[Question][Hw0-2] oUnit not found

Hello, I install ocaml environment myself with 'DiskuvOCaml', but there is some problem. Testing with utop is fine, but an error occurs when I enter "dune exec test/sigmaTest.exe" in terminal like this:

dune exec test/sigmaTest.exe     
File "test/dune", line 1, characters 40-45:
1 | (test (name sigmaTest) (libraries sigma oUnit) (modules sigmaTest))
                                            ^^^^^
Error: Library "oUnit" not found.
-> required by _build/default/test/sigmaTest.exe

---

Even though I enter "opam install oUnit", it does not change. How can I fix it? Thank you.
