let rec fib n = if n < 2 then n else fib (n - 1) + fib (n - 2);;
How to solve problems with opam?
On Linux and macOS, this will be the ~/.opam directory, which means you don't need administrative privileges to configure it. If you run into problems configuring opam, just delete the whole ~/.opam directory and start over.
