seems like crates.io may have had some down time or an incident when this happened. the real bug here is that it was attempting to install wasm-pack but it didn't need to be. this is similar to #768! @EverlastingBugstopper as you work on 768 can you also take a look at this? will be in the exact same part of the (bad) code (i wrote) :P

Same issue here - a way to bypass wasm dependencies would be great (don't need them)

first attempt to do this in #849 didn't pan out. will try again with a new approach
