If anyone's trying out the new opam switch, I found it helpful to use: env OCAMLPARAM="alert=-unsafe_multidomain,_," opam install cohttp-lwt-unix Because alerts are promoted to errors, they break existing package installs unnecessarily. The OCAMLPARAM environment variable just forces that alert to be disabled and allows the package installation to continue.
