[ 1 of 17] Compiling Language.LaTeX.Types ( Language/LaTeX/Types.hs, dist/build/Language/LaTeX/Types.o )

Language/LaTeX/Types.hs:432:42: error:
    • No instance for (Alternative LatexM)
        arising from the 'deriving' clause of a data type declaration
      Possible fix:
        use a standalone 'deriving instance' declaration,
          so you can specify the instance context yourself
    • When deriving the instance for (MonadPlus LatexM)
