[1 of 1] Compiling Text.URI         ( Text/URI.hs, dist/build/Text/URI.o )

Text/URI.hs:246:13: error:
    • Ambiguous type variables ‘s0’, ‘m0’ arising from a use of ‘satisfy’
      prevents the constraint ‘(Text.Parsec.Prim.Stream
                                  s0 m0 Char)’ from being solved.
      Relevant bindings include
        reservedP :: Text.Parsec.Prim.ParsecT s0 u m0 Char
          (bound at Text/URI.hs:246:1)
      Probable fix: use a type annotation to specify what ‘s0’, ‘m0’ should be.
      These potential instances exist:
        instance [safe] Monad m => Text.Parsec.Prim.Stream [tok] m tok
          -- Defined in ‘Text.Parsec.Prim’
        ...plus four instances involving out-of-scope types
        (use -fprint-potential-instances to see them all)
    • In the expression: satisfy isReserved
      In an equation for ‘reservedP’: reservedP = satisfy isReserved
