What is the current thinking and approach to installing Discourse on macOS for development purposes? I’ve tried installing via the official GitHub documented instructions in the article - [Beginners Guide to Install Discourse on macOS for Development](https://meta.discourse.org/t/beginners-guide-to-install-discourse-on-macos-for-development/15772) but that doesn’t work.
3 errors are reported when trying to install the `cppjieba_rb-0.3.3 gem`.
Anyone else experienced this recently?

What is the output of `gem install cppjieba_rb`?

Did you figure this out? I hit the same issue when I switched from bash to zsh and forgot to setup [rbenv](https://github.com/rbenv/rbenv). Once I was using rbenv again all went back to normal.
The system Ruby on macOS seems to be problematic from time to time.

I didn’t figure it out. Did you do more than just install rbenv as part of the Discourse Dependency Install script? That’s all I did, because there aren’t any other instructions.

My dev environment was setup a long time ago, so I’m not sure. I don’t suspect I did anything more at the time, but maybe something changed in macOS since then.
I guess you can check if rbenv is setup… if you run `nano ~/.bash_profile` you should see something like this:
```plaintext
# load rbenv
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init - --no-rehash)"
```
You can also check `rbenv versions` to see which version is currently selected (it’s the one with the asterisk next to it). If it’s `system` you’ll want to change it… 2.6.1 is working fine for me. (`rbenv install 2.6.1` and then `rbenv global 2.6.1`)
