Could not find module ‘Test.QuickCheck’ on Windows
My ghci version is 8.4.3
I tried
stack install QuickCheck
Something was installed. But when I input import Test.QuickCheck, it tells Could not find module ‘Test.QuickCheck’ again. How can I fix it?

Firstly, stack install is not recommended for installing executables or libraries. Instead, there's a couple of things you can do to use the QuickCheck library:
- If you want to use
QuickCheckin a command such asstack ghciorstack ghc, you can add it as a--packageoption e.g. to run a REPL to play around withQuickCheckyou can usestack ghci --package QuickCheckand then writeimport Test.QuickCheck. - If you want to write a small one-file program using
QuickCheck, then you can runstack ghc --package QuickCheck -- MyProgram.hs(using the--packageoption from the last bullet point). Alternately, you can usestack's scripting functionality and include a line such as this at the top of your program:
-- stack --resolver lts-12.18 script --package QuickCheck
- If you want to use
QuickCheckin a large project, then add it as a dependency in yourmy-program.cabalorproject.yamlfile.
The same guidance applies to any package you may want to use.
