Conda environment error trying to build website locally

[TomNicholas]

I tried to follow the instructions in the readme and got this

(base) tom@Toms-MacBook-Air zarr-developers.github.io % conda create -n zarr.dev -c conda-forge rb-bundler c-compiler compilers cxx-compiler
Channels:
 - conda-forge
 - defaults
Platform: osx-arm64

LibMambaUnsatisfiableError: Encountered problems while solving:

Could not solve for environment specs
The following packages are incompatible
└─ rb-bundler =* * is not installable because there are no viable options
   ├─ rb-bundler 2.0.2 would require

Looks like those instructions haven't been updated in 4 years...

I went down a rabbit hole of installing brew, ruby, and gem myself and it still didn't work.

sorry this was frustrating. i recall having similar problems before with ruby projects. seems like this is something we need to deal with.

I assume the commands in https://github.com/zarr-developers/zarr-developers.github.io/blob/main/.readthedocs.yml are the only really tested method.

I'm happy to set up a docker if that would be useful.

[TomNicholas]

I'll look at that.

Tbh I don't think this is super important for me personally - I was able to generally add what I wanted in #131 even without being able to build it locally.
