Wrangler: document openssl fix

[TownLake]

I attempted the tutorial here but ran into a problem with openssl:
I installed cargo
$ curl https://sh.rustup.rs -sSf \| sh
and configured my shell with:
$ source $HOME/.cargo/env
I then succesfully installed wrangler with
$ cargo install wrangler
and tried to generate a "Hello, World" project with:
$ wrangler generate demo
However, that throws an error:

dyld: Library not loaded: /usr/local/opt/[email protected]/lib/libssl.1.1.dylib
Referenced from: /Users/userspace/Library/Caches/.wrangler/cargo-generate-2665b6ba17ab8008/cargo-generate
Reason: image not found
Error: ErrorMessage { msg: "failed to execute /Users/userspace/Library/Caches/.wrangler/cargo-generate-2665b6ba17ab8008/cargo-generate generate --git https://github.com/cloudflare/rustwasm-worker-template --name demo: exited with signal: 6" }

So I instead tried
$ cargo install cargo-generate
which led to a similar error:

It looks like you're compiling on macOS, where the system contains a version of
OpenSSL 0.9.8. This crate no longer supports OpenSSL 0.9.8.

As a consumer of this crate, you can fix this error by using Homebrew to
install the openssl package, or as a maintainer you can use the openssl-sys
0.7 crate for support with OpenSSL 0.9.8.

Unfortunately though the compile cannot continue, so aborting.

I just ran into the same issue and got it working by installing [email protected] via homebrew:

brew install [email protected]

afterwards:

$ wrangler generate demo
⬇️ Installing cargo-generate...
🐑 Generating a new rustwasm worker project with name 'demo'...
🔧   Creating project called `demo`...
✨   Done! New project created /Users/user/tmp/demo

That did it - solved my issue as well. Thanks for the help!

hey folks! would either of you be interested in updating the README to include the instruction for fixing this? i think it'd be valuable! (if not, i'll do it, but i'd love to have more contributors to the project <3)
