Hello, I am running a workflow on GitHub Actions and I am looking to run some R code using a package called “rayshader” which requires something called “XQuartz” to be installed.

I am able to install XQuartz successfully using the command:

brew cask install xquartz

The install seems to work based on the results I’m seeing:

But when the code gets to the step that needs XQuartz, I am getting the following error:

error: X11 not found; XQuartz (from www.xquartz.org) is required to run rgl.

Thoughts on why that may be the case? I have a similar step where I need to install pandoc through brew and that works as expected and is found when I run the R command that requires it later on (removed from code for simplicity but that one does work as expected when running my R code and is found). You can find the run from the screenshots above here: https://github.com/ries9112/XQuartz-Test/runs/1306009115?check_suite_focus=true

Here is a simplified .yml file that runs the workflow and reproduces my issue:

name: Run Tutorial
on: [push]
jobs:

build:

runs-on: macOS-10.15

steps:

- uses: actions/checkout@v2

- uses: r-lib/actions/setup-r@v1

- name: Install XQuartz for rayshader

run: |

brew cask install xquartz

- name: Install Packages

run: |-

Rscript -e "install.packages('devtools')"

Rscript -e "devtools::install_github('tylermorganwall/rayshader')"

Any thoughts on getting this to work? Any help would be much appreciated!
