  Could not find directory of OpenSSL installation, and this `-sys` crate cannot
  proceed without this knowledge. If OpenSSL is installed and this crate had
  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
  compilation process.

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl
  and include information about your system as well as this message.

This should be caused by not installing SSL. What I want to ask is how to configure and install SSL on the Mac and run the IPFs service

[dariusc93]

You would have to install openssl on your mac if you have not done so already. This can be done via brew (eg brew install openssl) although i think the only crate that utilize openssl would be ipfs-http.

That's correct, libp2p does RSA with ring last time I looked. However please do not cargo install ipfs-http even if you set up all of the dependencies, if you want to use ipfs go with the original go-ipfs instead.

I understand. I have installed OpenSSL for my system. Thanks
