revised Non linear transformation satisfying $T(x+y)=T(x)+T(y)$
Previous comment on automorphisms of $\mathbb{C}$ removed as not really relevant.

comment Short Five Lemma for Fibrations
OK I understand. Thanks. In that case I think you can do $E = E' = \mathbb{R}^2$, $B = B' = \mathbb{R}$ and $F = F' = \mathbb{R}$ with the projections to $B$ being the projection on the first factor and the basepoint being $1$. Define $E \to E'$ to be $(x, y) \mapsto (x, xy)$. This is identity map on the fibre and the base but not invertible.
