5:1 - 125:43 (line 5, column 1 - line 125, 
column 43)

  Module Data.Hashable has been defined multiple times

And spago build

Error found:
at .spago\unordered-collections\v1.8.3\src\Data\Hashable.purs:5:1 - 28:49 (line 5, column 1 - line 28, column 49)

  Module Data.Hashable has been defined multiple times

This works for me:

git clone https://github.com/purescript-contrib/purescript-book.git
cd purescript-book/exercises/chapter6
spago repl

This type of issue is likely better reported in the book’s issue tracker.
