‘readsPrec1’ is not a (visible) method of class ‘Read1’ #163

Closed robstewart57 closed 8 years ago

robstewart57 commented 8 years ago

Hi,

I'm using GHC 7.10. When running cabal install I get the error:

src/Control/Monad/Exceptable.hs:153:61:
    ‘readsPrec1’ is not a (visible) method of class ‘Read1’

What should I do to solve this issue?

The full error message is:

That's a consequence of a breaking change in the transformers package, introduced in transformers-0.5.0.0. The latest llvm-general adds the constraint transformers < 0.5 to express its dependency on the older API.

Ah excellent, then I'll change my projects to rely on llvm-general > 3.5.1.2.
