Using holochain on OSX Big Sur (without nix)

Until we find a fix for using holonix on Big Sur (see Holonix fails on latest MacOS: Big Sur)

…those of us on Big Sur who are relentlessly trying to develop HC apps have a few options:

  1. Use Docker
  2. Use a vitualization tool like Multipass ( see my post within Is there a hello world or simple chat app for RSM? )
  3. Go straight to raw rustup/cargo etc on the mac – ie no nix, and no linux-within-mac

Any of these should be considered workarounds until holonix is fixed, as that is the blessed path.

Having said that, after trying all three, I’ve found #3 to be the simplest and fastest.

Here’s what I did in a nutshell:

curl https://sh.rustup.rs -sSf | sh
rustup update            # probably not needed
rustup install stable
rustup default stable

git clone https://github.com/holochain/holochain
cd holochain
cargo install --path crates/holochain
cargo install --path crates/dna_util
cargo install --path crates/hc
cargo install --git https://github.com/holochain/lair
yes | holochain -i

I copied your suggested commands and entered them all at once in my terminal. Everything seems to have worked except for the lair.

Conductor ready.

Thanks @bierlingm I see errors like this too, but everything seems to work ok… does the holochain app in question work for you?

Haven’t tried running any app with it yet. Got any you’re running that I could try out?

Sure, this one is simple and worked for me:
