[ERROR] No package named wasm_of_ocaml-compiler found.

[jayphelps]

When using the README install instructions once I get to opam install wasm_of_ocaml-compiler I get the error [ERROR] No package named wasm_of_ocaml-compiler found.

I've tried restarting my shell env, no effect. Also tried the same steps over again, three times.

@JasonGross figured out improved installation instructions in #13 (the PR needs rebasing though)
Can you try those instructions?

@jmid @JasonGross Those instructions seem to get further since they don't error with No package named but that final command still does fail with this:

➜  ocaml opam install wasm_of_ocaml-compiler

But putting wasm-merge from Binaryen in my PATH did solve it. So if wasm-merge is a requirement that probably should either be part of the install or stated as a pre-req.

Thanks folks!
