通过 R-CMD-check 在 R Mac OS 中安装 rgl package

Question

我的 package 的依赖项之一是 rgl package。 当我尝试通过 Github Actions 使用配置进行 R-CMD 检查时

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

通过设置

usethis::use_github_action_check_standard()

我遇到了 rgl package 的问题（Windows 没有问题）。 确切的错误信息是：

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，我看不出如何将这些解决方案用于 Githubs Actions R-CMD-check。 有谁知道如何做到这一点？

解决方案是在env:部分设置RGL_USE_NULL: true ，.. 感谢@user2554330（ R 中的 Package rgl 未在 Mac OS 中加载）
