Tty.c: loadable library and perl binaries are mismatched

Question

I upgraded Ubuntu from zesty to bionic. In the process perl was upgraded from 5.24.1 to 5.26.1. Now I am getting this error when I try to install Expect.

Tty.c: loadable library and perl binaries are mismatched 

I have re-installed IO::Tty and that says it has installed correctly. There are other modules that are reporting similar errors.

Here is the full output from the failed Expect install.

Answer 1

I deleted my ~/perl5 directory. Expect installed fine.
