通过 R-CMD-check

如何解决通过 R-CMD-check

我的包的依赖项之一是 rgl 包。当我尝试使用配置通过 Github Actions 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 包的问题（windows 没有问题）。确切的错误消息是：

Error in dyn.load(dynlib <- getDynlib(dir)) : 
  unable to load shared object '/Users/runner/work/_temp/Library/rgl/libs/rgl.so':

这已与 Installing "rgl" package in R,Mac OSX El Captian 和 Package rgl in R not loading in Mac OS 中的不同解决方案一起报告。但是，我不知道如何为 Githubs Actions R-CMD-check 调整这些解决方案。有没有人知道如何做到这一点？

解决方法

解决方案是在 RGL_USE_NULL: true 部分设置 env:，感谢@user2554330 (Package rgl in R not loading in Mac OS)
