通過 R-CMD-check 在 R Mac OS 中安裝 rgl package

Question

我的 package 的依賴項之一是 rgl package。 當我嘗試通過 Github Actions 使用配置進行 R-CMD 檢查時

- {os: macOS-latest, r: 'release'}

通過設置

usethis::use_github_action_check_standard()

我遇到了 rgl package 的問題（Windows 沒有問題）。 確切的錯誤信息是：

Error in dyn.load(dynlib <- getDynlib(dir)) : 
  unable to load shared object '/Users/runner/work/_temp/Library/rgl/libs/rgl.so':
  dlopen(/Users/runner/work/_temp/Library/rgl/libs/rgl.so, 6): Library not loaded: /opt/X11/lib/libGLU.1.dylib
  Referenced from: /Users/runner/work/_temp/Library/rgl/libs/rgl.so
  Reason: image not found

    This build of rgl depends on XQuartz, which failed to load.

This has already be reported together with different solutions in Installing "rgl" package in R, Mac OSX El Captian and Package rgl in R not loading in Mac OS . 但是，我看不出如何將這些解決方案用於 Githubs Actions R-CMD-check。 有誰知道如何做到這一點？

解決方案是在env:部分設置RGL_USE_NULL: true ，.. 感謝@user2554330（ R 中的 Package rgl 未在 Mac OS 中加載）
