Test/Framework/Process.hs:45:48:
Ambiguous type variable `a0' in the constraints:
(Show a0)
arising from a use of `show' at Test/Framework/Process.hs:45:48-51
(Control.Exception.Exception a0)
arising from a use of `Control.Exception.handle'
at Test/Framework/Process.hs:45:5-28
Probable fix: add a type signature that fixes these type variable(s)
In the expression: show e
In the first argument of `return', namely
`([], show e, error (show e))'
In the expression: return ([], show e, error (show e))
cabal: Error: some packages failed to install:
